I took these 2 Maps from last year (left)
and this year (right) from Hummingbirds.net
site to compare.
Remember last year, how the temperature
rose between the 18th and the 22nd and the
hummers came up. Some must've been
trapped because it got a cold and we had
near 0 temp. for a good while after that
Anyway, my hummers got here a day earlier
last year compared to 2011.
