Restore Protect Conserve America's Wildlife Resources. Rose-Breasted Grosbeak (Hydymeles ludovicanus) The black and white male with his large triangular breast-patch of rose-red is one of the most beautiful of eastern birds. His mate is quite different, more like a large overgrown sparrow, buff with a much larger bill than any Sparrow has. The male's reputation as a singer lives up to his beauty. His song resembles the carolling of a Robin but is smoother, more melodious - one of the pleasantest bird songs to be heard in the June Woodlands. The nest is built from 6' to 20' from the ground, in a shrub or small tree. the three to five greenish eggs are spotted and blotched with brown. The Rose-breast is found in the summer east of the Rocky Mountains, from the central states north to central Manitoba and Southern Quebec. It migrates to southern Mexico and South America.
