In the United States, black-billed magpies are protected under the Migratory Bird Treaty Act, but "[a] Federal permit shall not be required to control ... [magpies] when found committing or about to commit depredations upon ornamental or shade trees, agricultural crops, livestock, or wildlife, or when concentrated in such numbers and manner as to constitute a health hazard or other nuisance". They sometimes land on large mammals, such as moose or cattle, to pick at the ticks that often plague these animals. Since magpies don’t migrate, that’s a … The male will work on the outside wall gathering sticks whereas the female … Then without any real courtship behavior at all the male Bald Eagle mounted the female and they mated as I photographed them and as the magpie stood nearby. In Canada, black-billed magpies do not appear on the list of birds protected by the Migratory Birds Convention Act. Behavior [26] Provincial laws also apply, but in Alberta, magpies may be hunted and trapped without a license. It may, however, then move the food to another location, particularly if other magpies are in the vicinity, watching. Its appearance is distinguishable from other magpies by its dense plumage, shorter and rounder wings, longer tail, and its iridescent blue feathers. Range and Habitat. (Drawing by Elva Hamerstrom Paulson.) Males are on average six to nine percent larger and sixteen to twenty-four percent heavier than females, at 167–216 grams (5.9–7.6 oz), a wingspan of 205–219 millimeters (8.1–8.6 in), and tail lengths of 230–320 millimeters (9.1–12.6 in). They eat wild fruit and grain, as well as grasshoppers and beetles that they find while foraging on the ground (they sometimes find beetles by flipping cow dung). They sit on fenceposts and road signs or flap across rangelands, their white wing patches flashing and their very long tails trailing behind them. Fossil evidence indicates that the ancestral North American magpie had arrived in its current range around the mid-Pliocene (3–4 mya) and that the yellow-billed magpie lineage split off rather soon thereafter due to the Sierra Nevada uplift and the beginning ice ages. Where persecuted it becomes very wary, but otherwise it is fairly tolerant of human presence. In Idaho the death toll eventually amounted to an estimated 150,000. During courtship they also use a tail-spreading display. Not only should you envy the magpie’s house-building ability, but also its relationship skills. Historically associated with bison herds, it now lands on the back of cattle to clean ticks and insects from them. They often follow large predators, such as wolves, to scavenge or steal from their kills. Especially during the first half of the 20th century, black-billed magpies were considered detrimental to game-bird populations (they sometimes steal bird eggs) and domestic stock (they sometimes peck at sores on cattle), and were systematically trapped or shot. Once a partner is found, a male and female magpie will mate for life. The Black-billed Magpies range is pretty much restricted to the western portion of North America. Black-billed Magpies traditionally followed Native Americans and lived off the refuse of their bison hunts. The female initiates the pair bond by begging for food from the male, which begins courtship feeding. Black-billed Magpies live among the meadows, grasslands, and sagebrush plains of the West. Generally, telling the sex of an adult magpie is often quite easy. [16], The black-billed magpie often forms loose flocks outside of the breeding season. The female tends to the interior, forming a mud cup and lining it with grass. The species is not threatened and in some areas it has benefited from forest fragmentation and agricultural developments. Black-billed Magpie pairs share the work of building their domed nests, which vary widely in size but are typically about 30 inches high and 20 inches wide. 2017. The chicks hatch in 16-21 days and fledge when they are 25-29 days old. In Canada they arrive at the roosting site earlier in the evening and leave later in the morning on colder days. Only the female incubates, for 16–21 days. The black-billed magpie is a mid-sized bird that measures 45–60 centimeters (18–24 in) from tip to tail. In The Birds of North America (P. G. Rodewald, editor). Large predators such as wolves are commonly followed by black-billed magpies, who scavenge from their kills. (2019). Partners in Flight (2017). Cornell Lab of Ornithology, Ithaca, New York, USA. A bird of open country in California's central valleys. Find out more about what this bird likes to eat and what feeder is best by using the Project FeederWatch Common Feeder Birds bird list. Incubation, by the female only, starts when the clutch is complete, and lasts 16–21 days. [5], They also have a call given in the vicinity of their dead, causing a gathering often referred to as a funeral. North American Bird Conservation Initiative. Though they like open areas and are not found in dense woods, they stay close to cover for protection from raptors. All … In groups, males establish dominance through a stretch display: raising the bill in the air and flashing their