We're doing a little landscaping in the backyard. Today was the busiest day yet, with chainsaws, sod cutters, and wheelbarrows full of gravel and bark going back and forth in front of the feeders. To add insult to injury, this was my weekend to clean and disinfect the feeders. The birds didn't get a break all day. I figured it might upset them enough that we wouldn't see them for a few days, but much to my surprise, they came right back, not even an hour after the work stopped. I was even able to sit out there with my camera while they were feeding, snapping photos without disturbing them a bit. I'm thrilled at their current level of tolerance and trust!
