Chestnut-sided Warbler

Species: The Chestnut-sided Warbler (Dendroica castanea) finds it habitat in over grown fields, second growth forest and bushy meadows. Shows the same characters as the wrens, gives the appearance of drooping wings when seen perched. Easy to approach when singing, usually in bushes or smaller trees in an open area. Has greatly increased in numbers in the 1900s because of all available open space from abandon farmsteads. It was consider a rare bird, when first seen in the 1800s, because the continent was covered in mature trees.

Distinctions: The male in breeding plumage has a yellow crown and has a black supercilium, its back is streaked black and white, black wings, with two white wing bars, white cheeks, with a black moustache, chestnut coloured flanks, white breast and undertail coverts. In non-breeding the male is mostly gray and lime green, still showing the chestnut flanks. The female is very similar with all of the male's characteristics, but to a lesser degree. The juvenile has greenish cheeks, crown, nape and back, dark wings with two white wing bars, greenish-white breast and supercilium.

Voice: Chipping call, buzzy notes, songs sound like "very pleased to MEET-CHA", repeated often.

Nesting: Three to five white to off-white coloured eggs with brown markings. Builds nest low in shrubs of trees. The nest is composed of leaves, twigs, mosses, and lined with fine grasses and hair.