white eyelids. Females weigh between 141–179 grams (5.0–6.3 oz), have wingspans of 175–210 millimeters (6.9–8.3 in), and tail lengths of 232–300 millimeters (9.1–11.8 in). (1999). The lifespan of the species in the wild is about four to six years. The breeding season for magpies is generally from late March to early July. The most noticeable physical difference between male and female magpies is the colouration of the white hoods located on their necks and the backs of their heads. ... the male does all of the heavy work. Longevity records of North American birds. When they find an abundant food source, magpies will cache food for short periods.Back to top. They sometimes gather in flocks, even seemingly living communally, and will band together to mob a raptor. During courtship they also use a tail-spreading display. The belly is pure white and they have white markings above the wings and below which can be seen when they are in flight. "Black-billed Magpie (, International Union for the Conservation of Nature, "A fossil magpie from the Pleistocene of Texas", "Distribution and abundance of the Black-billed magpie (, "Temperature regulation and climatic adaptation in Black-billed and Yellow-billed Magpies". Old nests are repaired and used, or a new nest is built on top, with older … Dissect a dead magpie to look for the bird's gonads--a pair of testes in males, an ovary in females. Raptors often build a nest on top of the magpie nest dome. Surprisingly, young males are often dominant over – or may just be tolerated by – adult males. To make a cache, the bird pushes or hammers its bill into the ground (or snow), forming a small hole into which it deposits the food items it was holding in a small pouch under its tongue. Black-billed Magpies are familiar and entertaining birds of western North America. This large, flashy relative of jays and crows is a social creature, gathering in numbers to feed at carrion. Explore Birds of the World to learn more. The Black-billed Magpie’s diet also includes grain, fruits, and small mammals. The male spreads and displays his tail to attract the female, and (in the case of the black-billed magpie) signals his interest with a flash of white wing patch. The female initiates the pair bond by begging for food from the male, which begins courtship feeding. They will nest in open woodlands, riparian thickets, farm fields, and suburban areas. They nest once a year, but may re-nest if their first attempt fails early. [22], Many suburban songbird lovers dislike magpies because of their reputation for stealing eggs, but studies have shown that eggs make up only a small proportion of what magpies feed on during the reproductive season. Male feeds female during egg-laying and incubation period. The female tends to the interior, forming a mud cup and lining it with grass. [11] At the roosting site they tend to occupy trees singly; they do not huddle. The head, back, wing coverts, tail and tarsus feathers are velvet-black with metallic gloss (especially on the tail) of purple, blue and green tones. [10] In Canada they arrive at the roosting site earlier in the evening and leave later in the morning on colder days. parental care than females. The male Black-billed Magpie brings the female food while she incubates the eggs. Externally, the black-billed magpie is almost identical to the European magpie, Pica pica, and is considered conspecific by many sources. [7], Black-billed magpies range in the north from coastal southern Alaska, central British Columbia, and the southern halves of Alberta, Saskatchewan, and Manitoba, through the Rocky Mountains down south to all the Rocky Mountain states including New Mexico, Colorado, Utah, Wyoming, Idaho, and some bordering states as well. The adult male and female are similar. Black-billed Magpies are familiar and entertaining birds of western North America. Houghton Mifflin Harcourt, New York, USA. •Nests are built by both sexes over a 40- to 50-day period. It is one of only four North American songbirds whose tail makes up half or more of the total body length (the others being the yellow-billed magpie, the scissor-tailed flycatcher, and the fork-tailed flycatcher). The Sibley Guide to Birds, second edition. Usually 6–7 eggs are laid. The female lays up to thirteen eggs, but the usual clutch size is six or seven. Cache robbing is fairly common so a magpie often makes several false caches before a real one. The av­er­age lifes­pan of male black-billed mag­pies is 3.5 years, fe­males live on av­er­age 2 years, al­though these num­bers may rep­re­sent rel­a­tively high lev­els of mor­tal­ity of the young, with av­er­age ages being higher when first year mor­tal­ity is not con­sid­ered. Get Instant ID help for 650+ North American birds. Nests are built by both sexes over 40–50 days, starting in February (though later in northern parts of the range). During breeding, the male stands guard near the female to reduce the chance she’ll mate with another male (which does occur). When the bison herds were devastated in the 1870s, magpies switched to cattle, and by the 1960s they had also moved into the emerging towns and cities of the