I have been visiting the geese at my local park this summer, and i have become quite attached to this one that has puffy and swelled up cheeks. first, any ideas what may be wrong with him? he seems to be fine other wise just a swelled appearance. he is so friendly and he comes running to me when he sees me. the other day he ran up to me and pecked me up my arm, real gently, not biting, just light pecking. he did this twice. any one know what he was telling me? i have named him "puff"
