|Kucuk Kerkenez- Lesser Kestrel- Falco naumanni |
Adult male lesser kestrel leaving a signature in the air :o)
*The Lesser Kestrel (Falco naumanni) is a small falcon. This species breeds from the Mediterranean across southern central Asia to China. It is a summer migrant, wintering in Africa and Pakistan. It is rare north of its breeding range, and declining in its European range.
It is a small bird of prey, 27-33 cm in length with a 63-72 cm wingspan. It looks very much like the larger Common Kestrel but has proportionally shorter wings and tail. It shares a brown back and barred grey underparts with the larger species. The male has a grey head and tail like male Common Kestrels, but lacks the dark spotting on the back, the black malar stripe, and has grey patches in the wings.
Despite its outward similarity, this species appears not to be closely related to the Common Kestrel. In fact, mtDNA cytochrome b sequence analysis (Groombridge et al. 2002) places it at a basal position with regards to the other "true" kestrels (i.e., excluding the American Kestrel and probably the grey African kestrels too). Its divergence is tentatively placed to around the Miocene-Pliocene boundary (Messinian to Zanclean, or about 7-3.5 mya). The morphological similarity with the Common Kestrel is most puzzling, but still it appears to betray the present species' actual relationships: the lack of a malar stripe seems ancestral for kestrels, and the grey wing color unites the Lesser Kestrel with most other Falco species, but not the other true kestrels.
The Lesser Kestrel is, as the name implies, a smaller and more delicate bird than the Common Kestrel, and it is entirely sympatric in its breeding range with it; they compete to a limited extent. Thus, the possibility that there is some form of adaptive advantage to the similar coloration deserves study. Considering that the Lesser Kestrel would in fact have an advantage if some would-be predators confuse it with the larger species and consequently avoid it, it might be a case of Müllerian mimicry.
The Lesser Kestrel eats insects, which are often taken on the ground. It nests colonially on buildings, cliffs, or in tree holes, laying up to 3-6 eggs. No nest structure is built, which is typical for falcons.
It is widespread and plentiful on a global scale, but in many areas of its range, it seems to be undergoing a marked and possibly accelerating decline. The IUCN has thus classed it as a vulnerable species (VU A2bce+3bce). This means that the global population and range have declined by some 30% in the last 10 years, and is expected to continue to do so for at least another decade. Apart from possible habitat destruction, it appears that indiscriminate use of pesticides has a strong effect on this species due to its insectivorous habits (BirdLife International 2006).

Bon réflexe, belle position des pattes.
Really cool shot, Selen!
I hope he didnt sign on you :)
Wow... this is a super shot. The clarity is fantastic. Nice colours and great POV showing the underside of this beautiful bird. Congrats! :-)

Another great one, Selen. Excellent sharpness and contrast make these kestrel shots some of the best on TN. Well done.

Tam anında! Şahane bir kare!
A wonderful super sharp image with a toch of fun to it. The frozen action of its signature is wonderful, and it seems you got eye contact with the bird. The clear blue sky really helps to isolate the two subjects.
Zor bir fotograf kuşun netliği ve arka alt taraftaki detay mükemmel görüntülenmiş Tebrik ederim Selen.
Hi Selen , Excellent capture , very sharp flight photo , strangely there's contrast difference line of the blue sky at the upper right of the frame , good luck.