North American West. I was setting up camp in Arches National Park and noticed large, crow-like birds strutting with their striking contrasts of black and white feathers. Some 20 species are known worldwide; however, only the black-billed magpie (Pica hudsonia) is found in Canada. [6]:185 When threatened, the black-billed magpie utters a shrill scream. Details: Visited yard twice to check for peanuts. This species prefers generally open habitats with clumps of trees. They rate a 7 out of 20 on the Continental Concern Score and they are not on the 2014 State of the Birds Watch List. The black-billed magpie is one of the few North American birds that build a domed nest. Fledging success (usually 3–4 young per nest) is lower than clutch size; this is not an unusual state of affairs in species with asynchronous hatching, as some nestlings often die of starvation. The engage in funeral-like behavior for dead magpies where up to 40 magpies gather for 10 to 15 minutes. "Roost characteristics and roosting behaviour of Black-billed Magpies, "Sleeping behavior of Black-billed Magpies under a wide range of temperatures". 6-7, sometimes 5-9, rarely more. At the roosting site they tend to occupy trees singly; they do not huddle. Incubation is by female, 16-21 days, usually about 18. Both adults construct these large nests, the male generally relegated to building the stick (outer) portion of the nest, while the female lines the interior with finer materials and mud. Nests are loose but large accumulations of branches, twigs, mud, grass, rootlets, bark strips, vines, needles, and other materials, with branches and twigs constituting the base and framework. Highly social birds, they live in large groups that can contain over fifty individuals. It can therefore be found in farmlands and suburban areas, where it comes into regular contact with people. The adult Black-billed Magpie is 45–60 cm (18–24 in) long and weighs 145-210 g (5-7.5 ounces). The female will beg the male for food (which, if he’s interested, he answers by feeding her). In Black-billed Magpies (Pica pica), the sexes have relatively similar levels of parental care. In the past Black-billed Magpies were persecuted by farmers, ranchers, and game managers who considered them to be vermin, but today they are fully protected under the Migratory Bird Treaty Act.Back to top. [12] During the night they may also regurgitate, in the form of pellets, the undigested parts of what they ate during the day. Female magpies tend to be greyer at the lower end of the hood, while adult male magpies will have very white hoods right to the bottom. Within this limited region, Yellow-billeds nest in colonies in groves of tall trees. The twelve adult (seven male, five female) Yellow-billed Magpies were cap- tured near Davis, Yolo Co., California, in summer, 1979. Black-billed Magpies mate for life. Helpless and naked with pink skin. Dominants can steal food from subordinates. Black-billed Magpie (Pica hudsonia), version 2.0. Sometimes they steal meat from the kills of coyotes and foxes. [3] A comparatively low genetic difference, however, suggests that some gene flow between the black-billed and yellow-billed magpies still occurred during interglacial periods until the Pleistocene. Like many corvids, however, it is susceptible to West Nile virus. When this happens (usually in areas with a limited number of trees or with abundant food resources), a diffuse colony is formed. Black-billed magpies are also known to make food caches in the ground, in scatter-hoarding fashion. They have been vulnerable to toxic chemicals, particularly topical pesticides applied to the backs of cattle which magpies ingest when gleaning ticks off livestock. [20], If regularly disturbed at the nest, magpie pairs will eventually either move the eggs[21] or abandon the clutch altogether, but in the first instance they will defend the nest aggressively. The male gathers sticks for the exterior. After this the bird cocks its head and stares at the cache, possibly to commit the site to memory. The Cornell Lab will send you updates about birds, birding, and opportunities to help bird conservation. The pairs seem to choose a nesting site together (though sometimes they disagree and each begin building separate nests in different locations). Both parents bring food to nestlings. The male feeds the female throughout incubation. Every evening they fly, often in groups and sometimes over long distances, to reach safe roosting sites such as dense trees or shrubs that impede predator movement, or, at higher latitudes, dense conifers that afford good wind protection. Sauer, J. R., J. E. Hines, J. E. Fallon, K. L. Pardieck, Jr. Ziolkowski, D. J. and W. A. Not only should you envy the magpie’s house-building ability, but also its relationship skills. The Cornell Lab of Ornithology describes its call as a ka-ka-ka-ka, often preceded with a skah-skah. Pete Dunne's essential field guide companion. The final cache is covered with grass, leaves, or twigs. They sleep with the bill t… The State of the Birds 2014 Report. Nesting Behavior. Once a partner is found, a male and female magpie will mate for