Today, least bitterns began cooing on Greenport's North Bay at 5:15 A.M. Two hours later they'd all but quieted, but not before I counted at least eight distinct individuals cooing in unison. (There may have been more. And the two that I saw were both males.)
This is the third year that I've had least bitterns returning to this marsh. I don't know how long before I started looking the least bitterns used the North Bay for breeding, but I can't find any documentation that this is a known spot for them. Does anyone know how I can put the North Bay onto the bittern's breeding map? Who may I contact? By contrast, Hudson South Bay has no least bitterns, and oddly no marsh wrens either.
