NAME: ‘Thrush’ would mean ‘to twitter’. ‘Varied’ refers to the male plumage. Latin genus name ‘Ixoreus’ means ‘mountain mistletoe’. This is because a European thrush has been associated with this plant from the time of Aristotle (Choate). Latin species name ‘naevius’ means ‘varied’.
HABITAT: Dense humid coniferous forests.
DIET: Insects, earthworms, berries.
NESTING: Nest is built in a conifer. From three to five light blue eggs are laid, incubated by female. Both parents feed the young.
DISTRIBUTION: Breeding range includes British Columbia (except the coast), Yukon and Alaska. Year-round resident along the coasts of British Columbia and of northwest USA. Winters in western USA.

ON PEI: Does not breed on Prince Edward Island, sightings listed as ‘accidental’ (spring and winter) so far. See note below on bird vagrancy.
CONSERVATION: Numbers in steady decline, vulnerable to forests fragmentation. In spite of this, currently still not listed at risk.
NOTES: This species will establish – and aggressively defend – a territory around bird feeders.
Vagrancy: In biology this means an animal going way outside its normal range. For birds, this can happen when there are storms and they get blown off course. On other times, the bird simply wanders in a different direction than usual. Here’s an article about vagrancy in birds.
