Oh yeah they can climb. We had one in a big knot this summer at the TOP of our martin house pole way up in the air, trying to figure out how to get up and over into the house when my husband shot the heck out of it with a high powered pellet rifle my son had left behind. Threw it out in the field and a couple of turkey vultures ate it the next day. RECYCLING! Just glad it didn't come after my chickens, which were a lot closer to the ground!
