At beginning as well as 14 & 21 sec. Sing song whistle
This chorus of clicking sounds came from the wetlands at Calvert Cliffs State Park. I would guess a type of frog, but I can’t find any references to a frog that makes this sound in a search on the Internet. The wetland includes green frogs, turtles, and northern water snakes. Plenty of arrow arum, spatterdock, etc grow there, and there are fallen logs here and there.
