Marsh bird and Colonial nesting Surveys
In this third year of participating in the national effort to survey for marsh birds (rails, bitterns, moorhens, pied-billed grebes, american coots) and colonial nesting (double-crested cormorants, great blue herons) the selected sites are showing early trends that will become more apparent after 8-10 years.
Note: the last survey is most indicative of breeding. Earlier dates can be breeders and migrants.
