I do not see the Northern Harrier often and usually only when it is migrating through the area. The last time was two years ago. But, this was the first time that I have seen it actively chasing a raven.
There is a little irony in this observation f0r many ravens were hunting and eating fish along Kokanee Creek and its spawning channel. Suddenly the ravens were themselves being hunted. The harrier wasn’t interested in the fish, it wanted to catch and eat a raven.
A Northern Harrier eyes some ravens below.
The harrier gave chase. The result was not witnessed, as they all flew out of sight.
Dirk & I often enjoyed watching (especially, because they were soo noticeable) male adult harriers with their strongly contrasting white & black as they hunted low across fields, in eastern Oregon, when we lived there.
