Weekly Update: May 9 - 15

Baltimore Oriole by volunteer Zak Smith

Tommy Thompson is bustling with bird activity this week. With the addition of several species, the males are fiercely competing for air time. A moment doesn’t go by where we do not hear the song of a Yellow Warbler, Black-throated Green Warbler, or an American Redstart (just to name a few). We have also had great looks of Scarlet Tanagers and Baltimore Orioles showing off their brilliant plumage to the somewhat less enthusiastic females.

A pair of Barn Swallows have been busy building their nest, making frequent trips to the parking lot to gather mouthfuls of mud. Baltimore Orioles are also in the midst of weaving a nest in the very top of a cottonwood beside the sailing club. As usual, the House Wrens have been disrupting the neighbourhood since they moved to town. One was seen frantically tossing out nest material from the Tree Swallow’s nest box, but the swallows quickly put an end to that!

TTP has been catbird central, with 19 banded this week! Many of the White-throated Sparrows have moved on, and the ones that remain are so fat that is a wonder they can get off the ground. We are saying goodbye to the Hermit Thrushes and hello to Swainson’s. There are still a few Ruby-throated Kinglets lingering, all of them females. Many of them are on their way to the Boreal Forest, where the males will be eagerly awaiting their arrival. So many of the birds that pass through TTP are heading that way, and our migration monitoring provides a valuable snapshot of the populations of these Boreal birds, who are not so easily recorded in the desolate north.

Don’t forget that TTP is open to the public on holidays as well as weekends, so bring the family this Monday!
