White-throated Sparrows

The White-throated Sparrows (Zonotrichia albicollis) are migratory American sparrows that occur naturally in Canada and southern USA.

These sparrows follow a well-defined hierarchy, which puts males ahead of females and older sparrows ahead of younger birds.

They are rare vagrants to Western Europe.

Description

White-throated Sparrows

White-throated Sparrows measure 17 cm in length, including its long tail.

They are easily identified by their reddish-brown wings and white throats.

There are two types – one has white stripes on its crown (the more common form) and the other has tan stripes and a browner head.

Those with white stripes tend to be more vocal and aggressive than those with tan stripes.

Adult sparrows go through two molts a year – in late summer and late winter. Juveniles undergo three molts in their first year – referred to as first plumage-cycle.

Diet / Feeding

White-throated Sparrows forage on the ground under or near thickets or in low vegetation. They mainly eat seeds, insects and berries.

They will also readily visit bird feeders, and are – in fact – the most widespread sparrows at feeders.
