I recently lost a large chunk of the contents of my hard drive, including many of the photos I intended to use for this blog. Most of them still exist, scattered over an old hard drive, several thumb drives, and at least three camera cards. My files were backed up, but not organized.
I’ve been slowly going through them all, occasionally finding something I forgot I had. Like this video version of the Spider vs. Anole photo!
Most of my wildlife photos came from one job. That job, in spite of allowing me a lot of time and access to wander around taking pictures, did have a goal: to find and document flatwoods salamanders on two state forests.
It had recently been discovered that the flatwoods salamander is actually two species, so recently that the current Petersen Field Guide to Reptiles and Amphibians still lists them as one species: Ambystoma cingulatum. A few years before I started the job, the populations west of the Apalachicola River were declared a separate species, the reticulated flatwoods salamander (Ambystoma bishopi). They were already rare as one species; this little offshoot was extremely rare. There were only about 36 known ponds where they had been found, and at many of those, none had been seen in years.
In the comments for last week’s cricket frog post, I mentioned that the cricket frog was not the smallest frog in Florida. Then, I completely neglected to say what the smallest frog was. So, here it is: the little grass frog. It’s related to the spring peeper, in the Pseudacris genus.
They are tiny. The frog pictured above is sitting on my raincoat, which doesn’t really give a good sense of scale. Here’s one on a square of ordinary velcro, and one on the palm of my hand:
Little grass frog, on velcro.
Little grass frog, on hand.
The little grass frog is another amphibian that breeds in ephemeral ponds, as well as other grassy-edged bodies of water. I’ve only ever seen two, and I spent a great deal of time in their habitat.
It’s not particularly rare; it’s just very hard to see. Put this little guy in some dead grass, and he would disappear. These, like literally hundreds of mole salamanders, ornate chorus frogs, and leopard frogs, were captured in an attempt to catch flatwoods salamanders (more about those next week). I’ve never seen one just hopping around on the ground. If you do, what luck! Take a picture. Preferably with an object for scale, because nobody will comprehend just how tiny it is without one.
Go to a pond in the southeast and walk along the muddy edge, and you’ll likely see tiny frogs leaping into the water ahead of you. You’ll rarely see the frog beforehand; the first hint of its existence will be a little splash. They launch themselves many times their body length, springing from the weeds into the water as if assisted by wings. From the opposite side of the pond, you’ll hear repeated clicks, like stones being struck together.
If you can find one sitting still long enough to get a good look, you’ll see that it’s about an inch long: a slender, long-legged creature, with bumpy skin and a triangle on the back of its head. It will be some combination of brown, black, green, and gold.
There are two species of cricket frogs: northern and southern. The northern species has slightly longer legs and a slightly more rounded snout, but they are otherwise very similar. They sometimes interbreed where their ranges overlap. (Those shown in this post are the southern species or hybrids of the two.) Between the two species, they cover most of the eastern half of the US.
The breeding season depends on the local climate; in Florida they may breed year-round, while in the northern edge of their range it’s limited to spring. Adults eat insects and spiders, while the tadpoles are vegetarians and feed on algae. The tadpoles are actually longer than the adults, if you include their tails, which are long, transparent, and often black-tipped. The black tip may be useful in confusing predators into grabbing for the tail instead of the body. This is good, because cricket frog tadpoles are eaten by just about everything else in the water — dragonfly larvae, salamanders, fish, snakes, other frogs… The lucky tadpoles which survive can take anywhere from 4 to 12 weeks to metamorphose into adults.
Rat snakes are some of the most frequently seen snakes in the US, but they still cause a lot of confusion and panic. They’re often mistaken for whatever venomous snake lives in the same area. They’re relatively large snakes, and they have an intimidating defensive posture, raising the fronts of their bodies above the ground. And they can have a slightly triangular head if you’re looking at it and thinking, is that triangular? I don’t know… maybe? Kinda. Better assume it’s venomous.
