Contemplating Red-shouldered Hawks

The entrance to our humble birding patch is defined by a gate and chain-link fence. Royal Palms line both sides of the gravel road which leads to a wet prairies, woodlands and a lake:

This is the view looking back down the road before sunrise:

This past year our Homeowners Association planted hedges of Firebush (Hamelia patens), a most welcome innovation. Their blooms attract wintering hummingbirds and also butterflies such as this Zebra heliconian:

A roosting Red-shouldered Hawk strikes a characteristic pose. It appears to be deep in thought, with head gently bowed, chin to chest. Its mind must be so far off, meditating, contemplating its place in the order of nature? Might I startle it into awareness by touching its red shoulder?

Of course, this is far from the truth. The hawk is keenly aware of the surroundings. Sharp eyes are actually watching for any scant movement which might betray the presence of a prey item, whether insect, reptile, amphibian, small mammal or bird. Immobility and stealth are essential assets for a successful hunt.

Adult Red-shouldered Hawks vary from very colorful (as above) to rather pale. Those native to Florida tend to have a sun-bleached appearance, due to genetic variation rather than the effects of UV rays:

Immature Red-shouldered hawks also vary somewhat in the intensity of their streaked plumage, which they retain for about 18 months:

The red on the adults' shoulders shows up best in flight:

This juvenile Red-shouldered hawk exhibits a more useful identifying mark. The outer primaries are white at their base, creating a light band or "window" near its wingtips:

I usually hear and see one or more of this species on our morning walks in the local wetlands. This is a handsome adult bird:

They prefer wetland habitats, and their diet varies by location. Amphibians, reptiles and invertebrates comprise about three-quarters  of their prey in southern states, but studies in Quebec, Massachusetts, Wisconsin and Maryland have revealed a predominance of mammals. They also capture birds but are usually unsuccessful in such attempts.

One immature Red-shouldered Hawk currently favors an area along the entrance to our birding patch. It roosts in the tall Royal Palms along the sides of the road. Here it perches on a clump of the palm's fruit:

  7. Very interesting variations! Red-shouldered Hawks are quite uncommon in Ontario. Is that white one really the same species!?

  12. In answer to The Furry Gnome, there are four recognized subspecies--

    Buteo lineatus lineatus. Breeds in the eastern and midwestern U.S. and southeastern Canada is the largest subspecies, and generally the darkest in adult plumage.

    Buteo l. alleni. Breeds south of lineatus, into the northern half of Florida. Differs from nominate lineatus by smaller size and sometimes paler, gray head and back.

    Buteo l. extimus. Breeds in the southern half of Florida. Smaller and paler than either lineatus or alleni.

    Buteo l. elegans. Breeds in California and in Oregon west of the Cascade mountains. Differs from lineatus by smaller size, solid rufous breast, brighter
    rufous shoulder patch and barring on underparts, and wider, white tail bands.
