More photos of Stubborn Thing's twins, Benazir and Ernesto:
Here's Mom and Dad visiting the nursery (Mom is on the left.) Most of the time Mom stays with the babies while Dad hangs out on the roof or on top of the bird feeder. Dad hates everyone and if you get too close to the nest will dive at your head (as the pup has discovered several times.)
The twins sit facing backward most of the time, huddled together and protected by Mom's tail feathers.
I'm still amazed at how quiet baby doves are. I'm on the porch for at least two or three hours a day (about three feet from the nest) and I've yet to hear them make a sound.
