NORTHEASTERN MARITIME REGION /Richard S. Heil This wasthe year that winter largely passed us by in the Northeast. Decemberand early Januaryaveraged exceptionally mild and bare groundand open water were the rolerather than the exceptions.As a result,waterfowl and gullslingered in the northand inlandin good numbers,while passerinesapparently remained widely dispersed throughoutthe Region, rotbet than concentrating at feeders or in shel- teredthickets. It would be an understatementto say that mostboreal irruptiveswere scarce--many were virtually nonexistent. Threemajor storms did passthrough. The firsttwo, on January15- 16, andFebruary 6-7, resultedin snowin the northand interior, but precipitatedmostly as rain on the southeastern coastal plain. The big- geststorm of thewinter was a Nor'easter,accompanied by galeforce winds,February 11-12, that trekked up the coastdumping up to two feet of snowin somecoastal areas of southernNew England,and a foot of snow in Nova Scotia. Twoperiods of strongS-SW airflow in advanceof approachingcold fronts December 1-7, and December 24-25 resulted in a number of reversemigrants being discovered during or immediatelyfollowing theseweather patterns: The first brought Newfoundland its first provin- cialrecord for HouseWren, a Blue-grayGnatcatcher, and a Black-and- white Warbler;a TennesseeWarbler in Nova Scotia;a Black-throated for the innerBay of Fundy.
