This winter, Santa Clara Valley was lucky enough to see several groups of evening grosbeaks take up residence is a couple of predictable locations. Word quickly spread throughout the birding and bird photographer communities. This species is not very common for this area, so it was a first time bird for many who found them (including me!) The grosbeaks returned to the same general area day after day for several months, providing everyone with great viewing and photo opportunities.

These photographs were all taken on the same day on the grounds of a technology firm. (Even the technology parks of Silicon Valley have their share of wildlife!) This particular gross (yes, a group of grosbeaks is called a “gross”) had about 20 females and 3 males. They flew between a number of chinese pistache trees within the same area. Between the flurry of activity and the loud noise of nuts cracking in their beaks, they resembled a swarm of locusts, stripping one tree bare and then moving on to the next.

They would do just about anything to get at the tree’s food. It was amazing to watch them hang almost completely upside-down from a branch in order to reach the nuts. Here a female shows her perching skills.

Not to be outdone, the males could dangle just as well.

Overall, I spent about an hour following these birds from tree to tree. When I finally left, they seemed just as energetic as when I arrived. It was a treat to see this rarity, especially in such numbers.

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.

Cedar Waxwing (Photo of the week)

This weeks photo features the Cedar Waxwing, one of my favorite passerine species. I love the way this bird’s feather colors blend together into soft gradients, giving the appearance of a painting. Waxwings derive their name from bright red feathers near the tips of their wings, which is thought to resemble sealing wax. Cedar Waxwings travel in flocks and almost always perch off the ground, usually in trees, and rarely in bushes or shrubs.

The waxwings seen here descended on a row of cherry trees, and proceeded to eat with great gusto for about an hour, moving from tree to tree. All shots were taken hand-held with my 100-400mm zoom lens. This is a great walk-around lens, which I use on hikes if I’m expecting the possibility of seeing wildlife.

Earlier this month I was happy to get some nice views of a wintering palm warbler, while photographing in the city of Redwood Shores, CA. This is a somewhat uncommon bird for this area, so I was excited when I confirmed the sighting after further research. My view was unobstructed and the lighting perfect – about an hour after sunrise with the low, winter sun directly behind me.

I shot quickly and furiously, trying to capture as many poses as possible before the bird flew off. I ended up with about 45 seconds of time before the little guy decided he’d had enough with the paparazzi. The following photos were taken at the same time, in the same tree. Thank God for 8 frames per second!
