Clash of Species - Woodpeckers vs Snakes

WoodpeckerEarlier this spring, an oak tree across the street from our house attracted the attention of a pair of golden-fronted woodpeckers*. The tree's trunk has a hollowed-out place about twenty feet off the ground and the opening faces our front windows; I can see it from my usual seat in the living room.

Since April, MLB and I have watched as the woodpeckers made a home in the hollow trunk. They diligently climbed in and out of the hole in the tree, bringing out mouthfuls of dust and debris to clean out the space, presumably in preparation for a nest and young. They were constantly flying in and out and around the tree and we grew accustomed to them as neighbors.

Then, a week or so ago, I noticed an exceptionally busy flurry of activity. The birds were even more active in flying up to the hole in the trunk, stopping for a moment, then flying away. I noticed movement in the hole, and theorized that the adults were feeding a batch of newly hatched progeny in the nest.

I set up a video camera on a tripod behind a tree in our front yard, zoomed in on the hole, and started recording at around 6:00 p.m. I left it running while I went in for supper. The battery on the camera was good for only about an hour or so of recording, but I hoped that it would pick up something interesting in that short time.

Boy, did it ever!

Instead of piling several thousand words on you to describe what we viewed, here's a semi-short video (~13 minutes) distilling a couple of months' worth of action, leading to a completely unexpected climax.There are really three different storylines in the video; I hope you find it enlightening, if not entertaining.



So, if you're in the TL:DW mode, here's a quick summary:

  • Woodpeckers occupy hollow tree
  • They create a happy home
  • Said home is invaded by a rat snake
  • Outcome is negative for occupants of bird home
  • Turns out, there are actually TWO snakes in that tree
As I note in the video, we think the snakes are Texas rat snakes; their behavior and appearance are consistent with what we've been able to glean online. These snakes are non-venomous and non-aggressive. They are excellent climbers (duh) and seek out birds' nests for food. They will also eat rodents, including squirrels. As serpent neighbors go, we could do a lot worse.

The woodpeckers have relocated somewhere else in the neighborhood. I still hear their calls, but haven't seen them again. We enjoyed watching them, but also recognize that they are somewhat destructive birds so their absence is not personally devastating. We do hope, however, that what the snake dined on was eggs and not live young.

The snakes remained in the tree for a couple of days after the final video. We have additional footage of them climbing up and down the tree in search of more prey, much to the chagrin of a small bevy of tiny birds who were obviously disturbed by one of the snake's presence. However, we never spotted their nest(s) so we have no idea of the outcome of that confrontation.

For our timid neighbor's information -- that would be you, Kristi -- the snakes are now gone as well.

*For the longest time, I thought they were ladder-backed woodpeckers. But while researching the species for this article, I realized that the coloring and especially the call were wrong. So much for my career as an ornithologist.

Hi Eric,
I was directed to this post and your video by my friend Janet Hamilton. I believe she is your friend as well. I'm a Texas Master Naturalist and would love to share your video on our chapter's Facebook page. Would you mind? My TMN chapter does a lot of work in a local state forest where there is an endangered species of woodpecker. This particular species - Red Cockaded Woodpecker - is a specialist in that it only lives in forests of old growth pine trees with little under story brush. They choose old pines because they will have soft centers - easier to build their nest holes. And when they build their nest holes in pines, it causes sap to drain down the side of the tree. The sap prevents rat snakes from being able to enter their nests. Interesting adaption that apparently the species you've filmed here doesn't have. I think the other Master Naturalist in my chapter would find your video fascinating. May I have your permission to post it?

Eric,
Well done! Just like watching PBS Nature shows, but with a Texas accent for the narrator instead of an English accent. Sharla and I both watched and enjoyed.

Hi Eric, Janet just told me you answered. Doh! I forgot to refresh the page. Here is a youtube video on the Red Cockaded Woodpecker project. Part of the reason the RCW is endangered is because it's a specialist - meaning it will only live in old growth pine forests. Not many of those left so it's running out of appropriate habitat. Not unusual for non-specialist woodpeckers to use cavities that other species have created. Gotta tell you this is one fantastic video. Can't wait to share it on the Heartwood Chapter of Texas Master Naturalists Facebook page. Thanks again!!!!

Hi Eric!
I am so happy that I came across your fascinating video! Your article is so interesting and informative and I hope I will be included in your email list. I’m just sad that I didn’t know about this sooner. Merritt and I would love to be notified of any future Pecan Creek presentations. You and Debbie are an amazing, smart, fascinating, sweet and fun couple and we look forward to getting to know you both better when I am healed more completely.👍🙏👍. In the meantime, know that we both appreciate you so much.
Blessings to you and Debbie,
Diane & Merritt
