A hobby is a fairly small, very swift falcon with long, narrow wings.
There are four birds called hobby, and some others which, although termed falcon, are very similar. All specialise in being superb aerialists.
The "typical" hobbies are traditionally considered a subgenus Hypotriorchis due to their similar morphology:
- they have ample amounts of dark slaty grey in their plumage;
- the malar (cheek) area is black and
- the underside usually has lengthwise black streaks.
- The tails are all-dark or have only slight bands (White et al. 1994).
Species / Taxonomy
Monophyly of Hypotriorchis is supported by DNA sequence data, though the exact limits of the group are still uncertain. The hobbies seem to be one of the Falco lineages which emerged around the Miocene-Pliocene boundary some 8-5 million years ago and subsequently radiated - in this case throughout the Old World. Their relationship to the Peregrine Falcon group and the kestrels is not well resolved, however; taxa like the Red-footed Falcon appear in some respects intermediate between the kestrels and the typical hobbies.
- Eurasian Hobby (Falco subbuteo), also known as the Northern Hobby.
- African Hobby (Falco cuvierii).
- Oriental Hobby (Falco severus).
- Australian Hobby or Little Falcon (Falco longipennis) is uncommon but widespread in Australia. During the southern winter, some birds migrate to the north of the continent or to the islands of South-east Asia.
- Sooty Falcon (Falco concolor) of the North African desert.
- Eleonora's Falcon (Falco eleonorae) occupies the Mediterranean area during the northern summer, and migrates south to Madagascar for the southern summer.
The following species are tentatively placed here:
- Karearea or New Zealand Falcon (Falco novaeseelandiae).
- Brown Falcon ( Falco berigora)
- Taita Falcon (Falco fasciinucha)
Diet / Feeding
Although they will take prey on the ground if the opportunity presents itself, most prey is caught on the wing: insects by hawking, birds are flown down: even swifts and swallows often cannot outpace or outmanoeuver a hobby.
