©Bert Gildart: Here in Arizona at the Sonoran Desert Museum, the sound of spring is in the air. All around the state bird is creating a familiar sound that some say resembles the churn of a battery that won’t start. Others say the song contains a “clattering roll” and consists of “a series of quick beats without melody.” Whatever description fits the bill it is one now being heard virtually everywhere: from the tops of the mighty saguaro, from the thickets of the dense chain cholla, from the spiny top of the prickly pear…
The sound is associated with the cactus wren, a colorful species in which the male and female work together to build nests. Nests are huge and built so that the top is closed. When completed the nest will look like a football oriented vertically. But unlike many species, access to the nest is from the side; and that’s for a very good reason. It’s an evolutionary thing that helps obscure the wren from predators flying overhead. Those that were exposed, perished, and with time, only cactus wrens that created nest with holes in the sides survived.
Eventually, nests built by the pair may number several, perhaps even three or four. But after our bird couple has completed the nest, which one calls the shots? Who decides which nest will serve to raise their young?
L to R: Nests, which may number as many as four, are constructed together by both males and female. Nests could be prickly pear, in saguaro cactus, or deep in a thorn-filled cholla. Nests are constructed from a variety of materials.
Apparently it’s like newlyweds shopping for their first home. Final selection of the “nest” devolves to the female; she calls the shots!
As I say, it’s spring down here but what does that mean? It means that the high today approached 80. But tomorrow, if it rains (as is predicted), temperatures may not even reach into the 70s. Nevertheless, I’ve been told that despite such frigid temperatures, nest building will continue, and we can still expect to hear the song of the cactus wren.
We’re grateful to be surrounded by nature.
