Notes

  • S5672 - Pair estimates from the BNA account have been used (36,000 pairs; 573). This is a very minimal estimates as it is derived from early season surveys and does not cover the whole breeding range. Thus a total of 50,000 pairs which yield an estimate of 150,000 birds. Fall surveys in the St. Lawrence yielded 131 000 Surf Scoters (JPS unpublished data) and did not cover the maritimes. So about 200 000 to 250 000 Surf Scoters in eastern North America can be assumed.
  • S8153 - Estimates of population size are based on maximum counts from recent migration surveys and on fall surveys in the St. Lawrence which yielded 131,000 Surf Scoters (Savard, J-P. 2012 unpublished data) but did not cover the maritimes.
