American Redstart

One of the more acrobatic, energetic and brilliantly coloured warblers is the American Redstart. This Spring is the first that I've ever heard of this warbler, thanks for my mom pointing it out to me. The American Redstart has a unique method of catching its prey. It will fan out its wings and tail while foraging on the ground, scaring insects into moving by flashing its bold colours. To further aid the Redstart in detecting insects, it uses hair-like feathers called rictal bristles at the corners of its mouth. American Redstarts live up to 10 years and can grow 13 cm long with a wingspan of 20 cm.
Voice:
Its call is a harsh tsiip and when in flight it makes a high-pitched sveep. The Redstart's song is high, thin and confusingly variable with its series of notes, such as see-a see-a see-a see-a ZEE-urrr.
