Thanks to all who replied. Unfortunately my little nest of robins did not make it. I spotted a bird Friday evening that was spending a lot of time around the garage and it eased my mind. I left town Friday and immediately checked the nest when I arrived home just a few minutes ago. No adult birds were present at the nest or in the yard. All four babies were dead. I do not know what killed the adult on Friday. I have a feeling that the second bird may have met the same fate as I found a few feathers that appear to be those of a robin. Momma and papa birds get very busy feeding and sometimes let their guard down. It is sad to see this family destroyed before they even left the nest. Michelle King Blountville, TN Sullivan Co.
