The two bluebird nesting boxes have had an interesting story this spring, sans bluebirds. The first couple to move in were a pair of Tree Swallows. They stayed only a few days and apparently neither apartment met their liking and they disappeared. As of Thursday, a male house wren (also a cavity dweller) has be very busy building a nest and sitting on top of the house, singing his melodic mating song, in an effort to attract a female. In reviewing the literature on house wrens, I discovered that the male builds only a partial nest, often many, and the female that selects him as a mate will finish it. Just as my hardcover edition of "Michigan Birds" stated, he has left a stick coming out of the hole, so as to further advertise for Ms. Wren to choose him. There is a Youtube video below that demonstrates nestbuilding and the beautiful song of this tiny fellow. Finishing up chores before I leave early Monday morning-housekeeping and one last yard cutting. The gardens are all doing well and the intermittent frost is finally done. The Oriental Poppies are just beginning to bloom and should be in full show when I get home.
