It sounds like those birds think that you are a very good cook.
A squirrel feeder!!! Boy, that would not go over well, at my house. The squirrels here are very aggressive. They will go after any bird feeder, and destroy it, to get inside. I bought a metal, "squirrel proof" feeder; and, by the second day, they had figured how to get into it. When the bird feeders are empty, they hang from my deck railings, and chew on those. There are even nibble marks on the patio furniture (or Paddy O'Furniture, as the old joke goes).
Your story reminds me of a house we rented, in the North Carolina mountains, a couple of years ago. On the first morning, I awoke to the sound af a strange rapping moise. I went downstairs to find a male cardinal repeatedly flying into a livingroom window. After working on that window, for about 5 minutes, he moved onto the next window. Eventually, he did a complete circumnavigation of the house, spending time flying into each window. When he finished with the first floor windows, he moved up to the second floor, and started working on the bedroom windows.
The next day, I told the house's owner about the bird; and he responded, "Oh my! He's back! He has been doing this for 2 years."
