White-winged Triller

Click on image for call

White-winged Trillers are summer migrants. They have a strong preference for woodlands but may be seen passing through the suburbs in spring, or staying on in suitable habitat adjacent to the suburbs. They are quite vocal when they first arrive in about September. After peaking in November, numbers decrease and there is no second peak in autumn when the birds go north again.

High numbers of sightings in the first year of the survey included many pairs and larger groups from many sites. In the later years of the survey most of the very few records are isolated sightings of single birds. Although the first year may have been exceptional it is clear that numbers are declining.

Breeding records are also in decline, with all 10 records being from the first nine years of the survey. The breeding period appears to be short, with nesting from early November to late December and dependent young from late November to mid-February. R=81. BR=41.
