Weekly Update: May 31 - June 7

Female Blue-winged Warbler by volunteern Don Johnston

We have hit the tail end of migration, with just a few stragglers left. Most of the migrants caught this week were females or second-year males, almost fat enough to continue their journey. Most of the birds have been the usual suspects, but there have been a couple of surprises. We had a Northern Rough-winged Swallow, and saw first-hand why it is so-named: the barbs on the outer primaries are stiff and hooked. Even rarer, we caught a female Blue-winged Warbler, a lifer for some of us!

Tommy Thompson is now bustling with baby American Robins, some of whom have wound up in our nets. More and more Yellow Warbler nests have been discovered, as well as Warbling Vireo and Northern Oriole nests. Also, after much sleuthing, a Song Sparrow nest was found – exciting because they are such difficult nests to find. The Tree Swallows are still brooding, and the Northern Rough-winged Swallows continue to investigate tail pipes! Two pairs of Spotted Sandpipers are nesting, and one of the nests was found with 4 eggs. Even as we wrap up banding, our dedicated volunteers will continue to find and monitor nests, documenting the birds that call Tommy Thompson Park home.
