We have had a lot of Mourning Doves around the feeders this year. I have actively been stocking feeders for 2 1/2 years now and I have never seen as many juvenile Mourning Doves as I did this year.
My count was 4 pairs of adults and approximately 7 juveniles. Given that the average clutch size is 2 eggs, this would make sense.