life. Black-billed magpies breed for the first time at one or two years of age. On male magpies, the hood is a vibrant white throughout; the hood on female magpies is greyish toward the bottom. Never did see more than one at a time. According to the Animal Diversity Web, female black-billed magpies devote most of their energy at this stage to hollowing out a depression for their eggs, while males mostly build the protective nest-dome, often made of twigs and mud. The male protects the nest and helps feed the chicks. On the wing, Black-billed Magpies make long, sweeping flights with white flashes of their wing patches and long, trailing tails. The range extends as far east as northern Minnesota and Iowa, with casual records in northern Wisconsin and upper Michigan, but is thought to be limited further east and south by high temperature and humidity. So if you are driving across the country you don t need to start looking for one until you reach Wichita, Kansas. The eggs are greenish grey, marked with browns, and 33 mm (about 1.3 inch) long. USGS Patuxtent Wildlife Research Center (2014b). The male and female will work together in nest building. [25] State or local regulations may limit or prohibit killing these birds as well. A. and A. S. Love. Black-billed magpie pairs may mate for life. Highly social birds, they live in large groups that can contain over fifty individuals. Male: Female: Sex Unknown: 1: Black-billed Magpie. The bird relocates its caches by sight and also by smell; during cache robbing, smell is probably the primary cue. The black-billed magpie is an opportunistic omnivore, eating many types of insects, carrion, seeds, rodents, berries, nuts, eggs, and also garbage and food from pets that are fed outside. Young: Both parents bring food to nestlings. 1 brood per year. They are fairly common in small towns and may visit large yards. The male is larger than the female (16-20% heavier). (2014). Aggressive interactions also occur at point sources of food. Mating Bald Eagles on ice with a Black-billed Magpie nearby – Nikon D500, f7.1, 1/2500, ISO 500, +0.7 EV, Nikkor 500mm VR with 1.4x TC, natural light, not baited (2014). A black-billed magpie's beak is oblong, and weakly curved toward the tip. One of the most notable Black-billed Magpie behaviors is the so-called “funeral”—when one magpie discovers a dead magpie, it begins calling loudly to attract other magpies. Number observed: 1. The gathering of loudly calling magpies (up to 40 birds have been observed) may last for … [24], Because of its enormous range and stable population, the black-billed magpie is rated as a species of least concern by the International Union for the Conservation of Nature.[1]. Male and females look similar although the male is slightly larger. [4]:120 The tail of a black-billed magpie is made up of long, layered feathers, the middle pair of which protrude farthest of all. We removed male magpies during the laying period to early in the nestling period and found that 100% of unaided females failed to produce any offspring (n Like American crows, magpies tend to roostcommunally in winter. [23] In England, the European magpie also has a reputation for taking eggs, and yet when density of magpie populations increases, songbird density does not decrease; on the contrary, it increases too. Every evening they fly, often in groups and sometimes over long distances, to reach safe roosting sites such as dense trees or shrubs that impede predator movement, or, at higher latitudes, dense conifers that afford good wind protection. Eyes are closed for the first 7 days. Only the nest tree and its immediate surroundings are defended, and so it is possible for nests to be somewhat clumped in space. The nest cup is lined with fine rootlets, grass, and other soft material. Tan or olive-brown with variable amount of dark brown speckles. Such hoards are short-term; the food is usually recovered within several days, or the bird never returns. Black-Billed Magpie With their large size, bold pied plumage, and fondness for open areas, black-billed magpies are easily seen. Like crows and jays, both close relatives, magpies pick up shiny objects and place them in the nest. ^ Buitron, D., 1988, Female and male specialization in parental care and its consequences in Black-billed magpies, Condor 90: 29-39 ^ Dhindsa, M.S., and D.A. "Regurgitated pellets and late winter diet of Black-billed Magpies, "Female and male specialization in parental care and its consequences in Black-billed magpies", "Experiments on olfactory detection of food caches by black-billed magpies", Title 50 Code of Federal Regulations Section 21.43, Birds protected under the Migratory Birds Convention Act, Alberta Wildlife Act, Schedule 4, Part 6 Non‑licence Animals, Washington Department of Fish and Wildlife, Living with Wildlife; Facts about Magpies, https://en.wikipedia.org/w/index.php?title=Black-billed_magpie&oldid=987195260, Native birds of the Plains-Midwest (United States), Native birds of the Northwestern United States, Native birds of the Western United States, Short description is different from Wikidata, Creative Commons Attribution-ShareAlike License, This