Migration Monitoring – May 14th, 2008

The weather front that ultimately ended in rain this afternoon brought with it a number of migrants that made for a busy time in the banding lab. Although it was not possible to perform a census, a respectable total of 61 species were still encountered. Flocks of Yellow and Magnolia Warblers were in evidence while the mewing of Grey Catbirds was ever-present. New species for the year were Tennessee Warbler, Wilson’s Warbler, and Black-Billed Cuckoo. Even a few late Common Loons were observed first thing in the morning.

Visitor / Bander interaction reached an all time high today at Ruthven Park as I was hand fed chocolates in an effort to bribe me to keep me producing colourful migrants from the bags twitching on the hooks. I encourage everyone to emulate this latest development.
