We found this little bird on the path between the cabins. It had trouble staying upright, couldn't hop or perch, and was a little twitchy. Because of its long bill and green feathers, we originally thought it was some sort of hummingbird, but eventually determined that it was too big. I posted pictures on FaceBook, which were shared by our nature-loving friends, and we found out that it was a juvenile red legged honeycreeper.
We put it in a bucket so it was away from drafts and fed it sugar water and squished papaya. Within a day, it was hopping around and eating on its own, with the favorite foods being papaya and very ripe banana. I made sure to keep the dogs in the house and just left it perched a table in the kitchen with a good supply of papaya, banana, and water. It didn't move much for a few days, and then started hopping around the table and sometimes fluttering to the floor. In about a week, its feathers had grown, and I went out one day to start lunch, and it was gone. We're pretty sure it flew the coop since no predators could get it in the kitchen, and we didn't find it fluttering around on the floor or outside the kitchen. Now we're keeping our eyes out for a tamer-than-usual honeycreeper, although they seem to like to stay higher in the trees, so it's likely we'll never see it again.
