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.

Quite A Mouthful (Photo of the week)

This week’s photo features a brown pelican fishing. What impressed me about this photos is just how big the pelican’s throat pouch balloons underwater. Often we just see the head as it comes up full of water (and hopefully fish), but here we can see the bill before any water starts to drain. Brown pelicans often dive for their food, whereas other pelican species prefer to scoop prey just below the surface of the water. Once the bill is above water, it must drain before the pelican can swallow what’s left over. During this time, fish can sometimes be seen jumping out of the throat pouch for freedom. In addition, other birds sometimes take this opportunity to steal fish out of the pelican’s mouth.

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.

Northern Mockingbird (Photo of the week)

Recently I photographed a Northern Mockingbird perched on a berry bush. It appeared as if he was gorging himself on berries, stuffing one after another into his mouth. Soon after this feast, he flew from the bush to a nearby tree. He began working his mouth up and down, and to my surprise, a berry emerged from his mouth and into his beak, as seen in the photo below. After he ate one berry, he again worked his beak up and down, and a second berry emerged.

I realized that when I first saw the mockingbird chowing down on berries, he was actually stuffing them into his mouth for later consumption. I couldn’t find any notes about this behavior online, but it was quite a sight to see berry after berry magically appear in his beak. However, not every berry worked out so successfully, as can be seen in the photo below.
