Help for a cunninghamia

Saint Louis, MO(Zone 6a)

I have a cunninghamia lanceolata planted next to my deck.
By all appearances it has been thriving and is now ~20ft tall.
I noticed today it has several points where sap is running down the trunk.
It's too high for me to get a close look at the source on the trunk.
Is this just from some sort of sapsucking bird or is it a more ominous sign?
There's no other sign of ill health, at least nothing I've noticed.
Thanks for any info.

Looks like damage from a woodpecker-like bird (sapsuckers are in that clan), but hard to say for sure from just those two images.

Would you show an image of the whole tree? Surely you have a nice tall ladder to get out there in this wintry weather, to climb up and do closeup forensics.

C'mon, Weerobin - go for it.

OK, I ventured out in the dead of winter for a few more shots.
Actually, it's a beautiful winter day here today. Nice day to be out and about.
But, sorry, the fireman's ladder stays in the garage.
I don't want to get anywhere near to those lethal cunninghamia needles!
A couple shots of the whole tree from opposite sides. And one of a typical branch w/ cones.

The tree looks fine to me. My folks used to use aluminum plates on string to keep birds away from the garden.
