Do juvenile American Robins migrate?
I was wondering if anybody here knows if American robin juvenile birds ever migrate? We ended up raising an orphaned robin fledgling. We also left the fledgling at a rehab for a week as it was sneezing a lot. In a week it was ready to be released so we decided to release it in the same neighborhood it was born. After releasing it kept visiting us but it's sneezing continued. Upon research I figured vitamin A deficiency in birds can cause sneezing and one way was to feed birds fruits like apple, grapes, mango etc. I offered grapes anytime it visited us as it never showed interest in any other fruit. Not sure if it was vitamin A or something else but it stopped sneezing and I was very happy. At this time the bird is a juvenile and use to eat grapes from my hand (may/June timeframe in northern Virginia). However it did not visit daily. It use to skip a day or two but would show up, until one day an adult robin attacked it. It seemed like a territory thing. After that the juvenile robin only visited twice. Last time I saw it, it just seemed very uncomfortable and kept looking around as it ate grapes from me. I'm confused if it just joined a flock or if it started it migration or if it was scared and chased away? I see a lot of other robins now in my backyard but all of them seem to be adult robins. Some come to me the min I start talking or whistling. None comfortable to eat from my hand. I sometimes wonder if one of them is my juvenile. It's just been 3 weeks and I doubt the juveniles will develop orange shade this soon. Any thoughts to help me understand more about these beautiful birds?
