We had a NASTY wind/rainstorm a while back that blew down a bird's nest off our gutters. John had seen Momma (?) Robin in a tizzy the next morning on the fence, so I went investigating and found one baby on the ground.
A little later, I went back out but couldn't find him/her but then I was startled by not one but TWO gaping mouths. They had the start of flight feathers but weren't quite ready to be on their own.
I was afraid to move them for fear Momma wouldn't come back (plus, I wasn't exactly sure WHERE I could put them) but I was also afraid something would get to them. I eventually moved them and their nest to our bedroom windowsill.
That ended up being a good, safe place for them and I had the added bonus of being able to watch Momma feed them. Eventually they were able to leave the nest and I swear there's a Robin or two that's a little braver than the others. :-D
