"The Peregrine Falcon ..." Province of Alberta Warnings Or Dangers Tip by Shara.Buchan

 
 

<p> The Peregrine Falcon </p>
<p> Status: Endangered throughout Canada. Populations in southern Canada were established with captive-bred young and remain small. Twenty years ago there were no breeding pairs in southern Alberta. Now there are 30 pairs across the province. </p>
<p> Appearance: Slim birds with a small head and long, thin, pointed wings. Similar in size to crows.</p>
<p> Food: Peregrines can reach speeds close to 320 km-h in a downward dive. They use their speed and agility to catch birds in mid-air. Their prey range in size from sparrows to large waterfowl such as ducks. </p>
<p> Breeding: In Alberta, they nest on ledges on steep cliff faces or high office towers. A male will fly complex courtship flights for his mate. In mid-May females usually lay four eggs. Both adults help incubate the eggs which hatch in mid-June. The young birds begin to fly 35-45 days later. Due to their inexperience flying and hunting, over 60 per cent will die before the next spring. </p>
<p> Lifespan: Up to 13 years. A falcon named Arrow nested and bred in Edmonton's AGT Tower for 11 years. </p>
<p> Risk factors: Agricultural and industrial use of pesticides has caused a worldwide decline of peregrine falcons. Pesticide use is closely regulated in Canada and the U.S. but not in Latin America where peregrines winter. </p>
