Truth be known it is more of a DURING dinner nap.
He was sitting there napping and licking his chops.
Then, every so often, he would wake up (almost) then lean
over and take a few sips. He let me get very close, but
his friend (mom?) was a little excited at one point.
I don't think I freaked them out too much though because
they came back later in the evening after leaving for a bit to
let me clean the feeder and make fresh food. He was watching,
because I barely had the feeder back up and he was on it
while I was still standing there.
The last time we had a hummer do this he was staking out the
back yard to raise a family. I'm not sure it is the right time
of year for that, but I'll be watching.
