Coyotes on the beach

As I was leaving St. George Island I saw two mature eagles diving in an aggressive manner. I thought I might be able to get some decent pictures even though it was foggy and cloudy. When I got the window down and my camera out of the truck I saw what they were harassing.

Here's what I saw through a 400MM lens. 

 

At this range and low light level, I couldn't be certain if the was coyote or coydog. After some serious cropping and brightening, here's what the eagles were chasing.

It's a fine, obviously well fed, black coyote! I don't know if it walked across the bridge (6 miles) or swam over, but it appears to have adapted well.
