The Timberwolf Ponds can be accessed on the left of Irish Rd. (just across from Richfield County Park), north of Coldwater Rd. in Richfield Township, Michigan.
I've watched this nesting pair for the better part of 8 years and have never seen this level of "tree trimming". The force needed to tear off a chunk of bark and wood was incredible. I was near to end of the my optical zoom for this one and the sun came through the trees at the perfect time.
