Speaking of peeping, the real subject of this blog is spring peepers--the tiny tree frog Pseudacris crucifer, the common northern variety. Yesterday evening for the first time this spring, we heard spring peepers, a sure sign of spring. It was amazing that they emerged on the first day of spring. I don't ever remember that happening before, usually we start hearing them late in February or early March. They can take a little bit of freezing, but we generally don't get really cold weather or hard freezes once they emerge. I looked them up this morning and discovered they are called crucifer because they have a dark mark that forms an x on their backs and crucifer means cross bearing. It shouldn't be long now until we start finding tadpoles all over the place and in the meantime we can enjoy the spring singing.
