of Grosbeaks nesting nearby. This male rose-breasted grosbeak was feeding this cowbird. The cowbird was sitting next to the RBGB, beating it's wings furiously, demanding food and the male obliged. Cowbirds are native birds, but are parasites. The females lay their eggs in other birds' nests and leave them to raise their young. The problem with this is that often the young cowbirds are more aggressive than the other young and outcompete them for food and other resources. This male was busy feeding this bird and we didn't see it feeding any other of it's offspring at the time. Since then we have seen the male feeding with two juvenile RBGBs. We have not see the cowbird/RBGB a second time.
