Monday's Results

We banded 50 new birds and 4 recaptures of 5 different species.  Today is a good representation of what a typical mid-November banding day at KIBS is like - lots of Yellow-rumps with a smattering of sparrows and maybe 1 uncommon species thrown in.  Today's highlight was the Orange-crowned Warbler!  We have banded several Orange-crowns already this season but this is the first one that actually had an orange crown.  The presence of a large orange crown patch is more indicative of males however adult females can also have a small patch.  In fact it is possible that hatch-year females can sport a tiny orange patch.  The following bird was aged as a hatch-year based on the yellowish corners of the outer greater coverts and it was sexed as a male based on the large patch of orange feathers on top of its head.
