I've got a mockingbird that comes and asks for food every morning. The cardinals and titmice will fly up to the tree outside the window and wait as soon as I open the window, but the mockingbird will sit on the tray on the window and stare at me until I open it. When I do, he'll wait in the tree, but as soon as I put the meal worms down, he'll come back and start chowing down. Doesn't seem to mind being within an arms reach of me at the open window. Never makes a sound though. Not while I can see him around the feeder at least. Working from home with the window/feeder right next to my desk is pretty nice. You get to see the different temperaments and "personalities" of the various birds pretty quick. Sometimes even within the same species; e.g., most of the male cardinals are a bit aggressive, and chase other smaller birds away if they get too close, but a new young male that started coming recently is considerably more timid, and gets pushed around by most of the other sparrows and wrens. The red-bellied woodpecker that likes to make machine-gun noises on my gutters every day, however, does get a little tiresome.
