Last week I took a photography trip to the eastern Sierra to capture some spring time action over there. I went with a photographer friend to the south end of Mono Lake in hopes of a great sunset. Unfortunately, the skies were clear and the light was flat. Instead of a lasting sunset glow, it was as if someone just turned out the lights.

Fortunately, there were two pairs of osprey nesting near the shore in large nests built on top of two tufa towers. Just before dusk, the males came in close to the nests with fresh-caught fish. We had a brief show during which they perched on nearby tufa towers, enjoying their dinner, before they returned to the nests to deliver what was left to their respective mates.

During this time, the sun set and the light left. However, just before it got completely dark, I managed to get a shot of one of the males leaving the nest with the rest of the fish dinner. Because the sun was well over the horizon, it back lit the birds. I knew I could not get enough detail on the birds, so I underexposed and went with a full silhouette, emphasizing the graphical shape of the osprey taking off.

White-tailed Kite Attack

Occasionally raptors invade each others personal space, be it to encroach on their hunting ground or perch too close to a nest. They can engage in aerial battles, sometimes in dramatic fashion. Such was the scene I witnessed recently when a red-shouldered hawk perched on a tree, and a white-tailed kite didn’t like it very much.

I was alerted to the commotion by the screams of the kite, as it dive-bombed the hawk to drive it away from its perch. I was hand-holding my 100-400mm zoom lens at the moment, so I turned and ran straight toward the group of trees in order to get in better range. I didn’t worry about sneaking, because I figured both birds were probably too preoccupied to care about my approach.

The kite swooped down on the hawk about five or six times, each dive causing the hawk to fly straight up and wheel over upside down to avoid the kite (who was quite a bit smaller than the hawk). Finally, the hawk gave up the flew away over the horizon. The kite also disappeared from view, presumably to return to a nearby nest or favorite perch. As soon as the commotion began, all other birds in the area disappeared to let these two birds of prey battle it out alone. After the fight was over, the entire forest was eerily quiet.

An Ornery Curlew (Photo of the week)

Most of the time, many different avian species coexist in relative harmony, going about their business while generally ignoring one another. However, as this week’s photo can attest, there is occasionally some friction. I’m not sure what caused this curlew to snap at the gull, but there was quite a flurry of activity before the gull was chased off. It wasn’t until I reviewed the photos later that I saw the curlew defending his territory.
