Distribution

(144-33)/164 = 0.68; Although common during the breeding season, there are few confirmed records of breeding in NWT (B004); ~75% of total NWT area. Range extent visually estimated from range map in "Distribution of birds in NWT & Nunavut: 2009 Review" (CWS).

Population

Population Size

88,550 goldeneye spp. in NWT in 2014 (data from 2014 USFWS waterfowl breeding surveys, strata 13-18 (W119 accessed Feb 6, 2015)). A large proportion of this population estimate would be COGO, but some BAGO would also be observed.

Density

dispersed breeder
Trends

Trends

relatively stable may be increasing in NWT from available estimated population data (R265)
Score: 
G
References:

Threats

Threats

potential over-hunting, habitat loss, pressures on population occur mainly outside NT/NU in southern breeding areas and wintering grounds
Score: 
C
References: 
H131

Intrinsic Vulnerability

Forestry and possibly pollution, development, global climate change ;pressures from loss of wetlands and deforestation is a problem in southern breeding areas.
