Migration update May 15

A brief update on the migration for Thursday, May 15. The winds shifted back around to the north last night, and most of the birds that were new arrivals on Wednesday seemed to stick around rather than leaving. Numbers near the lakeshore may have dropped somewhat, but numbers and variety were good at some of the spots a mile or two south of the lake (see my post from before IMBD weekend for suggestions about good places to go). For example, Kim Kaufman had several warbler species including Blackpoll and Orange-crowned, plus Scarlet Tanagers, Orchard Orioles, and Rose-breasted Grosbeaks, on the Gallagher Trail behind the BSBO nature center today. The winds are supposed to continue northerly through Thurday night and Friday May 16 before shifting around to the west-southwest on Friday evening. Even though the conditions won't be ideal, I expect there will be a good arrival of birds on Saturday, partly because there are still so many birds dammed up to the south of us. It's likely to rain a little on Saturday morning but the diversity of birds ought to be very good in spots near the lakeshore.
