Census of terns and other colonial waterbirds along the Gulf of St. Lawrence coast of New Brunswick, 2005 / Andrew W. Boyne, Brad E. Toms and Julie McKnight. : CW69-5/467E-PDF

"In 1999, the Canadian Wildlife Service (CWS) started a program to census tern colonies in Atlantic Canada after recognising that many tern colonies had not been surveyed in over a decade and, for some, in as many as three decades. Since 1999, all four Atlantic Provinces have been surveyed every 4-5 years. The Gulf of St. Lawrence coast of New Brunswick was surveyed in 2000 and 2005 as part of this program; surveys focussed on Common Terns (Sterna hirundo), Great Black-backed Gulls (Larus marinus), HerringGulls (L. argentatus), Ring-billed Gulls (L. delawarensis), Double-crested Cormorants (Phalacrocorax auritus), Great Blue Herons (Ardea herodias) and Black-legged Kittiwakes (Rissa tridactyla). Surveys in 2000 and 2005 followed identical methodology and timing reflected peak breeding periods for Ring-billed Gulls, Herring Gulls, Great Black-backed Gulls, and Common Terns. ... This report summarizes the results of the 2005 surveys and relates the findings to data from previous surveys"--Introd., p. 3.
