Abstract: A total of 443 individuals of 19 species of birds was banded near Tlell, Haida Gwaii (Queen Charlotte Islands), British Columbia, between 30 August and 15 December 1997. Of the total birds banded, 355 (80.1%) were Dark-eyed Juncos (Junco hyemalis), whose numbers increased through midOctober, declined through November, and decreased abruptly in early December. One Dark-eyed Junco was recovered near the netting site four years later, on 11 November 2001. With the exception of 15 Hermit Thrushes (Catharus guttatus) and 24 Golden crowned Kinglets (Regulus satrapa), fewer than 10 individuals of the other species were banded, including two apparent vagrants, Yellow Warbler (Setophaga petechia) and Whitethroated Sparrow (Zonotrichia albicollis). Despite small sample sizes, the lack of recaptures of six species after mid October jibes with their known migratory status. Hermit Thrushes migrate later than Swainson’s Thrushes (Catharus ustulatus). Steller’s Jays (Cyanocitta stelleri) disappeared abruptly from the banding site after mid-October. Five species were recaptured and one species was observed 40 or more days after banding.
Key words: Dark-eyed Junco, Haida Gwaii, Junco hyemalis, landbirds, Queen Charlotte Islands, recaptures, site attachment, Tlell, timing of migration
