The Atlas of Breeding Birds of the Maritimes Provinces gives a Nova Scotia population of Belted Kingfishers of 4,100 +/- 1,600 pairs and a Nova Scotia population of American Robins of 370,000 +/- 130,000 pairs. If the above estimates you are referring to derive from BBS data then they are approximately 60% to high for kingfishers and 340% too high for robins. > > As far as the long term trend goes, you can go directly to the BBS > trend analysis page and have a look at the data.
