American common magpie

The **American common magpie** (*Pica americanus*) is a species of magpie, most closely related to the similarly-looking Eurasian magpie (*Pica pica*), that originally did not exist, but has since been created by SciiFii and introduced throughout the rainforests, wetlands, forests, and open woodlands across North America to help boost biodiversity. The adult male American common magpie is between 44–46 centimeters (17–18 inches) in length, of which more than half is the tail. The wingspan is 52–62 centimeters (20–24 inches). The head, neck and breast are glossy black with a metallic green and violet sheen; the belly and scapulars (shoulder feathers) are pure white; the wings are black glossed with green or purple, and the primaries have white inner webs, conspicuous when the wing is open. The graduated tail is black, glossed with green and reddish purple. The legs and bill are black; the iris is dark brown. The plumage of both sexes is similar but females are slightly smaller. American common magpies have a well-known call. It is a choking chatter "chac-chac" or a repetitive "chac-chac-chac-chac". The young also emit the previous call, although they also emit an acute call similar to a "Uik Uik", which may resemble the barking of a small dog. Both adults and young can emit a kind of hiss barely noticeable from afar. The American common magpie is very intelligent, about as smart as the Eurasian magpie, being able to engage elaborate social rituals, including the expression of grief. Mirror self-recognition has been demonstrated in American common magpies. Another behaviour exhibiting intelligence is cutting their food in correctly sized proportions for the size of their young. In captivity, American common magpies have been observed counting up to get food, imitating human voices, and regularly using tools to clean their own cages. In the wild, they organise themselves into gangs and use complex strategies hunting other birds and when confronted by predators. The American common magpie is omnivorous, eating young birds and eggs, small mammals, insects, scraps and carrion, acorns, grain, and other vegetable substances. Some American common magpies breed after their first year, while others remain in the non-breeding flocks and first breed in their second year. They are monogamous, and the pairs often remain together from one breeding season to the next. They generally occupy the same territory on successive years. Mating takes place in spring. In the courtship display, males rapidly raise and depress their head feathers, uplift, open and close their tails like fans, and call in soft tones quite distinct from their usual chatter. The loose feathers of the flanks are brought over the primaries, and the shoulder patch is spread so the white is conspicuous, presumably to attract females. Short buoyant flights and chases follow. American common magpies prefer tall trees or buildings for their bulky nest, firmly attaching them to a central fork in the upper branches. A framework of the sticks is cemented with earth and clay, and a lining of the same is covered with fine roots. Above is a stout though loosely built dome of prickly branches with a single well-concealed entrance. These huge nests are conspicuous when the leaves fall. Where trees are scarce, though even in well-wooded country, nests are at times built in bushes and hedgerows. Clutches are typically laid in April, and usually contain five or six eggs, but clutches with as few as four and as many as eleven have been recorded. The eggs are laid in early morning, usually at daily intervals. On average, the eggs measure 32.9 mm × 23 mm (1.30 inches × 0.91 inches) and weigh 9.9 g (0.35 oz). Small for the size of the bird, they are typically pale blue-green, with close specks and spots of olive brown, but show much variation in ground and marking. The eggs are incubated for 21–22 days by the female, who is fed on the nest by the male. The chicks are altricial, hatching nearly naked with closed eyes. They are brooded by the female for the first 5–10 days and fed by both parents. Initially the parents eat the faecal sacs of the nestlings, but as the chicks grow larger, they defecate on the edge of the nest. The nestlings open their eyes 7 to 8 days after hatching. Their body feathers start to appear after around 8 days and the primary wing feathers after 10 days. For several days before they are ready to leave the nest, the chicks clamber around the nearby branches. They fledge at around 27 days. The parents then continue to feed the chicks for several more weeks. They also protect the chicks from predators, as their ability to fly is poor, making them vulnerable. On average, only 3 or 4 chicks survive to fledge successfully. Some nests are lost to predators, but an important factor causing nestling mortality is starvation. American common magpie eggs hatch asynchronously, and if the parents have difficulty finding sufficient food, the last chicks to hatch are unlikely to survive. Only a single brood or two is reared, unless disaster overtakes either or both clutches. The conservation status of the American common magpie is **Least Concern** due to successful conservation efforts, the American common magpie's wide range and its tolerance to many of the human activities.
