應該是美國常見的紅尾鷹 Red-tailed Hawk，香港沒有，要查美洲的鳥類圖鑑才可以找到。

學習拍鳥之餘也應學習辨認鳥種，可練習在本地拍攝，然後找鳥書按圖索驥，或者請教同好。

期待見到你的本地鳥照。 :)

The dark bar in the leading edge of the underwing is diagnostic. The undertail may not be red. The red tail is more obvious for perching adult birds.

Hi FC!

One of the most striking Red-tailed Hawk image I have seen, very good!
Western (light-morph) RTH.

Stunning!! ;D very nice capture... ;) But all of the light phase Red-Tailed Hawk pictures i have seen so far have white throat, could this be another race of Red-Tailed Hawk?? or is it just the different variable plumage like a lot of Common Buzzards?? ???...

The Sibley Guide has a very similar bird illustrated- it is a Western light adult and has a dark throat. Beautiful picture! Did you find American birds tame compared to Hong Kong? I am always amazed at how approachable they are- I've had Blue Jays eating out of may hand and chickadees landing on my hat. Any bird to try that here would probably be from a cage or soon in one! ::)

Hi all!

Red-tailed Hawk is a variable raptor, both geographicly and individualy. One usually distinguish between six light-morph forms (Eastern, Florida, Fuertes, Alaskan and Kriders) and three dark-morph forms (dark, dark intermediate, and rufous morphs)

Here is an Eastern adult to compare to FC excellent image:http://www.47custer.com/2004/rt_hawk011704/rt_hawk/2.htm

Notice that Western RTH generally are darker than Eastern, and besides having dark throats, they are more rufous on the underside and usually have a more obvious belly band and barred leg feathers.
