[mou] Sibley County warblers

[rdunlap at gac.edu]

It seems that passerine migration is always a few days behind the twin  
cities along the MN River. Whereas most of the states' warbler species  
have been seen in the cities for almost a week now, we are just  
starting to see those species in places near Henderson and St. Peter,  
which leads me to suspect that the majority of warblers come up the  
Mississippi flyway and then some turn southwest and follow the  
Minnesota River upstream.

This afternoon at Rush River Park south of Henderson I found 16  
species of warbler:

Blue-winged
Golden-winged
Tennessee
Orange-crowned
Nashville
Yellow
Magnolia
Cape May
Yellow-rumped
Blackburnian
Pine
Blackpoll
Black-and-white
American Redstart
Ovenbird
Common Yellowthroat

The majority were definitely Yellow-rumped and Tennessee, but it was  
interesting to see good numbers of Blackpoll. Equally interesting were  
several Orange-crowned Warblers and a single Pine Warbler.
