Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Falconiformes (Sharpe, 1874)


The order Falconiformes is a group of about 290 species of birds that include the diurnal birds of prey. Raptor classification is difficult and the order is treated in several ways.

Classification problems :
Traditionally, all the raptors are grouped into 4 families in this single order. However, in Europe, it has become common to split the order into two: the falcons and caracaras remain in the order Falconiformes (about 60 species in 4 groups), and the remaining 220-odd species (including the Accipitridae - eagles, hawks, and many others) are put in the separate order Accipitriformes. A prehistoric family known only from fossils are the Horusornithidae.

The idea that Falconiformes should be divided into many orders is because of the suggestion that the order may not share a single lineage that is exclusive of other birds. The most controversial but also most well-supported suggestion, is that Cathartidae are not Falconiformes but are related to the storks, in the separate order Ciconiiformes. However, morphological evidence supports the common ancestry of the Falconiformes, and the Strigiformes may be very close to the Falconiformes as well.

The American Ornithologists' Union reintegrated the New World vultures (family Cathartidae) into Falconiformes in 2007. This goes against the influential Sibley-Ahlquist taxonomy, in which all the raptors are placed into Ciconiiformes, but the Cathartids are considered to be outside the lineage that includes other raptors. While the latter is apparently correct, the "Ciconiiformes" sensu Sibley & Ahlquist are a paraphyletic, artificial assemblage and one of the weakest point of their classification scheme.

Karyotype analysis indicates that New World vultures are indeed distinct, and the Accipitridae stand apart from all other falconiform birds insofar as that their microchromosomes show a high degree of merging to medium-sized chromosomes, which is quite unique in birds (de Boer 1975, Amaral & Jorge 2003, Federico et al. 2005). Whether this has any bearing on the validity of the proposed Accipitriformes is still a matter of dispute, but it at least proves that the accipitrids are a monophyletic group.

Hallo Thijs,
Mooie in flight foto met aangename grijswaarden.
Persoonlijk zou ik de 'linten' editen door cloning bijvoorbeeld.
Goed gedaan

Hello Thijs -

Well done to capture this bird in flight in such low lighting conditions. Exposure and sharpness are spot on the money. Bravo, well done!

Thank you for sharing.


Amazing action shot :)
The falcon is completely sharp.
The blurred background gives an impression of the falcons tempo.

Well done

hello friend
a beautiful capture
a successfull snap of photgraphy at high shutter speed
the skills involved in taking this pic are highly appreciated
good work
the note is also very informative

Thijs, Well taken. You had been quick to capture the bird to the left in the frame leading to nice composition. The colors are very good. The details are excellent.

HI Thijs,
a fine inflight shot with a nice panning,very good sharpness and details.
Maybe the picture is a bit dark but thats a minor nit.
Well composed and good POV.
Well done.

Hello Thijs,
Beautiful image, clear detail and no fall-off in focus/DOF across the entire wingspan, great framing/crop and also superb colours/contrast. The bird stands out nicely against the dark BG with excellent detail in the feathers and eye. A great capture.

Hi Thijs,
Nice photo. It is an adult Geranoaetus. I can't dice out the race because I would need to see it ventrally. A buteonine. There is now a move on after genetic analyses to eliminate this generic name and place this bird in genus Buteo.

Forget the Sibley-Ahlquist sequence. Even among the SACC contributors there is now starting to be a convergence of opinion to adopt, at least in part, some of the sequence of the Howard & Moore. Everyone is waiting for 2009 when the HM 4° Ed. will be published.

By the way, any relation to the ornithologist/conservationist of clear fame, Bas van Balen?

Hallo Thijs,
Excellent shot
great sharpnes and details

Woooow, Thijs,
that's marvelous, I love that moment, action and power, fantastic work, thanks

Thijs, What a shot and what an eye catch. Can u please give me some tip on how to shoot such moving scenes. I tried but do not want to give up. Your shot is amazing and awesome friend. Ganesh

Great picture with good colors and fantastic sharpness made in the exactly right moment!

bonjour thijs
excellente capture en vol de ce rapace,il est net et detaillé,je me suis juste permis un WS pour un leger bruit residuel dans le BG.

Wow awsomwe shot the details are great excellent pov and very well composed tfs rgds Necip.

Hi Thijs,
Excellent panning capture with the BG motion blur effect..
Excellent exposure of this difficult subject also..Very nice sharpness, details, color, DOF, and composition :)
Great inflight work!

hello Thijs,
what a nice capture of this king. Action, moment, pose super. Sharpness/details, coloration superb. BG also nice. Composition and frame very nice. thanks. best wishes

Amazing picture.....Excellent shot.....
