Last year, we had a pair of mourning dove who actually surprised me one morning when I felt like someone was staring at me. I looked up and saw little beady eyes outside staring in.
They would sit on the outside air-handler unit and look in the window; spent a good part of spring and early summer in our company. That also is Caledonia's window she likes to look out, so obviously the doves would beat it when Cal'y showed up.
Anyway, it appears they have returned this year, for I looked up and there they were staring in like last year. Not the greatest photos as the window faces the sunrise, but proof the little beggars are real and I'm not making this odd behaviour up:
GRIN!