page was last edited on 5 November 2020, at 14:48. Black-billed Magpies now frequent farms and ranches, and have been known to rob trap-lines, take poultry eggs, and raid orchards. Black-billed magpies mate for life. The tail is long with a glossy purple band near the tip. Hatching is often asynchronous. Magpie is a common name for birds of several genera in the crow family. Nests almost always include a hood or dome of loosely assembled twigs and branches, and usually have one or more side entrances. The first time I encountered the mischievous antics of a black-billed magpie was during my first cross-country drive. It is black and white, with black areas on the wings and tail showing iridescent hints of blue or blue-green. Black-billed Magpie pairs share the work of building their domed nests, which vary widely in size but are typically about 30 inches high and 20 inches wide. The species also walks on the ground, where it obtains such food items as beetles, grasshoppers, worms, and small rodents. Biologists who have climbed nest trees to measure magpie eggs have reported that the parents recognized them personally on subsequent days and started to mob them, overlooking other people in the vicinity. US Department of Interior, Washington, DC, USA. They fly 3–4 weeks after hatching, feed with adults for about two months, and then fly off to join other juvenile magpies. The black-billed magpie, the ones outside my window, have been seen to hold a “funeral.” When one magpie discovers a dead one, it begins calling loudly to attract other magpies. This nest is made up of twigs and sits near the top of trees. Black-billed Magpie Regional Species. It takes about six weeks for the female and male to construct this complex and sturdy nesting structure, and the pair may use it for several years. Number observed: 1. Their nesting territories often follow stream courses. Magpies typically forage on the ground, usually walking, sometimes hopping, and sometimes scratching with their feet to turn over ground litter. Carrion is also a main food source, as are the fly maggots found in carrion. The distinguishing feature lies in the white hood on the back of their heads and necks. The nine adult (six male, three female) Black- billed Magpies used in this study were col- lected near Pocatello, Bannock Co., Idaho, in summer, 1978. Boag, 1992, Patterns of nest site, territory and mate switching in Black-billed Magpies, Canadian Journal of Zoology 70: 633-640. [27], Trost, C.H. Other bird species, including small hawks and owls, often use old magpie nests. While courting the female black-billed magpies stand next to the female to ensure she doesn’t mate with any other male in the flock. They were considered vermin, and many Black-billed Magpies were killed as pests in the early 20th Century. [8][9], Like American crows, magpies tend to roost communally in winter. The Black-billed Magpie is well known bird having contrast black and white coloring and the long strongly graduated tail which is fan-shaped in flight. The male brings her food while she is incubating the eggs. The black-billed magpie retreated from many parts of its former range in North America when the large herds of bison disappeared. Link. Alfred A. Knopf, New York, NY, USA. Both sexes seem to choose a nesting site together (though sometimes they disagree and each begin building separate nests in different locations). In this the black-billed magpie is intermediate between the European magpie, whose nests are much more spread out because a large territory is defended around each nest, and the yellow-billed magpie, which is always loosely colonial. The black-billed magpie (Pica hudsonia), also known as the American magpie, is a bird in the corvidae family that inhabits the western half of North America, from Colorado, to southern coastal Alaska, to Central Oregon, to northern California, northern Nevada, northern Arizona, northern New Mexico, central Kansas, and Nebraska. The tail is long and makes up half of the bird's length. Divorces are possible: one South Dakota study found low rates of divorce (8%)[14] but one 7-year study in Alberta found divorce rates up to 63%.[15]. The North American Breeding Bird Survey, results and analysis 1966-2013 (Version 1.30.15). The adult male has a mostly white back with a narrow black stripe, and the female a blackish back; the black feathers here are tipped with white similar to subspecies dorsalis. Since magpies don’t migrate, that’s a great deal of time to spend together. Version 1019 Patuxent Wildlife Research Center, Bird Banding Laboratory 2019. Available from http://www.mbr-pwrc.usgs.gov/bbs/. They build their dome nests in conifer trees, deciduous trees, shrubs, utility poles, and even in deserted buildings. They sit on fenceposts and road signs or flap across rangelands, their white wing patches flashing and their very long tails trailing behind them. In their range, Black-billed Magpies occasionally visit platform bird feeders and suet feeders. Magpies walk with a swaggering strut. Wingspan is about 60 cm (24 in). Old nests can be repaired and used, or a new nest can be built on top, with older