This bird has been wandering around our front yard all summer long. He is now well known by all the neighbors and enjoys a well-fed life of bread and crackers. But I am concerned if these birds are supposed to migrate in winter or can they survive in south Texas. Will he migrate eventually or will he try to survive winter by feeding off humans? Notice that he is also alone, no female companion. Sometimes he disappears for a few days, I wonder if he's got a family somewhere or is he alone. Also, do these birds fly or just walk? I appreciate any help. Thanks.
