|Scientific Name:||Gavia adamsii|
|English Name:||Yellow-billed Loon|
|Provincial Status Summary|
|Date Status Assigned:||January 26, 2009|
|Date Last Reviewed:||March 05, 2015|
|Reasons:||Widespread although scattered in interior, low abundance but numbers are increasing, no known threats.|
|Range Extent:||FH = 20,000 to >2,500,000 square km|
|Range Extent Comments:||Found during all seasons along the outer and inner coasts and scattered throughout the interior (Campbell et al 1990).|
|Occurrences & Population|
|Number of Occurrences:||C = 21 - 80|
|Comments:||Found along inner and outer coasts and scattered throughout the interior (Campbell et al 1990).|
|Number of Occurrences with Good Viability / Ecological Integrity:||Rank Factor not assessed|
|Number of Occurrences Appropriately Protected & Managed:||U = Unknown|
|Population Size:||AC = 1 - 1,000 individuals|
|Comments:||Uncommon migrant; rare summer visitant and rare winter vistiant along the coast. Very rare in interior (Campbell et al 1990).|
|Threats (to population, occurrences, or area affected)|
|Degree of Threat:||Rank Factor not assessed|
|Trend (in population, range, area occupied, and/or condition of occurrences)|
|Short-Term Trend:||HI = Increase of >10%|
|Comments:||Nonbreeding range has been extending southward in W North America (especially in the last 2 decades). Prior to 1924, it was on the hypothetical list (Brooks and Swarth 1925) but is now seen in small numbers along the coast throughout the year (Campbell et al 1990).|
|Long-Term Trend:||Rank Factor not assessed|
|Intrinsic Vulnerability:||Rank Factor not assessed|
|Environmental Specificity:||Rank Factor not assessed|
|Other Rank Considerations:|
|Inventory Needs:||Inventory throughout interior (except Southern Interior) and northern half of province to look for additional occurrences where it is assumed to be present as well.|