It’s not venomous. Rat snakes are harmless, unless you’re small enough for them to swallow. They can even be beneficial to humans, keeping the rodent population under control. On the other hand, they’re notorious for stealing chicken eggs, which they can swallow whole. And they can clear out an entire nest of baby birds. (If you put up birdhouses, it’s a good idea to add predator guards.)
They’re also skilled tree-climbers*. If you live in the United States, and you see a snake hanging out in a tree in your yard, or from the rafters in a barn, or perched calmly on top of your doorframe as you go to open the door, chances are pretty good that you have a rat snake.
Identifying them can get a little complicated. They come in different patterns and colors, depending on the region. In peninsular Florida, they’re yellow with dark stripes:
Elsewhere on the Gulf Coast, they’re gray or tan with darker patches, like the one pictured at the top of this post. And farther north, they’re black:
And to the west, you get this splotchy, stripey kind:
These are all the same species! At the edges of their regions, intergrade patterns are often found. The Atlantic coast has some olive-green ones, a mix of yellow and black. In the Piedmont, where I live, they’re mostly black but often have some faint markings.
Rat snakes are constrictors, like boas and pythons, but much smaller. A truly giant rat snake is about 7 feet long, and most adults are under 5 feet. Still, you could say they’re the closest thing the US has to pythons (except in the Everglades, where the Burmese python has become a pest).
They like abandoned buildings and other structures near humans, where the rats are plentiful. So if you see a big yellow, black, or brown snake hanging out in a tree or a hayloft, no need to panic. It’s probably just a rat snake going about its exterminator duties. Leave it alone, and enjoy fewer rats around your house.
Totally not a nature photo, but I thought I would share my favorite Xmas song, which is to say, one of only two I will listen to by choice. The other is Tim Minchin’s “White Wine in the Sun” which is the only one I’ve ever heard that reflects my experience of the holiday.
But this is the only one I listen to in months other than December, just because I like it.
A belated response to the Daily Press weekly photo challenge: Oops!
I am an utterly hopeless bird photographer. My camera is bad for it, but on top of that, I’m bad at it. The only birds I have ever successfully photographed have been at the beach, where there is tons of bright light and the birds are more or less standing still.
Any other bird? It looks semi-okay on my camera’s little screen, but then I get it onto my computer and, wow. What is that, even? Is that a bird? It just looks like a blurry, grainy, underexposed mess.
Some animals live their lives on a strict annual timetable. Migratory birds set off about the same time each year. Hibernating animals start stuffing themselves and building up insulation-fat at the same time. Many species have reproductive cycles that match the seasons.
Some are so predictable and noticeable that they can come to symbolize a season. When the sandhill cranes arrive at the lake near my parents’ house, it is fall. When I lived there, in northern Florida, the sight of a swallow-tailed kite drifting gracefully through the sky meant summer was arriving. I have always liked summer, even in Florida where many hate it, so a glimpse of a kite always made me smile, and not just because they are beautiful. Which they certainly are. I don’t have a good photo of one in flight, so here’s a video:
But long before I lived in Florida, I lived in a much colder place: northwestern Pennsylvania. That area gets a lot of snow, and while they’re used to it, everyone is pretty sick of it by March. The earliest signs of spring are important. Spring there is announced by two sounds: the calls of Canada geese flying north, and the deafening chorus of spring peepers from every creek and roadside ditch that isn’t frozen.
Not a nature photo. This is a response to the Daily Post’s photo challenge theme: Gathering.
This is a photo from the Moral Monday protests in Raleigh, NC last year. This protest was polite, organized, and huge. There were groups there supporting civil rights, labor unions, public education at all levels, immigration, environment, healthcare… you name the cause, the state government had damaged it.
There were poor elderly people from the middle of nowhere talking to young grad students. There were Christian, Jewish, Muslim, and Unitarian Universalist leaders on stage. There were people who normally wouldn’t necessarily dislike each other, but who would just never see one another in their everyday lives, holding hands and holding signs and cheering for each other’s causes. There were signs in English, Spanish, and Arabic. There may have been other languages.
You want to get a bunch of disparate people all working together? Give them a really awful governor.
