Are There Beavers in Milam County?

It turns out, the answer is yes, though I am sure many of you already know that. I went on a great adventure on Friday with my fellow Master Naturalist to see for ourselves. We escaped to the wilderness known as her property outside of Cameron and searched for a rumored beaver dam on the spring-fed creek that runs through the land. It was a beautiful warm day for exploring. (Note that I am not providing the exact location to maintain the beavers’ and property owner’s privacy.)

Proof that it was a beautiful day in Milam County

We got into the truck and took off for the spring-fed creek that runs from the property to Big Elm Creek. At first we looked in the wrong place and got attacked by much greenbrier and dewberry vines that tried very hard to trip us (I later determined that I got a tick on my head – darn nature). I did determine that the water was not out of its banks and was very clean.

My friend called the folks who’d been on the property monitoring their deer lease or something, and they redirected us upstream. There we found what appeared to be weird flat areas with brown vegetation.

The brown stuff was actually duckweed on a big ole beaver pond! To say I was excited would be an understatement. The dog was also excited and immediately went swimming.

I enjoyed investigating the dam construction and listening to the water trickling through the spillways. It’s hard to believe animals can do this, even though I read a book all about beavers recently (and I highly recommend it to any fellow nature lover).

*Also they build a lot of tunnels. Here is an entrance.*

We found trees that had been gnawed by beavers (some from the previous dam a few years back). There were also trees whose bark had been gnawed. This definitely points to beavers!

We moved upstream some more and found a second dam, which has created a magical pond full of fish, butterflies, and plants. One of the things beavers do is provide an environment for wetland plants, increasing diversity and creating more fertile soil after the dams are abandoned. It was hard to pull myself away from the tranquility.

I wanted to see if there was a third dam below the first one we found. Sure enough, following the cool beaver trails led to another one that my friend thinks is a reconstruction of the original dam.

Since we had time and a truck, we went off exploring other parts of the property, which are mostly hay fields. We stopped and got to see a spectacular Northern Harrier fly right in front of us when we both had our binoculars. They’re beautiful hawks with a white patch just above their tail.

We then explored a ravine that lead to the big creek and observed how the creek is slowly moving northward. I did not fall down when I clambered down the embankment. I held onto trees.

*You can see where the creek used to be closer to the embankment*

We ended our exciting afternoon doing some more birding back by my friend’s house and enjoying each other’s photos. I’m so pleased to cross another mammal off my list of Milam County sightings, even if I didn’t see an actual beaver. All my beaver knowledge really helped me see the signs of them. I’m sure the beavers are glad the prowling humans and dogs are gone!

Little Brown Spiders

The wolf spider world never shuts down in Texas if you know where to look. About a dozen species from a number of genera mature over winter when they can hide among fallen leaves. They can be quite active at night during rare warm spells. They all look generally similar and are often hard to tell apart unless you know exactly what details to look for.

Here we have the obscure S. perplexa, which I’ve written about before. Turn it over and the white on black abdomen pattern makes identification easy. This is a juvenile male just one molt away from adulthood.

The other is Varacosa avara. I had found some a couple of weeks earlier and speculated they were this species mostly because of the strongly pinched carapace medial band at the posterior lateral eyes. This time it was another adult male, and I was able to confirm it from the spine lengths on the underside of tibia I thanks to a better image. The pinched medial band is a lot easier to see than the translucent spines, but the medial band pinching isn’t mentioned in the literature. Body lengths of both spiders are a little over 8 mm (a third of an inch).

Also seen was a much larger Tigrosa georgicola. The presumed female has been in about the same place for over a month. Previously she had retreated into her burrow as I approached but this time she held her ground. I didn’t attempt to capture her for photos since I already have a lot of photos of that species.

New and Unusual Wolf Spider Observations

Here are two spiders I’ve recently observed in my quest to identify all Texas wolf spiders

Do wolf spiders intentionally lie on their backs?

Yes! Here a juvenile Hogna baltimorina does just that while subduing a moth it captured a
second earlier and just seconds after I finished photographing it. It has all legs free to hang on to the moth. After the struggle ended, the spider quickly flipped over, prey and all.

The spider was released later and took its dinner with it.

