Hello. I’ve been watching a female House Sparrow all spring. She built her nest in a place that I knew my barn cats could reach, but she laid her eggs before I knew what was happening. She hatched her eggs just yesterday. Today I went to the barn to find the nest destroyed. One baby was laying on the ground in the midst of the destruction and my cat was eating mom. What can I do for the survivor? I gathered up nest pieces and placed them in a plastic container. I’ve given the baby some water mixed with mashed up worms via eye dropper. It is so young it barely has fluff on its head and is naked everywhere else.
