Hmmm. Maybe a severe case of cabin fever?
Sunshine and blue skies should help as soon as the frost is gone. Warmer temperatures would also help!
I've been entertaining myself with hummingbirds--now that would be a great warm weather activity. Here's a picture of two eggs in a nest, but am not sure if these two are actually the ones that a rehabber has cared for since the mother disappeared.
The eggs hatched December 29 and today are out of the nest learning to fly in their enclosure. Here are some links if you would like to see this because after trying for almost an hour I can not get the video to load.
Feeding the two, Ana and Pavan:
You will be surprised at how their beaks grow longer and how quickly they mature.
