EPISODE 74: Aerial Warfare

That is pretty much what it looks like when you have a smaller bird diving down on a larger bird. We flushed a Bald Eagle from its roost on the side of the river. Then out of the blue here comes a smaller bird and starts to harass the eagle. It was an aerial spectacle. We did not get a positive ID on the smaller bird but it was the size of a hawk or Crow. (EDIT: Bruce Atwell’s photo of the aerial warfare shows that a Swainsons Hawk is the attacker on the Bald Eagle.)

Of course the falcon and Bald Eagle were two of our better species of the day. We also found Pileated Woodpeckers, Green Kingfisher, Prothonotary Warblers and lots of Red-Eyed Vireos to round out our list of 36 species.

We have a long list of people who helped with the survey today. We had Joan Bishop, Lea and Duncan Charlton, Bruce and his son Eric, Glen Coleman, Roger Shaw, JT Stewart, Jim Burk, Ron Armbruster, Bob West, John Barr, and Dennis Breining. Thanks to all for your help today.
