Birds of Canada

male                female

The lark bunting (Calamospiza melanocorys) is a medium-sized American sparrow native to central and western North America.

Lark buntings are small songbirds, with a short, thick, bluishbill. There is a large patch of white on the wings and they have a relatively short tail with white tips at the end of the feathers. Breeding males have an all black body with a large white patch on the upper part of the wing. Nonbreeding males and females look similar and are grayish brown with white stripes.



The Franklin's gull (Leucophaeus pipixcan) is a small gull.
It breeds in central provinces of Canada and adjacent states of the northern United States. It is a migratory bird, wintering in Argentina, the CaribbeanChile and Peru.
The summer adult's body is white and its back and wings are much darker grey than all other gulls of similar size except the larger laughing gull. The wings have black tips with an adjacent white band. The bill and legs are red. The black hood of the breeding adult is mostly lost in winter.
Young birds are similar to the adult but have less developed hoods and lack the white wing band. They take three years to reach maturity.
Although the bird is uncommon on the coasts of North America, it occurs as a rare vagrant to northwest Europe, south and west AfricaAustraliaand Japan, with a single record from EilatIsrael, in 2002 (Smith 2002).



The dickcissel (Spiza americana) is a small Americanseed-eating bird in the family Cardinalidae. It is the only member of the genus Spiza, though some sources list another supposedly extinct species (see below). In older works, it is often placed with the American sparrows in theEmberizidae; females especially resemble American sparrows in plumage.
Dickcissels have a large pale bill, a yellow line over the eye, brownish upperparts with black streaks on the back, dark wings, a rust patch on the shoulder and light underparts. Adult males have a black throat patch, a yellow breast and grey cheeks and crown. This head and breast pattern is especially brilliant in the breeding plumage, making it resemble an eastern meadowlark. Females and juveniles are brownish on the cheeks and crown and are somewhat similar in appearance to house sparrows; they have streaked flanks.
In flight they make a low, "electric", buzzing fpppt. From an open perch in a field, this bird's song is a sharp dick dickfollowed by a buzzed cissel, also transcribed as skee-dlees chis chis chis or dick dick ciss ciss ciss.


The marbled godwit (Limosa fedoa) is a large shorebird. On average, it is the largest of the 4 species of godwit. The total length is 40–50 cm (16–20 in), including a large bill of 8–13 cm (3.1–5.1 in), and wingspan is 70–88 cm (28–35 in).[2] Body mass can vary from 240 to 510 g (8.5 to 18.0 oz).[3]
Adults have long blue-grey hairy legs and a very long pink bill with a slight upward curve and dark at the tip. The long neck, breast and belly are pale brown with dark bars on the breast and flanks. The back is mottled and dark. They show cinnamon wing linings in flight.
Their breeding habitat is the northern prairies of westernCanada-(Canadian Prairies), and the north central Great PlainsUnited States near marshes or ponds. They nest on the ground, usually in short grass.
In autumn, they migrate in flocks to the coasts of California, the Gulf of MexicoMexico and South America.
These birds forage by probing on mudflats, in marshes, or at the beach (see picture below). In short grass, they may pick up insects by sight. They mainly eat insects andcrustaceans, but also eat parts of aquatic plants.
Their numbers were reduced by hunting at the end of the 19th century. Although they had recovered somewhat since that time, their population has declined in recent times as suitable habitat is used for farming.

The sharp-tailed grouse (Tympanuchus phasianellus) (previously: Tetrao phasianellus), is a medium-sized prairie grouse. It is also known as the sharptail, and is known as "fire grouse" or "fire bird" by Native American Indians due to their reliance on brush fires to keep their habitat open. 

The chestnut-collared longspur (Calcarius ornatus) is a small ground-feeding bird from the family Calcariidae which also contains the longspurs.
These birds have a short conical bill, a streaked back and a white tail with a dark tip. In breeding plumage, the male has black underparts, a chestnut nape, a yellow throat and a black crown. Other birds have light brown underparts, a dark crown, brown wings and may have some chestnut on the nape.
This bird breeds in short and mixed grass prairies in centralCanada and the north central United States. The female lays 4 or 5 eggs in a grass cup nest in a shallow scrape on the ground. The male sings and flies up to defend his territory. Both parents feed the young birds.
In winter, they migrate in flocks to prairies and open fields in the southern United States and Mexico.
These birds forage on the ground, gathering in flocks in winter. They mainly eat seeds, also eating insects in summer. Young birds are mainly fed insects.
The call is a two-syllabled chee dee.

The black-billed magpie (Pica hudsonia), also known as the American magpie, is a bird in the crow family that inhabits the western half of North America, from southern coastal Alaska down the Rocky mountains to northern California, northern Arizona, northern New Mexico, central Kansas, and Nebraska. It is black and white, with black areas on the wings and tail showing iridescent hints of blue or blue-green. 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).
This species prefers generally open habitats with clumps of trees. It can therefore be found in farmlands and suburban areas, where it comes into regular contact with people. Where persecuted it becomes very wary, but otherwise it is fairly tolerant of human presence. Historically associated with bison herds, it now lands on the back of cattle to glean ticks and insects from them. Large predators such as wolves are commonly followed by black-billed magpies, who scavenge from their kills. The species also walks on the ground, where it obtains such food items as beetles, grasshoppers, worms, and small rodents.
The black-billed magpie is one of the few North American birds that build a domed nest. This nest is made up of twigs and sits near the top of trees. Usually 6-7 eggs are laid. Incubation, by the female only, starts when the clutch is complete, and lasts 16-21 days. The nestling period is 3-4 weeks.

The purple martin (Progne subis) is the largest North American swallow. These aerial acrobats have speed and agility in flight, and when approaching their housing, will dive from the sky at great speeds with their wings tucked.
Purple martins are a kind of swallow, of the genus Progne. Like other members of this genus, they are larger than most of the other swallows. The average length from bill to tail is 20 cm (7.9 in). Adults have a slightly forked tail. Adult males are entirely black with glossy steel blue sheen, the only swallow in North America with such coloration.
Adult females are dark on top with some steel blue sheen, and lighter underparts. Subadult females look similar to adult females minus the steel blue sheen and browner on the back. Subadult males look very much like females, but solid black feathers emerge on their chest in a blotchy, random pattern as they molt to their adult plumage.
This species was first described by Linnaeus in hisSystema naturae in 1758 as Hirundo subis. The species of this genus are very closely related, and some view the purple martin, gray-breasted martin, snowy-bellied martin, and southern martin, as a superspecies.



The western meadowlark (Sturnella neglecta) is a medium-sized icterid bird, about 8.5 in (22 cm) long. It nests on the ground in open country in western and central North America grassland. It feeds mostly on insects, but also seeds and berries. It has distinctive calls described as watery or flute-like, which distinguish it from the closely related eastern meadowlark.
