I was out and about doing bird surveys yesterday and I got to watch an interesting interaction between a small falcon and a large woodpecker.

Here's an American kestrel, minding her own business, hovering and looking for mice with leaky bladders or whatever to eat.

There were lots of northern flickers moving through during my survey. Most tried to avoid predators. Multiple visits to Hawk Ridge during the hawk migration has taught me that at the end of the day, flickers have a body built for food that many hawks like to eat. I guess this flicker was feeling his Wheaties and went in to hassle the hovering kestrel, vengeance for fallen and eaten brethren?

After getting properly buzzed, the kestrel did an about face and went for the flicker. Both are about the same size and I think if the kestrel had been a Cooper's hawk that the flicker wouldn't have engaged in any mobbing shenanigans.

Again, these aren't the best shots in the world, I digiscoped them at 400 meters. But had fun watching the behavior. The birds chased each other for at least five minutes (could have been longer, but I had to move on to my next survey point), sometimes the flicker was chasing the kestrel and at other times, she was chasing the woodpecker. Periodically, both would perch on the same wire--sizing the other up?
