There was a recent ASCAList discussion on this. Here in N.A. we have
Sapsuckers (dunno if various woodpecker species do it) that make the
horizontal rows of holes. I may be mixing threads and critters, but I think
there was some mention that if the sap ferments and they come back for a
drink they may get drunk.

The internet and literature suggest they are sap-sucking rather than looking
