A Westjet Airlines Boeing 737-700, flight WS-551 from Hamilton,ON to Calgary,AB (Canada), rolled out on runway 16 of Calgary’s International Airport, when the crew reported a dead bird on the runway.

A subsequent runway inspection recovered a dead perch, not a bird. NAV Canada’s Aerodrome Safety department concluded their report of June 30th: “this is the first recorded fish incursion in the history of Calgary International Airport”.

The report was updated on Jul 6th stating, that the initial reports of a dead perch of 1.5 pounds (perfect eating size) were unfounded as well as reports, that the fish may have been distributed by an airplane conducting water pickups. However, airside operations did indeed pick up remains of an unknown fish together with some feathers of an Osprey. Biologists categorized the incident as a bird strike. The Ospreys are known to fish in city streams.
