I have 4 male Rose Breasted Grosbeaks coming to my feeder. They can't resist the black oil sunflower seeds. These birds are migrating thru to nest further north. Very handsome birds. Another grosbeak that everybody is familiar with is our Cardinal...cousins to the Rose Breasted Grosbeak. For some reason, I have not seen any females, maybe they are already up north waiting for the "boys" to show up!
