Looking Up!

The smallest Eastern Screech owlet is interested in what’s up.

These feathery bobble-heads are growing at a remarkable pace. At sundown, their parents visit, usually with moths, geckos, or worms (at least I think they’re worms…) as delectable nibbles for these cuties. While I don’t watch the camera overnight, I’m sure that feeding goes on throughout the dark hours. Often in the mornings, there is one, or more, deceased prey in the box, ready for a daytime meal when the chicks are peckish.

I haven’t taken daily photos to chart their growth, but they’re big and active now and it won’t be too long before they fledge. I’m fascinated with their daily activities, even when the three are lumped-up in a pile of fluffiness, breathing rhythmically.

Mom and Dad stay close by, coming into the box only to feed. Mom is always stationed just outside the entry hole.

Last year, the owls’ nest box was raided in late February, most likely by a Grey Fox or a Raccoon. This year, to prevent a predator from climbing up the tree and snatching the eggs or chicks, we wrapped the tree with linoleum flooring that comes from a roll, cut to size specification, at your neighborhood big box store. We nailed the width of the flooring to the trunk when mom owl had settled in the box to raise a family.

The tree isn’t near our roof or another large tree, so there’s no concern about a predator climbing up an adjoining structure, then lumbering over to this tree to gain access to the nest box. This makeshift collar has a thick linoleum coating which would be difficult-to-impossible for claws of a smaller mammal to penetrate for vertical traction, thus preventing successful climbing. Grey Foxes can jump up to 6 feet in height, so we placed the bottom edge of the collar at about 3.5 feet, the top edge reaches just over 7 feet high.

The collar looks a little goofy, and no doubt the tree is embarrassed by its attached swath of fake wood, but the fix is temporary and has provided some safety from predators for this owl family. It’s nearly 7 weeks since the the egg holding the oldest owlet (most likely the one on the left in the photo) was laid. Soon, these owlets will see their big, new world for the first time.

Owlets!

Fluffy, feathery, floofy owlets have hatched! Two were born on Sunday, the third on Monday. Tiny and fragile, they’re covered with fine, white down; it’s hard to believe that these helpless little creatures will grow into fierce hunters.

Mama’s tail feathers fill the top of the photo. The dark splotch just below are the remains of a bird or rat–I can’t quite tell; food tends to shift around a bit. You’ll notice the scattering of feathers amoung the nesting material.

Uptown Girl is an attentive parent and Shy Guy is now perched in the oak tree, very near the nest box. His job is to protect the nestbox and hunt for his family. He’s delivered a couple of rats and at least one bird, (sob, I think it was a Carolina Wren), as meals for mama and babies. Eastern Screech Owls enjoy a varied diet, which is one reason why they’re so successful in urban areas. Meals range from insects to earthworms, toads and frogs, rodents and birds.

In the weeks that the female was in the nest box awaiting her bundles of joy, she slept quite a bit. Now, she’s more active, with nearly non-stop feeding and cleaning of the chicks. She and the chicks do have some quiet, restful moments throughout the day and often, the chicks are nestled under mama’s warm, feathered body. When the chicks are awake, I’m enjoying their peep-peep songs, such sweet little sounds, though probably indication hunger. Mama continues to trill during the day.

Early in the mornings (about 6AM) when I first check the owl cam, she’s not usually in the box, though she typically returns shortly afterward. Just before sundown, she goes out, but only briefly. As the chicks grow, her absences from the box will become longer and more frequent, as she’ll also hunt; it’ll take two adults to feed these hungry, growing chicks.

It feels weirdly invasive to watch these beautiful animals in their intimate family life, but it’s fascinating to observe the preparation for and parenting of their offspring. Though a few days since the segue from eggs to chicks, the chicks have grown and in a month’s time, they’ll fledge. Their development, supervised by their parents’ excellent training, will continue in more natural settings, less observable by human eyes.

Critter B & B

With a new camera installed and functional, we’ve recently observed our Eastern Screech Owl nest box host a variety of critters, some that we didn’t want to see in the box.

Even with the cuteness of two little rats curled up together, the view of them snoozing away in the nest box did not thrill us. So, after they vacated, we closed the box for a few days.

After we reopened the nest box for business, other rats, or maybe the same ones–they all look alike to me–have come and gone over these past few weeks. Fortunately, none hung around for any length of time. 

Then, it was the rat relatives who nosed in for some naps,

…and private time away from noisy neighborhood Blue Jays. 

For the last week, in the wee early morning hours, just at sunrise, I’ve witnessed an Eastern Screech Owl, Megascops asio swoop to the box for inspection. She’d perch at the entrance hole, sit a bit, then climb in for a look-see. Usually, she flew back to a neighbor’s tree to spend her day. Today, she climbed in and stayed in the box for the day.

I’m not sure she’s thrilled with my oohing and aahing but she didn’t dart back into the box out of fear or annoyance, only lazily turned to look at me, squinting in the cheery afternoon sun. I’m glad she’s not threatened by my presence. 

I’m pretty sure this is the same female that we’ve hosted in the box for the last few years. She loves to be outside, perched in trees, even after the sunrise. I call her Uptown Girl. Her mate is Shy Guy and so far, I haven’t seen him. These two have successfully brooded chicks for the past two to three years. Last year, shortly before the eggs were to hatch, the nest box was raided, probably by a fox. After they abandoned our box, I discovered that they’d settled in a neighbor’s tree. I watched for several weeks and was rewarded by watching two fledglings learn to fly successfully under the careful tutelage of their parents. I hope they survived summer and have found their own territory and mates, ready to raise families.

It’s never a sure thing that the owls will stick around, or be safe. A juvenile Great Horned Owl has been in our neighborhood this winter and raccoons and foxes are always a danger to eggs and nestlings. I wish this female and her mate good things in their future.
