An Anniversary

Two years ago this morning, I saw an Ivory-billed Woodpecker. It’s my only certain sighting in over 15 years of searching. For new readers, I’ve had two others of which I am slightly less certain and another handful about which I’m a lot more skeptical. To honor the occasion, I’m going to repost my voice […]

According to the paper, which has not yet been peer reviewed: We have shown that the rate of sightings is the strongest indicator […]

Trip Report: June 7-11, 2017

This most recent trip was very snakey, meaning I nearly stepped on several – cottonmouths and timber rattlesnakes. In all my years of searching, I’ve seen six rattlers, three on the most recent trip.
