I had an incredible day of birding yesterday in the Blue Mountains near Troy, OR, and I'd like to share a couple of items.
First, at the first hints of daylight, at 5:45am, I stumbled onto a displaying Dusky Grouse. What an amazing way to start a day of birding. Here's a link to some photos and a video. Pardon the breathing, it was a steep hill.
I headed up to this area hoping to see a White-headed Woodpecker, I've found them there several times in the past. It turned out to be a five woodpecker day sans the white head! I had an incredible forty-five minutes observing two female Williamson's Woodpeckers chasing a male. Here's a link to a photo sequence of one of the females following the male into a tree, their interaction, and then he takes off again apparently enjoying being chased by two gals. Call me sexist, but it all seemed a bit backwards to me. Here's my question: After the male took off, the female in the tree didn't immediately follow him. she stayed for over a minute "sniffing" around the spot where the male had been (photo at end of album). Does the male have scent glands with which to leave scent markers? Was it pheromones? Or had he recently had something really good to eat?
