We’ve been seeing a wren or two around here of late…actually we have some house wrens nesting nearby every year, but I can’t say I see the Carolina wren (pictured) until the colder months com. So are wrens good to have around? Well consider this…insects and spiders make up the bulk of their diet. Other common foods include caterpillars, moths, stick bugs, leafhoppers, beetles, grasshoppers, crickets, and cockroaches. Sounds pretty useful to me.
