Bruant de Henslow— faune du Québec

Henslow's sparrow (Centronyx henslowii) is a North American passerine bird in the family Passerellidae. It was named by John James Audubon in honor of John Stevens Henslow. It was originally classified in the genus Emberiza and called Henslow's bunting.

Description

Adults have streaked brown upperparts with a light brown breast with streaks, a white belly and a white throat. They have a pale stripe on the crown with a dark stripe on each side, an olive face and neck, rust-coloured wings and a short dark forked tail. Measurements: Length: 4.3–5.1 in (11–13 cm) Weight: 0.4–0.5 oz (11–14 g) Wingspan: 6.3–7.9 in (16–20 cm)

Reproduction

Their breeding habitat is shrubby fields, often wet, in southern Canada, the northeastern United States, and the midwestern United States. In 2020, the Central Kentucky Audubon Society discovered that a population of Henslow's sparrows near a winery only needed 5 acres of grassy habitat to successfully breed (previous research had suggested at least 20 to 75 acres were necessary). The nest is a well-concealed open cup on or close to the ground in a grassy location; these birds often nest in small colonies. They migrate to marshes and open pine woods in the southeastern United States.
