Thanks, Lee. What about possum? Thought we saw a possum
out side last night hobbling down the road.

maybe. i've never had possums bother my sunflowers, but if it
disappeared overnight rather than in the day...

What does a squirrel do with a 1 month old sunflower head
with no seeds?

they eat the base of the flower. yup, even without seeds.

How long does it take for a sunflower to get seeds after
the petals fall off?

well, the immature seeds are there before petal drop (before
the flower actually but they don't become actual seeds until
they're pollenated). i haven't paid much attention to length
from bloom to ripe seeds really because i grow them for the
birds & squirrels, but i think it's 5 or 6 weeks. could be
less, but the wildlife don't wait for them to ripen usually.

I'm thinking that one had a problem with aphids that did it
in.

mine get aphids & mildew they still make seeds though.
