About These Birds
Buse à queue rousse
The red-tailed hawk is the most widespread and common hawk in North America. Its screaming cry is so iconic that it is often dubbed over bald eagle footage in films and television. These adaptable raptors thrive in human-altered landscapes and are a familiar sight perched along highways.
Snowy Owl
The snowy owl is the heaviest North American owl and one of the most charismatic Arctic birds. Unlike most owls, it is largely diurnal, necessitated by the continuous daylight of Arctic summers. Snowy owl irruptions — periodic mass southward movements — are tied to lemming population cycles.
