Do Red-shouldered Hawks Feed on Beavers?

This is a late post but recently work colleague, Shawn Good, shared with me images of a Red-shouldered Hawk he took with a digital trail camera on his property in Pittsford, Vermont.  He used a  beaver carcass for bait expecting to document the usual wildlife that might be expected in the local area: bear (bottom photo), coyote, bobcat, fisher and the like.  But he certainly did not anticipate a hawk.  The middle photo has been cropped to provide a little closer view of the bird. 

I did not think Red-shouldered Hawks typically fed on carrion, so I looked into several information sources on the web including the Peregrine Fund and saw that small mammals, reptiles and amphibians, birds and insects are the staple of the hawk's diet with no mention of carrion.  Considering the date the photos were taken, March 26, I will speculate that the beaver carcass was a welcome meal after a migration flight and that the usual food items might be in short supply or at least more challenging to capture in early spring.   So I guess the answer to the question is yes under certain circumstances.

Common Teal at Herrick's Cove

Sunday, April 11, 2010. While scanning a flock of 44 Green-winged Teal Anas crecca carolinensis this morning at Herrick's Cove (mouth of Williams River in Rockingham, VT) to my surprise I sighted a mature male Common Teal Anas c. crecca. This is the second year in a row that I have had the Eurasian or nominate race at this location, and this is the third sighting for Herrick's Cove within the past four years. The 2007 bird was a first state record of the subspecies in VT. All sightings have occurred in April. The drakes were putting on a nice show of courtship behavior. Below are a few digiscoped images of this year's bird.
