Chickadees and flickers take to the home-made box and, sometimes the little screech owl occupies one of the man-made residences.
He makes a worthy tenant, for as a mouser, he is superior to the house cat.
Robin Red Breast is another easily attracted native bird. Last year I put up a robin shelf, similar to the ones shown in the following drawings, and inside of fifteen minutes Mr. and Mrs. Robin had hired the apartment for the season and were soon busily engaged in weaving the nest within fifteen feet of where we were observing them.
The Bluebirds.
The eastern bluebird is a common inhabitant of all States east of the Rocky Mountains from the Gulf of Mexico to Southern Canada.
In the Mississippi Valley it winters as far north as Southern Illinois, and in the East as far as Pennsylvania. It is one of the earliest northern migrants and everywhere is hailed as a harbinger of spring.
Fig. 3. Chickadee Feeding.
Domestic in habits, it frequents orchards and gardens and builds close to human habitations.
Fig. [1] shows a bluebird at the entrance to an artificially hollowed tree trunk, feeding its young. Fig. [2] shows another bluebird about to enter a bird box.
