Migration Monitoring – October 16th-17th, 2007

October 17th

A fairly quiet day but one with an ominous tone. Despite the summer-like weather, with the temperature hitting 22C for a brief period before the rain started, another harbinger of winter made an appearance. A trio of Evening Grosbeaks descended upon the feeders and caused a ruckus. I’m not sure that this species has been previously banded at Ruthven because I could not find any prior records.

For the connoisseur, the bite of the Evening Grosbeak is much more unpleasant than that of the Rose-Breasted Grosbeak or Northern Cardinal.
