Today while walking on the Volunteers Green River Trail I watched a pair of Chickadees prepare a nest site. They had chosen a dead tree and were working in a hole about 5' off the ground. One bird would leave the hole with a wood chip in its beak while the second bird waited. When the bird left the hole the second bird would enter. They would fly about 20' away from the tree and drop the wood chip. It then flew back to the hole, peeked in and sat on a nearby branch to wait its turn. I watched for about 5 minutes and the pattern was the same. Fly off with a wood chip, go back for a peek, sit and wait. The bird would be inside the hold for a minute or less before leaving with a wood chip. It will be interesting to watch the activity over the next month.
New arrivals on the trail: Ruby Crowned Kinglet, Eastern Kingbird, Yellow Rump Warbler and Blue Headed Vireo.
