Is the mocker "eating" at the feeders or is doing the "dive-bomb" routine of a nesting mocker? If the latter, there is probably not much you can do, but move the feeders. If, however, the mocker could be drawn away with food, you could lure it away with raisins (a favorite with mockingbirds). It's just a guess, but I suspect this mockingbird is nesting close by... As for nesting this time of year, I'm no expert. I've never quite figured out just when immature plumaged mockingbirds should show up and where. My whiff on Bahama Mockingbird was in the Everglades in early April. It was a brownish-gray sub-adult Northern Mockingbird with streaking on the face and sides of the chest. The white wing patches and outer tail feathers were totally hidden from view on the bird at rest. I waited 15 minutes before the bird flew, removing all doubt about its identity. I wasn't expecting to find a *young* Northern Mockingbird the first weekend in April. Unfortunately, I never found the RBA reported Bahama Mockingbird, even though it was reported both before and after I was there... Sigh. -Greg Miller Lusby, MD
