Chris’ Eastern Screech Owl Nest Box Cam’ 2015

Established 2000

The 2015 eastern screech owl (Megascops asio, formerly Otus asio) nesting season has concluded in this urban Austin, Texas, nest box.

The views shown here were provided by one or more tiny monochrome video cameras that are sensitive to both visible and near-infrared light. During the day, the cameras "see" using the daylight that streams in through the entrance hole. At night, arrays of infrared illuminators take over from the sun. (Meet the nest box internals.)

These daily slideshows can be controlled from the keyboard, not just the on-screen buttons. The left and right arrows move through the images one at a time. The up and down arrows cause the images to advance automatically; the more you press those arrows, the faster or slower the show goes. The spacebar will pause or resume a slideshow. Don’t have arrow keys? Use the W, A, S and D keys, instead.

April 23 – Owlets 3 and 4 left the nest box. Owlet 3 headed over to the crepe myrtle that stands next to the nest box tree. Owlet 4 was still in the nest box tree, considering its options, when I had discontinue observing. In both cases the adult owls stayed nearby and watched the owlets carefully, singing to them.

As always, I wish I could keep tabs on the owlets indefinitely, but, instead, I have to let them go the night they leave the nest box, and merely hope I'll catch sight of them in the future.

Enjoy your new lives kids, and may they be good, long ones.

April 21 – Owlets 1 and 2 left the nest box shortly after sunset. Owlet 1 climbed high into the nest box tree and then made a flight to one of the large hackberry trees at the back of the yard, where the owlets always end-up sooner or later. Owlet 2 climbed to a less promising place in the nest box tree, and was considering trying to make the flight to one of the hackberrys, when one of its parents perched in a crepe myrtle tree adjacent to the nest box tree, and began calling to the owlet, who then changed direction and climbed into the upper branches of the crepe myrtle. So, both owlets made it to places of safety.

April 16 – Stacy D. has done a wonderful job of narrowing-down the dates and times of egg laying and hatching, and the table above has been updated accordingly.

Stacy, I can’t thank you enough for all of the work you put in – you”ve just saved me a heck of a lot of time, since I no longer have to start from scratch when I get around to going through the master image collections to assemble the final figures. Instead, I merely have to refine your figures. Thanks so much.

This Weird Year – The owls started earlier than usual this year. That was inconvenient in terms of preparations. Then there’s the matter of this page being AWOL for most of the nesting period. That was a result of a serious employment issue, which had a lot of consequences. Fortunately, that was resolved entirely for the better quite recently. So, I can at least offer you daily slideshows. Daily commentary takes a lot more work, as does running the live video feed, and I must admit that I’m not ready to take on those tasks just yet.

Also, my post office box for postcards has expired, probably due to some credit card fraud causing my bank to issue me a new card, and thereby preventing the auto-renewal from taking place. So, for now, don't bother with the postcards.

So, it’s been a rough time for me, but the good news is that the owls appear to be doing great. Take a look at the daily slideshows and see for yourself. And if you want to help me narrow down egg laying and hatching times, your help will be welcome.
