And all hibernation sequences were messed up by the ridiculous weather we had this fall/winter. A lot of bulb-dropping flowers already bloomed and died, a lot of butterflies/moths already pupated and died, a lot of migratory birds didn't migrate, and died, and a lot of hibernatory animals are finding themselves hungry and awake (as they ate their stashes when under a normal metabolism earlier in the warm portion of the season.

But everyone was so happy about the warm weather...
