Animal of the Month

Black Phoebe

 
The Black Phoebe, Sayornis nigricans, is a fairly small bird, growing up to 6 to 7 inches. Other than the underside, which is completely white, the rest of the bird's coloration is grey. It is a dapper flycatcher, meaning that they dart out to catch flying insects then return to their perch as quickly as they left. These birds are typically found near water in order to build their nests made of mud and can also be spotted under bridges and on ledges and overhangs. There have been instances where Black Phoebes have eaten and fed fish like minnows to their young. They are monogamous creatures, wherein couples can stay together for up to five years. In the relationship, the females call the shots. While the male Black Phoebes give the females tours of prospective nesting areas, the females ultimately chooses her favorite spot and builds the mud nest.

What's the Buzz?

In around November last year, we noticed a lot of activity around a Valley Oak tree. As there were a lot of leaves on the tree at that time, and we didn't feel it was safe to get too close, we assumed that it was a wasp nest. In late January, when the tree was bare, we got a closer look and discovered that it was actually a Honey Bee hive!

As it was well away from public trails, we left it alone, but today, we discovered that it has been abandoned, so I was able to get a better look at the hive. We typically find Honey Bees in cavities on trees, or even in the reclaimed water boxes, so it is unusual for us to get a close look at the structure.

The honeycomb looks to be empty, there are no caps on the cells and the wax feels dry to touch, not sticky as you might expect if honey was present.

We can't tell for sure why the hive has been abandoned, but we are hoping that the bees have just swarmed because they didn't feel secure in that location. There is also a possibility that the colony could have been affected by disease.

Breeding Pair of Red-Shouldered Hawks Return To Ulistac

 
Every year, for at least 7 years, a pair of Red-shouldered Hawks have been nesting at Ulistac. Most years they choose the same tree, and often re-use the same nest. Occasionally, they will try out a different tree nearby.

This year, they appear to have had had 2 babies, who are almost ready to fledge! Once they leave the nest, their parents will continue to feed them for several weeks until they are able to hunt for themselves.
