Information about the Bird Field Sparrow
The field sparrow is distributed across eastern Canada and the eastern United States, with northern populations migrating southwards to southern United States and Mexico in the fall. The typical habitat of this bird is bushy country with shrubs and grassland. The nest is a cup-shaped construction built on the ground and hidden beneath a bush or clump of grass. The birds forage on the ground or in low vegetation, feeding mainly on seeds and insects. The population is thought to be in slow decline, but it is a common species with a wide range, and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".The field sparrow (Spizella pusilla) is a small New World sparrow in the family Emberizidae. It is about 140mm (6in) long and weighs about 12.5g (0.4oz). The head is grey with a rust-coloured crown, white eye-ring and pink bill. The upper parts are brown streaked with black and buff, the breast is buff, the belly is white and the tail is forked. There are two different colour morphs, one being greyer and the other more rufous.
Adults have brown upperparts, a buffy breast, a white belly, two whitish wing bars and a dark-brown forked tail. They have a grey face, a rusty crown, a white eye ring and a pink bill. They have rusty markings behind the eye. There are grey and rufous colour variants.
Their breeding habitat is brushy, shrubby fields across eastern North America. The nest is an open cup on the ground under a clump of grass or in a small thicket.
These birds are permanent residents in the southern parts of their range. Northern birds migrate to the southern United States and Mexico.
These birds forage on the ground or in low vegetation, mainly eating insects and seeds. They may feed in small flocks outside the nesting season.
The male sings from a higher perch, such as a shrub or fencepost, which indicates his ownership of the nesting territory. The song is a series of sad whistles ending in a trill, often compared to the accelerating sound of a bouncing ball.
This bird's numbers expanded as settlers cleared forests in eastern North America, but may have declined in more recent times. Despite this, it is a common species with a wide range, and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
