General Status Rank
Rank: 
Undetermined
Status Rank Description: 
Peripheral species from the west; very little known about this species in the Territories, may be breeding in the NWT; Overwintering of AMDI confirmed near Norman Wells, NT. Twenty records on ebird. BBS records and ebird records exist for the NWT, not enough records to discern a trend estimate for the species. Likely a small extent of breeding range in the south western portion of NWT.