A few years back I saw a wolf spider pounce on a grasshopper about the same size. The grasshopper jumped a couple of feet into the air, taking the spider with it. The grasshopper immediately made a much smaller second jump with the spider still hanging on. Then it was all over.

Moral of the story: If you meet a really big wolf spider, don’t try wrestling with it. You won’t win.

New Hogna Species Spotted

For years I’ve been trying to sort out the various Pardosa species in Texas. There are over a dozen of them and many are very difficult to tell apart by either appearance or genitalia. One common species in Texas appears to be a more southern species (Mexico and Central America), and the species it’s supposed to be is actually many miles east Texas. Others have sketchy ranges or none at all. It would be easy for an unnamed species to be hiding in Texas but I’ve been avoiding this possibility, which could seriously complicate an already messy situation.

Well apparently here’s one that is fortunately different enough from others to not be confused with them. It also has the most shocking appearance of any. There are at least 5 details besides pattern boldness that set it apart from others. Ostensibly it’s in the lapidicina species group which is known for its evenly banded legs, at least as juveniles and females. They also love rocks of all sizes and often sun on them. Steep clay slopes will do in a pinch.

I’ll be working with a professor at UT on this. I was visiting his ranch surveying wolf spiders and these just popped up out of nowhere. I’ve been working on that genus for years with only middling success but instantly knew this was something that was different than anything I’d seen in Texas in person or on iNat. Funding for domestic taxnomic research is scarce, so being able to interest professors in that area is important.

A First for Me

I went home for lunch on Monday and was nicely surprised by a first sighting for me. A Northern Flicker was drinking out of my birdbath. I did not know what it was, so I worked on some photos to put on iNaturalist. I had to take them from inside my house through a window, so they aren’t perfect, but they’re clear.

It’s considered a woodpecker, but it has dappled brown feathers with a red spot on neck and black markings. An it’s unique from other woodpeckers because it hunts its prey on the ground. Flickers prefer ants! This explains why it’s in my backyard. Fifty percent of its diet is ants. It also lets the ants crawl on it to rid it of parasites. I have an ant problem. Plenty for it to eat. Another difference from most woodpeckers is that it migrates. It can’t find ants in frozen ground.

I looked to see if anyone else in Milam County had reported one, and I saw the only other one was Michelle Lopez in 2024. She first heard it with her Merlin then she got some photos.

I really enjoy finding new sightings. When I tried to get to a better window to take photos it flew away. I hope it comes back and eats lots of ants.

Geeking Out over Sound Patterns

[I wrote this for my personal blog but accidentally created it on this site, so enjoy my fascination.]

Bear in mind that I have been looking at waveforms most of my adult life, so this stuff interests me. I still edit myself talking a lot (yep, it’s my job), so I know when I’m gasping or clicking from saliva before I even listen. It’s interesting, not that fun.

But it’s only in the past couple of years, since I e had Merlin Bird ID that I’ve been able to identify bird calls by how they look on a spectrogram.

Loggerhead Shrike – you can just tell it’s loud and harsh, not melodic.

This kind of knowledge is helpful in winter when there are so many sparrows around. Their spectrograms look different. Here’s one I also like.

Songbird recordings look very different. Some are more horizontal lines going up or down with the pitch. Others have a mix of tones, but you can see the melody. These two I got from Merlin, of birds I’ve heard.

As I’ve been enjoying the sounds birds, there have been other sounds Merlin catches, like loud trucks, airplanes, and wind. And, of course there are insects. I was being deafened by the sounds of late-summer cicadas when I looked down at the waveforms. Wow!

You can practically feel the pulsing by looking at those fascinating shapes. On the other hand, crickets just stick to one note.

So if anyone ever asks me how I know a sound is a cricket versus a cicada, I can turn on Merlin. It may not ID it, but I can now from the shape.

Here’s a sound I’m glad Merlin heard: a Yellow-headed Blackbird. They only show up here a few days a year during migration. Photo by Dorian Anderson.

I used to have some frog images but I can’t find them. I’ll be paying attention and when I hear something interesting, I’ll stop the recording, since Merlin doesn’t save recordings over about 20 minutes long, due to storage constraints. My phone would be FULL.