nests thus reaching 120 cm high by 100 cm wide (48 inches high by 40 inches wide). [5], The vocalizations of the black-billed magpie consist of a series of rough, scratchy calls. Black-billed magpies will also raid from the nests of other birds and kill squirrels and voles and other small mammals. K326207 Black-billed Magpie.jpg: K326224 Black-billed Magpies.jpg: K326237 Black-billed Magpie.jpg: K326239 Black-billed Magpie.jpg: K326264 Black-billed Magpie.jpg They hop and walk on the ground with a swaggering and confident gait. [17][18], When Lewis and Clark first encountered magpies in 1804 in South Dakota, they reported the birds as being very bold, entering tents or taking food from the hand. [19] Magpies formerly followed American bison herds (from which they gleaned ticks and insects), as well as the bands of Plains Indians that hunted the bison so they could scavenge carcasses. They also show aggression with their wings, flickering or quivering them to display the white wing patches; and tails spreading, quivering, or flicking their elongated tail feathers. Trost, Charles H. (1999). While its Black-billed relative lives across Europe, Asia, and North Africa, as well as western North America, the Yellow-billed Magpie lives only in California -- in an area about 500 miles from north to south and less than 150 miles wide. Young. Avian Conservation Assessment Database. During the winter months, magpies often roost together in large groups of 100 or more birds. Lutmerding, J. Partners in Flight estimates the global breeding population at 5.4 million, with 63% spending part of the year in the U.S., and 50% in Canada. Pairs sometimes mate for life. The nestling period is 3–4 weeks. Greenish gray, heavily spotted with brown. Hatched young are altricial, brooded by the female but fed by both sexes. They perch at the tops of trees, which is a means of visually establishing their territory, the equivalent of other bird species’ songs. Black-billed magpies nest individually, frequently toward the top of trees. Dunne, P. (2006). The American Ornithologists' Union, however, splits it as a separate species, Pica hudsonia, on the grounds that its mtDNA sequence is closer to that of California's yellow-billed magpie, Pica nuttalli, than to the European magpie.

Such pellets can be found on the ground and then used to determine at least part of the birds' diet. Today black-billed magpies remain relatively tame in areas where they are not persecuted. The black-billed magpie is a black-and-white, pigeon-sized bird with an unusually long tail. The gathering of raucously calling magpies (up to 40 birds have been observed) may last for 10 to 15 minutes before the birds disperse and fly off silently. The New Guinean magpie, G. tibicen papuana, is a little-known subspecies found in southern New Guinea. Bounties of one cent per egg or two cents per head were offered in many states. Unlike other members of the Corvidae family, the black-billed magpie is strongly dimorphic. Magpies have a black bill, dark brown eyes and black legs and feet. It has a long deep bill resembling that of subspecies longirostris. Crows, Jays, and Magpies(Order: Passeriformes, Family:Corvidae). Sibley, D. A. Magpies also land atop large animals, such as cows or moose, and pick ticks off them. In 1933, 1,033 magpies were shot in Washington's Okanogan valley by two teams of bounty hunters. [5] This call is thus very different from that of the Eurasian magpie, and is similar to those of the yellow-billed magpie. Magpies don’t avoid human development, often spending time near barnyards, livestock areas, and grain elevators where they have ready access to food.Back to top, Like other corvids (members of the jay and crow family), Black-billed Magpies have a wide-ranging diet. Many magpies also died from eating poison set out for coyotes and other predators. If this view is correct, the Korean subspecies of the European magpie, Pica pica sericea, should also be considered a separate species.[2]. [13], Adult black-billed magpie pairs stay together year-round and often for life unless one dies, in which case the remaining magpie may find another mate. They also kill small mammals such as squirrels and voles, and raid birds’ nests. The female lays four to nine eggs and incubates them. However, they become very wary in areas where they are often shot at or disturbed. They sleep with the bill tucked under the scapular (shoulder) and back feathers, adopting this position sooner on colder nights. Young leave nest about 25-29 days after hatching. The male gathers sticks for the exterior. It appears that after the ancestral magpie spread over Eurasia, the Korean population became isolated, at which point the species crossed the Bering Land Bridge and colonized North America, where the two American magpies then differentiated. Chicks are fed animal matter almost exclusively. Dominance hierarchies may develop within such flocks. Back to top, Black-billed Magpies populations have been decreasing every year from 1966 to 2014, particularly on prairies, resulting in a cumulative decline by about 26%, according to the North American Breeding Bird Survey.
