The melodic, robin-like warbling of Rose-breasted Grosbeak rings out through northern hardwoods and Appalachian oak forests from April to July. One of the common and striking birds of these forests, they are also favorites since they will sometimes become accustomed to feeders–and because the black, red, and white males are stunning. They winter in wetter forests of eastern Mexico and Central America and return north in spring when their habit of feeding on mulberries makes then easy to observe at Gulf Coast migrant traps.
The above animation shows their arrival on the Texas Coast. A classic trans-Gulf migrant, the onrush of Rose-breasted Grosbeaks is apparent and as a common and conspicuous migrant, birders can find them almost anywhere in the East in April and May. By June they have settled down in the breeding areas, which are mostly shown pretty well on the map. However, Rose-breasteds are common in the higher Appalachians. If you look carefully, you can see that he maps is showing them well into North Carolina, but this should probably be a bit more obvious since they are not rare in those mountains. Fall migration occurs in late August to October and is very striking on this animation, unlike the maps for secretive early migrants like Cerulean Warbler and Louisiana Waterthrush. For widespread and conspicuous species like this, these animated maps really show the picture of their migration well.
