Wildlife Wednesday: Birds Nesting in the Park
Spring is a time when flowers bloom, deciduous trees re-leaf, and the insects emerge from their winter hiding places. It’s also the time of year when we notice birds nesting and laying eggs. Today, during our hikes with students and birdwatchers, we noticed 3 sets of birds nesting in the park.
Eastern Screech Owls (Megascops asio) actually started nesting here in mid-winter, as they have for several years. Owls have to train their young to hunt, so they start the process of nesting earlier than other groups of birds, so they can spend more time getting them ready to live out in the world on their own. Our owls are most likely deep into the process of incubating eggs. Screech Owls are small, and a eat a wide variety of smaller animals (such as small snakes, lizards, birds, large insects, and spiders). In the evenings, you may hear them singing soft trills, whinnies, and less commonly, screeches, from the trees around the park.
They nest in tree cavities, like abandoned woodpecker holes and hollow branches. In our park, they raise their young in nest boxes, made specifically for them. We currently have 3 pairs of nesting Screech Owls in the park, and with 2-4 young per nest, we could end up with 12 young owlets fledging out this year!
Cooper’s Hawks (Accipiter cooperii) have been nesting in the park for 3 seasons now. These thin agile hawks, specialize in hunting other birds in wooded areas. You can often see them sitting on a tree branch, pulling apart and eating a White-winged Dove or an American Robin. They are also conspicuous by their call, a loud high pitched KEK KEK KEK KEK KEK KEK KEK echoing out through the canopy of the trees.
They start courting and mating in late winter, and construct their stick nest high in a tree in late winter/early spring. It appears that the Cooper’s Hawk pair in our park have finished their nest, and are now incubating eggs.
Finally… the Purple Martins (Progne subis) have returned to Russ Pitman Park! We did see a few, here and there, in mid-February, flying over the park, but this week we noticed them returning to the colonial Purple Martin house next to the playground. They appear to be entering the nest holes and setting up shop. So far we have seen 3 pairs of North America’s largest swallows here. Today (3/22) they were very active, fluttering above the South end of the park, singing and catching insects on the wing. Purple martins are active and able hunters of dragonflies, flying grasshoppers, and other insects that go high up into the air.
We invite you to come out, and look for all 3 species in the park. If you need help finding them, a helpful naturalist can give you direction.
Thanks, and see you soon!
