The Eastern Spadefoot, Scaphiopus holbrookii, is not a big anuran. It is adult at a length of about 2 inches, sometimes a bit smaller, sometimes a bit bigger. But for its size it does have a pretty-big voice. I’ve heard the vocalization likened to a burp. And at times it sounds like that to me. But I had to rethink the sounds of the spadefoot chorus being voiced in our flooded yard last July. Those calls reminded me more of abrupt purrs than of burps. But the calls apparently sounded just right to the females, for even before full darkness had fallen on that rainy day most males were amplexing visiting females. Even before morning light only the water and the eggs remained.

Our backyard used to be a railbed. Over the rails ran the local Gainesville to Gulf trains, a company now as extinct as the dodo. But the sunken bed, now devoid of rails, ties, and most spikes, remains, and at the lower end temporary flooding is common. We leave it as it is because the treefrogs, narrowmouths, and spadefoots breed there annually. These used to be called Eastern Spadefoot Toads, but today just Eastern Spadefoot will do. They are actually in an entirely different family than the toads. Eastern Spadefoots have almost smooth skin and tend to be a brownish color with a lyre shaped lighter dorsal marking. They have only a single digging spur (but they are very efficient and dedicated burrowers), lack or have very small parotoid glands, and have vertical pupils.

Now we’ll scoot ahead about 14 days. Some of the water had soaked in, but enough was left to allow several hundred tadpoles to grow and metamorphose into tiny spadefootlets. Our yard was temporarily untreadable as the hundreds of wee ones sought refuge well away from the railbed. To walk was to crush, so we kept to the front yard for a few days. But the inconvenience was well worthwhile, for now on humid summer and autumn nights the spadefoots, a burrowing species, emerge and seek repast. This is a cycle we and our neighbors enjoy.

An Eastern Spadefoots dorsal marking is in the shape of an hourglass.
