Finding out there is a wildlife rehabilitator in the county. I've been worried about a poor little goose with a hurt foot. Silly thing seemed to have forgotten he (she?) could fly back to the lake, and although it was only about 50 yards to the lake, he didn't seem to want to head there. I called the local shelter, who gave me his number. He came out yesterday afternoon, checked the goose over and felt that it would heal, but needed to be on the lake instead of trying to walk around. He very patiently herded the goose over there.
I didn't want it so far away from water, where it couldn't drink. There are plenty of bugs for it to munch, with it being summer, but it didn't have access to water on the neighbors' lawn.
