PIBO MIGRATION SUMMARY
October 1st – 10th, 2011
Migration continued apace into the first week of October although it was generally quiet throughout most of the coverage period with the exception of a few active mornings at the start of the month. Typically one of the busiest times of the season, migration at the Point from the 1st – 10th was casual compared to previous years. Here’s a brief summary of events:
There was a noticeable increase in activity on the census with 30 catharus thrushes recorded along with a variety of other species in small numbers – Blackpoll, Palm,, and Yellow–rumped Warblers, Swamp and Song Sparrows, some high–flying Tree Swallows, and a few Hawks and Falcons. Intermittent rain kept the nets closed.
Lots of birds in the area this morning and a nice variety of early and late migrants including eight warbler spp., a few lingering Red–eyed Vireos, six sparrows species, and increased numbers of kinglets (47 Golden–crowns and 25 Ruby crowns), 34 catharus thrushes (Swainson’s, Gray-cheeked and Hermit, including 19 banded Gray–cheeks), 39 Yellow–rumped Sparrows, and 48 White–throated Sparrows. Nine fall "firsts" were tallied including a banded Orange-crowned Warblers.
A wet and windy morning with just the census and some additional observations completed. Lots of Blue Jays (168) departing in groups from the tip and some kinglets, Yellow–rumps, and White–throats in the netting area, but not a lot of additional activity, with just twenty–eight species recorded by three staff and volunteers in 90–minutes of coverage.
Another substantial fall-out last night and a wide range of species (57) reported on the day including 4 raptor spp., a banded Eastern Wood–Pewee, 3 Blue–headed Vireos, both species of nuthatches, lots of kinglets (73 Golden–crowns), thrushes (22 banded), and eight warbler species, among others. A captured Fox Sparrow was new for the fall.
It was active again this morning on census but there were fewer birds in the netting area. Totals on the day included 15 Yellow–rumps and 3 Black–throated Blue Warblers observed along with ones-and-twos of five woodpecker species (including Red–headed), Red-breasted Nuthatches, creepers, Winter Wrens, kinglets, and a few thrushes. Five raptor spp. including a Peregrine.
It was warm (15° C) and calm this morning with not much bird news apart from a small contingent of Blue Jays, kinglets, some more thrushes, a few Yellow–rumps, and 2 Blue–headed Vireos. Cormorant numbers on census were down to sixty, but up to 500 gulls were found at the tip – mostly Ring–bills along with Herring and Great Black–blacked.
Just four birds captured today in four hours and not many migrants on census or in the netting area. Some Blue Jays (84) and Winter Wrens (9) along with small numbers of others – Hermit Thrush and Wood Thrush, waxwings and pipits, and a few sparrows – but generally not much activity on the day.
A mostly uneventful morning and not much to report – 34 species noted on the day during four hours of coverage.
A large group of Blue Jays (721) observed heading southwest off the tip during census and "official" fall-firsts for Horned Lark and Purple Finch.
Light southeast winds, 17° C at dawn, and a quiet morning after a festive PIBO Thanksgiving dinner with eighteen friends and family the night before. Although there were no Wild Turkey, 56 Canada Geese were noted on census along with small numbers of the following species: Sharp–shinned and Red-tailed Hawk, Killdeer, Blue Jay, both kinglet spp., robins and waxwings, and a few sparrows...
PIBO’s next migration summary will be posted shortly.
