May Fourth
By this time one of your bird houses should be tenanted by a pair of house wrens. They migrate at night and the male arrives about a week in advance of his mate. Both birds assist in building the nest and in raising the young. As soon as the first brood has been reared, the lining of the nest is removed, and a new one built before the second set of six eggs is laid. Wrens may easily be tamed to take spiders and caterpillars (not the hairy ones) from the end of a stick and even from one's hand.
