This girl looks coy with closed eyes but is probably acting. Carolina Wrens pair the year round and may be faithful to the same mate for years, up to a maximum recorded lifespan of 7 years. Great songsters for their size, we can watch them at close quarters as they are not so flighty as larger birds, provided we dont startle them.
They arent fussy about a nest site, which is usually in a cavity below shoulder height and sometimes in brush piles, which this untidy gardener provides abundantly. The nest is a woven dome of grass and stems with a softer lining and even fanciful decoration (aluminum foil, polythene, etc.).
After attaching an opaque plastic bottle to a tree I was glad to find a wrens nest inside. But after a fortnight it is still empty, probably a dummy made by a Carolina or House Wren. There are several explanations why they make dummy nests, but my favorite is that a wise male lets his wife choose the furnished home she prefers.
Both kinds of wren live in this yard, surprising since they are boisterous birds and similar habits make them competitors. (RG)
