Note: Bird species that are normally here only in the summer, or on migration, but which occasionally overwinter here in small numbers, are listed on the Overwintering Species Page.

The following species visit Calgary in the winter months.  Some are common and others are rarely seen.  This list does not include accidentals (birds whose range does not include Calgary and which have been seen here only a few times) and does not include year-round birds.

Frequency:

• A = Abundant (Over 500)
• C = Common (101 to 500)
• FC = Fairly Common (26 to 100)
• S = Scarce (1-25)
• R = Rare – irregular occurrence, in low numbers, and not necessarily in every year
• E = Erratic – numbers fluctuate greatly from year to year
