But I went there to see this:
In late November, I wrote about an interesting behavior — Bonaparte's Gulls pirating food from Sanderlings. I was intrigued enough by this behavior that I went back to watch some more. This time, the gulls were pirating food from Marbled Godwits.
Here's a series of shots as the gulls approached the godwits:
The gulls were fairly aggressive about it — running towards the godwits when it looked like they might have prey, vocalizing, and entering the "godwits' space." Several times I saw the godwits poke or chase the gulls away.
I'm not sure if all Bonaparte's Gulls do this, or if some individuals decide it's a productive way to obtain food. Later I checked Salmon Creek itself, and there were at least 30 Bonaparte's Gulls feeding along the shoreline there, without exhibiting pirating behavior. Or do individuals alternate between feeding strategies?
By the way, because there are so many Bonaparte's Gulls there right now (near the mouth of the Creek), and for some reason they're quite vocal, it's a great opportunity to listen to them and to learn their calls (perhaps I'll try to record them).
