Yesterday evening I got to go to the top of the lake in El Charco, the nature preserve and botanical garden just above San Miguel. Here, every evening, Cowbirds form rolling and weaving murmurations as they come home for the evening roost in the trees on a small island in the lake. While relatively humble as murmurations go, it is still an inspiring sight. I am not sure why they are called Cowbirds. Next time perhaps we will bring a cow and find out.
