Behaketaren xehetasunak
This was perhaps the largest colony I have ever seen in almost 40 years of studying this species throughout California. 20,000 was a low estimate and both Bob and I agreed that there could have been up to 40,000, as they were densely packed along the entire 2-mile canal. A few photos attached.
