An Owl, a Squirrel, and a Cooper's Hawk

We spend quite a few early-morning hours on the hawkwatch platform. Because we spend so much time up there, we are able to see some interesting bird behavior. This time, we got pictures of it too. A Great Horned Owl flew past the platform, and it was carrying an unfortunate Eastern Gray Squirrel. Anna was able to get her camera in time to capture the events that followed.

Suddenly, we saw a Cooper's Hawk swoop in from behind the Great Horned Owl!

The Cooper's Hawk was calling as it chased the owl, and it dived at the owl several times.

The hawk continued to chase the owl into the forest behind the hawkwatch platform, and we heard the hawk calling for a few minutes after the birds had gone out of view. We don't know if the owl stole the squirrel from the Cooper's Hawk, or if the hawk was attempting to steal the squirrel from the owl. No matter what was going on, it was interesting raptor behavior to observe from the platform, and we are glad we have pictures of the event to share on the blog.

We have had an unusually high number of Ospreys flying over the hawkwatch platform for the month of November. On November 5th, forty-one migrating Ospreys were counted at the Kiptopeke Hawkwatch. That number exceeds the total number of Ospreys counted in the month of November at Kiptopeke in some previous years. 

There have also been days with good numbers of other migrating species.  There were nineteen Bald Eagles seen migrating over the hawkwatch platform on November 5th. On November 9th, we had a large flight of Northern Harriers. A total of forty-six Northern Harriers were counted from the hawkwatch platform on that day.

Some notable birds that were seen from the platform recently are the first Golden Eagle of the 2017 season on November 1st, a White-winged Dove being pursued by a Cooper's Hawk on November 4th, thousands of migrating American Robins on the morning of November 7th, and the first Tundra Swan flocks of the 2017 season on November 9th. As is often the case, these birds escaped our cameras. (The White-winged Dove also escaped the Cooper's Hawk.)  However, Yellow-rumped Warblers are currently very abundant at Kiptopeke, and we are able to get pictures of them when they visit us on the hawkwatch platform.

A notable person that stopped by the hawkwatch platform on November 7th was Scott McConnell. Scott was the CVWO Official Hawk Counter at the Kiptopeke Hawkwatch in 2006. We thank him for his visit to the hawkwatch platform.
