Hi all, I have a 15' - 20' tall 10" - 12" diameter trunk maple tree in my
yard and it's oozing dripping sap all over the place. I looked at the bark
and can see no splits or anything, seems to be just oozing out. We've had a
very wet, cold fall/winter here in west central NJ zone 6 I think. Not sure
what type of maple it is but it is, during summer, a very full healthy tree
with fairly large green leaves.

What's going on?

Humans aren't the only ones that know how tastey maple sap can be.

With oozing on the main trunk, look for a series of shallow holes all in a line.
This is the work of a woodpecker (yellow bellied sap-sucker). They make these
sap wells on a variety of trees. Maples are the only ones likely to 'bleed'
profusely from them, though.

Dripping from the tips of branches? Critters of some sort may have snapped
the tips of the branches. Squirrels will sometimes do this and come back to
drink the sap or eat the sap-sicles on cold mornings. Squirrels will even
chew the bark on the top of maple branches to get sap.
