Need Mourning Dove Help!

by Urban Mom
(Philadelphia, PA, USA)

I think we have a mourning dove mom and baby in our urban yard. The patio is all cement and the baby has been on the ground. the mom comes and goes. She watches me watch the baby but seems to feel okay with me. I am worried that the baby may be sick. How long do they stay on the ground? She has taken the baby out of the yard once for a day and then brought her back. I don't know how to help them. City living doesn't seem to be good for the birds. I have a photo of them - does anyone know if this is a mourning dove? Or what kind of bird it may be? Thanks so much!!
