Shorebird calls II : Plovers

Black-bellied Plovers with Semipalmated Plovers in the background, contact/flight calls (May, NJ).



Pluvialis plovers have two song types given in flight on the breeding grounds, wailing (also called territorial) and trilled. The trilled song is also given on the ground in aggressive interactions (Byrkjedal and Thompson).
