Progress update on Cottonwoods:

The score? Woodpeckers - (at least) 6; Cottonwood - 0

I've been doing some yardwork this morning (raked and filled one big can, cleaned the pool, picked up citrus, etc.) and have been sweating bullets.  But I've been able to come inside and cool off between stints.  They are still out there working.  At least I have been bringing them LOTS of water to drink.
