FOS: Canada Warbler


Captain Sam's

Things picked up a little at Captain Sam's this morning, with 47 total birds caught, 45 of those new captures. We had plenty of warbler diversity, but the highlight was a beautiful hatch-year female Canada Warbler, a rare catch here. Despite breeding in northeastern United States and Canada, these birds don't pass through here in high volume on their way south, so this is just the third Canada Warbler we've caught. The other two were banded in 2012 and 2013.

It was a very nice morning at Little Bear with 47 new and 7 recaptured birds.  Our most common species of the day was the Northern Waterthrush, a warbler that has been having a particularly good year at KIBS.  Also stopping by the site were several Black-throated Blue Warblers.

Male Black-throated Blue Warblers, as their name suggests, are easily recognizable by their blue backside and black throat and face.  Females, while beautiful birds in their own right, have neither black throats nor blue backsides.  In fact, the sexes look so different that they were originally described as two different species!
