The sound of thousands of cranes trumpeting across the sky on sunny days in the Skeena Region of Northern BC marks the unofficial beginning of spring.

This incredible bird is the sandhill crane. It is one of the largest flying birds in North America. After spending their winter down in the southern states and Mexico, they begin their journey north in March and by April they make it to the interior of British Columbia.

They fly in flocks and form a V while they are migrating (sometimes travelling 250 kilometres in a single flight). By the time they make it to the Skeena Region, they are entering the last hump of a long journey on their way to the Yukon and Northwest Territories.

This ancient bird is a symbol of spring for many British Columbians and when you hear their call (heard in the clip below), you can't help but stop and look up.

Wildlife biologist Sean Sharpe is familiar with the sandhill crane and has spent many springs enjoying their way through the Skeena Region.
