Hello,

The African Darter is a monogamous bird which means that the bird finds and breeds with one partner for the rest of its life. The bird lays between 2 to 6 eggs and they are coloured white.

The bird builds its nest on the ground with figs, straw and leaves. The nest is placed under a bush to protect the young from predators.

The African Darter is found in the Southern African wetlands, riverine forests and moist grasslands.

The bird is at home in riverine forests and close to water bodies such as lakes, dams and streams,

This is an adult African darter, Anhinga rufa. Some authorities place this bird into the family, Anhingidae, whilst others classify them into the same family with cormorants (shags), Phalacrocoracidae. It is thought that darters and cormorants are sister taxa because they have very similar morphologies and behaviours, but these taxa can be readily distinguished by their beak shape: all darters have a long, slender, sharply pointed beak with serrated edges.

In total, there are four species of Anhingas, all closely related: the Anhinga or American darter, A. anhinga, the Australian or Australasian darter, A. novaehollandiae and the Oriental or Indian darter, A. melanogaster. The three Old World darters are sometimes lumped together as subspecies within A. melanogaster.

Some of you were mislead by this bird's kinked neck, which is the result of convergent evolution -- a situation where function defines form. Both darters and herons have an s-shaped kink in their necks that facilitates their ability to catch prey. That kink allows the bird to snap its head forward with lightning speed so they can stab fish with that sharp beak. This s-shape is supported by morphological specialisations to the structure of the vertebrae and musculature of the neck. It also gives these species the ability to confuse bird watchers because they fly with their necks kinked,
Regards,

Pauly.

Ciao Paul, great capture of lovely cormorant in fantastic pose, excellent sharpness, fine details, splendid light and colors, very well done, my friend, ciao Silvio

Hi Paul,
A Great capture of the African Darter! Believe my or not but I have had the experience of seeing the stabbing in real life! My previous sport was angling and when sitting on the boat for 10 hours on Loskop dam during a competition you can not ignore the Fishing Eagle catching it's prey, the African Darter on a dry branch stabbing it's prey and many more. The details on your exposure is significant to what I have seen. Beautiful composition my friend. Well done with your exposure and notes!!
Best regards,
Carl

Hello Pauly,
I at first thought this was a Cormorant from the thumbnail image and was surprised to see it it actually a Darter. It looks very similar to the cormorant, but after reading your notes, I now see there is some distinct differances.
Love the pose and super fine detail you managed to capture. Color is true and natural and exposure is perfect. Great job on the photo and your very informative notes!!
Ron

Ciao Paul. Amazing playing of light on the bird in pose. Excellent details and sharp. Beuatiful colours.
