The Squeaky-Clean Call of the Least Bell’s Vireo
Photo Credit: Maslowski, Steve, Public domain, via Wikimedia Commons “I hear you, but I can’t see you” are often the words going through my head when I am surveying riparian habitats amongst least Bell’s vireo (Vireo bellii pusillus; LBV). Vireos are small,...
It’s Rattlesnake Season in San Diego—What You Need to Know
A poll of my public speaking group several years ago revealed that for some of the group, snakes are their biggest fear (I guess for the rest it was public speaking, hence their membership in the group). This was very surprising to me, so I decided to try to educate...
The Sound of Silence

The Quino Test By Brian Lohstroh
There it goes! Did you miss it? That was the Quino Checkerspot Butterfly flight season gliding by. Better luck next time. This species has reached mythical status for me. I have a permit to survey for it, but over the past couple years, it seems like I never get a...
Ecology of a Superbloom
This spring is shaping up to be a great year for a wildflower superbloom. Superblooms are typically found in years of heavy rainfall and Southern California experienced its last superbloom in 2017. In our water limited ecosystem, it is common to associate superblooms...
Slugging through the Redwoods
Recently, my family and I took a vacation to the charming, coastal town of Mendocino in Northern California. We wanted a change of scenery and a change of pace and were delighted that this sliver of the state did not disappoint in either area. We will take away many...
