Canada Goose Population Management at the Minneapolis-St. Paul International and Downtown St. Paul Airports
A Canada goose (Branta canadensis) control program was initiated at the Minneapolis-St. Paul International Airport (MSP) in 1984, and at the Downtown St. Paul Airport (STP) in 1994. Flightless geese >16 km from these airports were trapped (MSP 1,734; STP 1,397), neck-banded (MSP 1,047; STP 502),...
