Threats

Threats

Threats are not well understood, but are thought to include: large-scale decline or some other change in populations of flying insects; increased mortality of adults and/or young due to climate perturbations; ssues on the wintering grounds and/or during migration (pesticides, habitat loss);high levels of inter-specific competition for nests with an invasive species (House Sparrow); high loads of ectoparasites that reduce nesting success; andhuman persecution (e.g., removal of nests from bridges and other structures).
Score: 
A

Intrinsic Vulnerability

Little human disturbance, threats to habitat in the NWT are thought to be low.Intrinsic Vulner = A (large declines)

Rank: 
At Risk
Status Rank Description: 
Rapid decline population trends in Canada, Not enough data to determine the trend for this species in the NWT. Widespread spread species with moderate population numbers.
S Rank: 
S2?
Decision Process Description: 
Drafted by Leslie Wakelyn and S. Carriere mostly based on printed material in 2000; Reviewed in 2005 by Craig Machtans and L. Armer - no change in status (sensitive); Modified to Secure based on comments from C Eckert and review of more recent trends (S Carriere- 2006).; Reviewed in 2010;no change; Assessed as threatened in Canada (COSEWIC 2013), modified to At Risk due to detailed assessment (2013); Reviewed by Emily Upham-Mills CWS in 2015,suggested change to secure, but remain at risk due to continental threats as defined in detailed assessment (S Carriere)
