Spring Birds of Ontario
Each Spring, millions of birds take to the southern sky as they wing their way north to Ontario. They fly alone, in pairs, in waves and flocks and in strict formations. The smaller songbirds fly at about 1000 m while the larger ducks and geese may be 3 km high as they cruise the Atlantic flyway. Birds migrate north by day and by night, sometimes both. Songbirds are mostly night flyers where the darkness offers protection from predators. But the bright lights of cities can be fatal attractions. The flights are gruelling and sanctuaries must be found for food and rest.
How do they find their way? We believe they navigate by the sun, the stars and the Earth’s magnetic field. Some navigate by recognizing landmarks below -rivers, lakes, shorelines and valleys. Some believe they have an internal barometer that keeps them at a steady altitude.
Hundreds of species of birds fly north to us each year. Here is a look at only a few of them.
