![]() ![]() Natural camber (bend), and can be measured flattened or un-flattened. *Wing Chord is measured from from the wrist to the tip of the longest primary feather **Wing from Friedmann data assumed to be un-flattened wing chord. ![]() Western: mean 238.5 mm (211-285) Western Red-tailed Hawk Weight Western: mean 403.5 mm (370-430) Red-tailed Hawk Tail Length The data below were collected while we were doing research on Red-tailed Hawks. We have found (as have others) that Western Red-tailed Hawks have longer WingsĪnd Tails than Eastern birds (See data below).

On average, their lifespan is around 10-12 years, but they can live for well over 20 years in the wild, and have been known to reach almost 30 years of age in captivity.Data for length, wingspan and weight below (males and females combined) is from A Photographic Guide to North American Raptors Red-tailed hawks are monogamous birds and may bond for life, changing partners only when one bird dies. After they find a mate, they build a nest together from sticks in the highest branches of a tree or on a lofty cliff ledge. Typically, Red-tailed hawks reach sexual maturity from around 18 months, although they may not begin breeding until their third year. By six months, they’ve perfected the art of soaring flight and hunting and are ready to make their own way in the world.After leaving the nest, the fledglings remain close to their parents’ territory for around 10 weeks.After hatching, young Red-tailed hawks are tended and fed by both parents and remain in the nest for 42-46 days after hatching.Eyasses are born blind, and covered in white down.Both male and female Red-tailed hawks take turns to incubate their eggs for 28 days.What is the life cycle of a Red-tailed hawk? Read on to learn more about the typical lifespan of a Red-tailed hawk and discover why some die young, and others go on to live a significantly longer life. Research shows that up to 36% of Red-tails do not survive past the end of their first year. Whilst under some circumstances, Red-tailed hawks can live for two decades or more, many do not even make it as far as maturity. However, in captivity, the life expectancy of these opportunistic birds of prey commonly known as “chickenhawks” may be considerably higher. In the wild, free-ranging Red-tailed hawks can be expected to live for some 10-15 years or even longer. Below, we’ll be looking at how long Red-tailed hawks live for and how these environmental factors may affect their lifespan. Their diverse range of habitats includes both extremely harsh conditions with sparse landscapes and milder climates with more plentiful shelter and readily available sources of food. ![]() One of the most widespread birds of prey in North America, Red-tailed hawks can be found from Alaska and northern Canada, throughout the United States into Mexico, and further south into Central America.
