Подробности наблюдения

Spotted from observation platform. Flew up as a group from a grassy area and landed straight out from platform . I could not figure out what they were until I saw the black spot on their lower bellies, brown/black on top and long black bill. When they flew up again I caught them on Merlin. Will post sound recording when I get home. Need to see if any mobile phone pics were good enough to post. https://youtu.be/34S-WnJCCHY?feature=shared
