Just a quick question: what is the difference between a juvenile bird vs. an immature, for eBird reporting purposes and otherwise? I have seen young great horned owls here in our woods in Waukesha and was wondering if these should be considered juveniles or immatures? So when does an immature bird become a juvenile (or vice versa, if I have it reversed)? I also spent this weekend on Lake Kabetogama at Voyageurs National Park in far NE Minnesota. I wasn't willing/able to drag my companions into too much hiking/birding, but did manage to hike a couple of the trails. On the Echo Bay Trail just down the road from where we stayed I was treated to several gray jays, including at least 2 immature/juvenile birds. Neat to see, as the immatures/juveniles are entirely black, besides being quite vocal. I also find gray jays (and Steller's jays) to be a lot more approachable than, say blue jays. Always neat to see these big birds so up close. Was also neat to see a stuffed great gray owl and boreal owl at the visitors center, both of which I have yet to see in real life.
