There is a nice warbler hotspot on an island in Rondeau Bay that usually gives us at least one bird we haven't ween in the yard each fall.
This time it was a palm warbler moving rapidly on the ground and in some bushes.
The Palm Warbler is found in two different forms. Birds that breed in the western part of the range are duller, and have whitish bellies. Those breeding in the eastern part of the range are entirely yellow underneath.
