While taking photos from my ground pod at Bolivar Flats, several hundred black skimmers were hanging out near the jetty. It was difficult to see what kind of birds were there until you hear them “barking”. They eventually lifted off and formed a cloud of skimmers, which is always cool to see.
Taken with Canon 1DX and Canon 500mm F4 IS II with 1.4X III teleconverter mounted on Skimmer ground pod with Wimberley II gimbal head
