ROSE-BREASTED GROSBEAK (Hedymeles ludovicianus) From the throat of this beautifully plumed bird is poured forth in the lush of the May morning so sweet a song that lucky is he who hears it. This bird frequents the second growth and thickets of small trees and bushes in overgrown fields. Of inestimable value is its service to man, for it consumes large numbers of tent-cater- pillars, gypsy and brown-tail moths, canker worms, potato beetles and many other harmful insects. The nest is in low trees and bushes and is made of twigs and lined with fine rootlets. The eggs, which number four or five are pale blue and heavily blotched with brown. The Rose-breasted Grosbeak is found breeding in south- ern Canada and in the northern United States east of the Great Plains. FOR THE GOOD OF ALL, DO NOT DESTROY THE BIRDS. LITHO, IN U. S. A.
