Rose-breasted Grosbeak —Ross Feldner Male Rose-breasted Grosbeaks are unmistakable with their graphic black and white plumage and brilliant rose-pink breast feathers. They get the “grosbeak” part of their name from the French term grosbec, meaning “large beak” and exhibit what is called sexual dimorphism meaning the male and female have very different plumage. They stay hidden for the most part, seeking shelter and food in leafy tree overstories but will visit feeders, streams and bird baths. Like many shy birds, the Rose-breasted Grosbeak is usually heard before seen with both male and female giving out a loud, distinctive “eek!” sounding call. Grosbeak’s nests are constructed in trees or shrubs and are made of loosely woven grass and twigs formed into cup-shapes. Generally 1 set of young is laid each year. Rose-breasted Grosbeaks will freeze and flick their tails when startled after which they give chase towards a threat. They are beneficial to farmers by eating potato beetles and weed seeds. | |
