Plus a lot of them 'migrate' along with the birds! You should see the array of different license plates driving around our city this time of year! When my nieces came to visit last February, they kept a log of how many different plates they saw, and I think they got all 12 from Canada and most of the States including Alaska and Hawaii, plus Puerto Rico.
We do have a little bit of weak sunshine getting through, but lots of clouds around today, too. Much warmer outside, though. Some of the orchid 'migrants' are getting put back out this morning.
