American Redstart
Setophaga ruticilla
Description
The sexual
dimorphism in this species is very strong. Its black, orange and white
plumage distinguish the adult male, and in flight an orange patch that
can be seen at the base of the male's primary and secondary feathers.
The female plumage is yellow on grey. During their first breeding season,
males have plumage similar to females.
Habitat
The American Redstart is a summer resident that typically breeds within a variety of moist open portions of deciduous and mixed woodlands and secondary forests that are often located near water.
Song
The American
Redstart is conspicuously vocal with high-pitched song phrases that can
occur in a variety of song types and patterns, but is commonly represented
by "see see see see, tsit tsit tsit tsit, tsee tsee tsee tsee, tsee-bit
tsee-bit tsee-bit tsee-bit, tsita tsita tsita tsita, wee-see wee-see wee-see
wee-see."

Comments
The American
Redstart forages from the ground of the forest floor to the top of the
canopy sallying for flying insects, moreso than any other wood warbler,
and opportunistically eats small berries and fruit in the summertime.
The temperament of this species has been described as tame and inquisitive
and the bird will readily respond to pishing and squeaking.
The agonistic behaviour of this species includes diverse vocal displays,
aerial "circling" displays and non-aerial displays, which typically involve
interactions with Least Flycatchers as they share similar niches.
