Encyclopedia
The Snow Bunting sometimes colloquially called a snowflake, is a passerine
Passerine
A passerine is a bird of the order Passeriformes, which includes more than half of all bird species. Sometimes known as perching birds or, less accurately, as songbirds, the passerines form one of the most diverse terrestrial vertebrate orders: with over 5,000 identified species, it has roughly...

 border, and also Cape Breton Highlands.

Characteristics

It is fairly large and long-winged for a bunting, 15–18 cm long and with a wingspan of 32–38 cm, and weighing 26–50 g. In flight, it is easily identified by its large white wing patches. The breeding male is unmistakable, with all white plumage and a black back; the breeding female is grey-black where the male is solid black. In winter plumage, both sexes are mottled pale ginger, blackish and white above, and pale ginger and white below, with the males having more white than the females. The bill is yellow with a black tip, all black in summer males. Unlike most passerines, it has feathered tarsi, an adaptation to its harsh environment. No other passerine can winter as far north as this species apart from the Common Raven

.

The call is a distinctive rippling whistle, "per,r,r,rit" and the typical Plectrophenax warble "hudidi feet feet feew hudidi".

It builds its bulky nest in rock crevices. The eggs are blue-green, spotted brown, and hatch in 12–13 days, and the young are already ready to fly after a further 12–14 days.

, which differs in having even more white in the plumage. Hybrids between the two occur in Alaska, and they have been considered conspecific by some authors, though they are generally treated as separate species.

The species is not endangered at present, with good populations. It shows little fear of humans, and often nests around buildings in Arctic areas, readily feeding on grain or other scraps put out for it.
