A pair of mourning doves built a nest in my hanging plant. Unfortunately, one of the birds flew into our glass window and died. The other mourning dove has remained on the nest non-stop as far as I can tell. He/She (I'm not sure) will let me get within 2 feet of the nest and won't move. Can this have any good outcome? From what I can see he/she is not leaving the nest to even eat. I cannot tell if there are eggs. He/She has been there about (2) weeks and the partner died probably 5 days ago? The one ran into the window during the afternoon so assuming that would be the female? Any advice? I feel so bad.
