So I will use this opportunity to clarify some of the reasoning behind t= he species list on the NSBS Spring First Arrivals table. http://www.nsbirdso= ciety.ca/library/resources/spring-first-arrivals The reason these species are not part of this NSBS dataset: We have excluded= species who have significant overwintering populations in some part of NS (= see Conclusion section below table), to reduce any entries that require assu= mptions on our part. For example, did those RB Gulls get blown in from a nea= rby wintering population? Or were the Lesser Black-backs (always a tongue tw= ister) ones already present in SW NS (probably not)? Even Baltimore Orioles g= ot nixed due to ambiguity.=20 NatureNS will be getting regular updates on Spring First Arrivals as the mig= ration season progresses.
