The past two years we have had an unusually warm spring and early onset of
summer. I am not sure how much this influences the movement of Anna's
hummingbirds as they are relatively hardy when it comes to cold weather,
but they do seem to be expanding into new territories every year. Some of
them now winter over in parts of Alaska. I think it's exciting to watch
them migrate into new areas and climates. I think time will tell how
permanent they become in these harsher climates, but I don't think it's
premature to mention given how often it is occurring.
