Book excerpt: The status of Great Blue Herons (Ardea herodias) breeding in the Maritime Provinces was studied as part of the National Heron Census (NHC) in 1979-82, when regional reports were published for all other parts of the species' Canadian range. That information from the Maritimes, with many other data from earlier and later periods, is summarized herein, including many details that were not presented in the Maritimes breeding bird atlas (Erskine 1992). These herons breed (or bred) in at least 34 of 36 counties in the region, and data now available confirm the preliminary estimate. Breeding numbers may have increased up to 1980, but probably were stable since then. Poorly standardized assessment of productivity produced a range of estimates of which the upper limit was somewhat lower than found by two intensive regional studies in the 1970s.
