Despite another blustery day we managed to band our 1,000th bird of the season early this morning. The milestone bird turned out to be an after-hatch-year female Yellow Warbler that Chris pulled out of net 12 seconds before a Sharp-shinned Hawk hit the net (unfortunately the hawk bounced out before Chris could get to it). The high winds meant that we couldn’t open all the nets and we ended up closing down for good an hour early. With slightly under half our full net hours we, not surprisingly, finished the morning with just 11 birds banded.
Though activity was low, the morning was not without it’s highlights. A flock of 16 Black Swifts whirled about high overhead just before I set off on census, and Chris heard a solitary Solitary Sandpiper fly over. A stunning male Townsend’s Warbler was following a small flock of Yellow-rumps and the Lewis’ Woodpecker is still present, hawking grasshoppers like their going out of style.
As is tradition on August 31 I will include here a brief mid-season report.
A few species, especially the frugivores, seem to have had bumper breeding seasons over the summer. Western Tanager (19) and American Robin (32) both have had record numbers banded and juvenile Swainson’s Thrush (191) in particular dominated our nets early on. Out of the first 140 Swainson’s Thrush we banded this season, just 10 were adults. We are also having above average numbers of Warbling Vireos (179) and Common Yellowthroats (127). On the flip side, all the early migrating warbler species, with the exception of Common Yellowthroat, are well below average. This includes Yellow and MacGillivray’s Warblers, Northern Waterthrush and American Redstart.
In general migration seems to be 1-2 weeks early this year. Warbling Vireos usually peak in the third or fourth week of August. This year they made their big push Aug. 11-17. Common Yellowthroats, which are normally at their most abundant in weeks 4-5, peaked during week 3.
