Bird tunnels



I'm not sure how these curious little tunnels form. I don't know if birds actually make them. But they sure know how to put them to good use.

We've seen wrens hopping along the paths, jumping up every now and then to grab a bug from the underside of the lip.



These are along the edge of an old logging road on our property. I've only seen them at the higher altitudes, where the ground is rockier.

If you know any more about how they're made, I'd love to hear it.

I'd planned that this post would describe a local political rally from the weekend, when we had not one, but two, presidential contenders in Birmingham. I'd have shown you lots of pictures, and related every little thrill. But I got sick, and can only relate how thrilling it was to watch it all on tv.

I have to say thanks to WBRC6, our local Fox channel, for showing both live. You can see the raw video of either appearance (Huckabee or Obama) by clicking on that link.

Too bad they don't show that huge honking anchor desk that they dragged all the way down to Bartow Arena for the reporters to sit behind.

We have these here too, a couple hundred miles east of you. I've thought of them as undercuts, mainly the products of erosion. We have them both on roadside, just beneath gullies, and along the banks of creeks.

And I've noticed that there are a lot of wrens that flit in and out of these places, too.

I suspect they may be used as runs by animals.

I guess that makes sense... erosion starts the whole process, and then critters expand things for their own purposes.

Oh I forgot to say, yeah I'd been thinking that too, about the animals using them for runs, since the tunnels seem so smooth.

I've never seen those before. Pretty interesting : )

It looks like mass wasting ... er ... slump.
