  • Spring Is Here: Turkeys, Beetles, and Owls

    A little warmth brings out a lot of wildlife

    In the past week, temperatures have shifted upward dramatically. It’s above freezing every night, and plants and animals have responded appropriately. There is so much to see.

    We made a quick trip down to Bosque del Apache Wildlife Refuge near San Antonio, NM. The sandhill cranes are all gone, but there are plenty of ducks and songbirds. We stayed at a house near San Antonio, and were treated to a small group of wild turkeys. The females spent a lot of time foraging near the house, and a male would occasionally stop in and try to woo them.

    There were also a few mammals, such as javelinas and coyotes.

    We also came across an Eleodes, probably E. gracilis

    Back at the lab, spring is in full swing. Winter birds, like juncos and robins, have moved on, and summer residents, including lesser goldfinches and Say’s phoebes have settled in.

    Some of the year-round residents, such as western bluebirds (and, of course, screech owls) are taking their jobs as parents seriously.

    As added enticement, we replaced the old bluebird box with a shiny new one.

    Stink beetles are very much making their presence known. One can now find multiple species of Eleodes on a casual stroll around the neighborhood.

    Now that the weather has warmed up, this month’s pitfall trap survey was a bit more interesting.

    There’s plenty of traffic through the field with the traps, including this big, fuzzy coyote that strolled through the week before the traps were set.

    We caught a few Eleodes sponsa in the traps, along with wolf spiders, ants, and weevils.

    So the natural world has gone from quiet to extremely busy this month. Don’t forget to check out the updates on the owl cam page if you have a few minutes.

  • Owls Settling Down

    Terry’s owls are getting serious about the business of parenting. The female appears to have decided that five eggs are enough, and is incubating them full time. The male has been bringing her mice, and she has been dining in rather than leaving the box to eat them.

    Five eggs will be a pretty good brood if they all hatch and survive. For the next few weeks, she will be tending them, with the first egg expected to hatch about April 22.

  • New Feature: Owl Cam

    New Season of an Ongoing Project

    For several years, our neighbor Terry has been recording and posting footage from his camera inside a next box occupied by a pair of western screech owls. He has always had a strong following on Facebook, but for those of us who do not use the platform, he has offered to make the information and videos available here on the Lab web site.

    Once again, they have prepped the nest box and have started to lay eggs. The first video clips have been uploaded to Terry’s Owl Cam page, along with his comments and a spreadsheet of data regarding previous broods.

    New videos and commentary will be uploaded regularly, so stay tuned for plenty of drama and excitement. There are two eggs now, with more to come, and then it will be about another month before they hatch. Once the eggs hatch, there will be a festival of cuteness as the little fuzzballs eat and grow for roughly another month before they fledge.
