Status in the Checklist Area - Uncommon to rare
     
 
Information

A large and robust tern that is gull-like in some ways. Produces a loud scratchy yelp fairly often. Encountered in our checklist area either over or near the Fraser River where is is seen annually flying back and forth during the summer months. This speices has expanded its population from more southern latitudes on the Pacific Coast. While limited breeding has been detected in BC to date, colonies nest to the south as near as Washington State. Caspian Terns have one of the longest periods of feeding fledged young. Adults will feed their young for 5 - 7 months after the young takes flight. They breed for the first time usually at 4 or 5 years of age.
