What’s An Avostilt?

I’ll never forget when in 2003 I first heard the expression “Avostilt”. The San Diego County Bird Atlas needed images of Elegant Terns and author Phil Unitt introduced me to the biology team monitoring the tern colonies at the south end of San Diego Bay. Elegant Terns had recently colonized the narrow dams separating the … Read more

2017 June: Elf Owls In Riverside County

2017 June in Joshua Tree National Park

My trip to Joshua Tree National Park was not without its surprises. I promised to wait one month before speaking of one of them, but there is a good reason for the delay. I’m sure you’ll agree when I finally get permission to speak about it. My friend Sula found a seed pod in doing … Read more
