Sunday, it was so hot where I live in Benicia that the songbirds in my backyard, except for a feisty male Anna’s hummingbird that isn’t bothered by anything, spent most of the day chirping and flitting around inside the little cluster of three 40-foot redwoods in a corner on the yard. I say "inside" the redwoods because the branches create a big green room in the space between their trunks when you slip under them.
I was curious if the redwood room was actually cooler than the rest of my yard, so I slipped out the back door about 2 p.m. to take a look for myself. I brought along a thermometer to check the temp and laid it on one of the branches that was waving around in the room. It certainly felt a little cooler, and after about 5 minutes the thermometer told me why. It was six degrees cooler inside the redwood room than it was outside the trees.
People are always asking me where wild animals go when it gets too hot. Well, here’s one of the spots. Trees. They get up close to the trunks of trees so they can take advantage of the insulating qualities of the green branches.
