For the 11th spring, the Okanagan Valley Goose Management Program is kicking off this week.
The program is a partnership between local governments, stretching between Osoyoos and Vernon, and uses egg addling to keep the Canada goose population growth at a reasonable rate.
The process of egg addling happens when the eggs are coated in a non-toxic corn oil, which prevents them from ever hatching.
By the time the adult goose figures this out, it's too late in the year to make more eggs.
Contractors are hired to find the nesting sites, and work to finish off the addling by the middle of May.
Officials estimate that there are currently about 2500 geese in the valley, and that the goose management program prevents population growth of about 10,000 birds.
Canada geese aren't actually native to the Okanagan - they were introduced about 50 years ago.
Along with the warm winters, the geese had no parents to guide them, meaning the birds never migrated south in the winter, which led to the need to bring in measures to control the population.
