Bateleur Eagle (Terathopius ecaudatus)

Lacking a long tail, the bateleur rocks side to side in flight, a mechanism for steering. Other birds just pivot their tails. This action reminds viewers of a tight wire act with the long pole used for balance, hence its name. Bateleur means "balancer." I am not sure what Terathopius means, but ecaudatus means "without a tail," and the bateleur looks like it does not have a tail - its tail is very short.

The Bateleur eagle is the most famous of the snake eagles. Its pitch black feathers with white under the wings, bright red face and legs and black beak are characteristic markings. Unlike most creatures, female Bateleur eagles are larger than males. Bateleur eagles spend 8-9 hours each day in the air looking for food. Their diet includes antelope, mice, birds, snakes, and carrion.

The Bateleur eagle is found throughout Africa south of the Sahara. It prefers tree and brush savannah.

Bateleur eagles pair for life and stay in the same nest for several years. Unpaired adults can sometimes be seen near a nest site. This bird is not rejected by the mating pair and does not help with nesting. The nuptial aerial display is spectacular, with steep dives by the male at the female. She will roll on her back, presenting her claws and then roll on over to right herself as he hurtles past. There may be follow-the-leader dipping and rolling flight, and there may be 360 degree lateral "barrel" rolls, which is often accompanied by a very loud slapping of the wings together. This percussion can be heard by humans for some great distance. All of this may be accompanied by very loud crowing calls.

A female will lay single egg in a nest that sits in a large tree that offers protection. Mother incubates the egg while father collects food and sticks for the nest. Sometimes, however, the father incubates. After an incubation period of 52-59 days, the baby Bateleur eagle hatches. 110 days later, the hatchling will leave the nest, but will continue to receive food from its parents for another 100 days. Only 2% of chicks make it to adulthood.

I am still finding it difficult to get great macro shots with my new camera and are posting a couple of nice bird mugshots that I seem to have under control. I hope you like them.

Excellent portrait, very nice work. I can't say much more about this as it is quite simply a great shot.

le noir sur le rouge ressort a merveille, le regard vif et le bec acer� de cette aigle font de ta photo un magnifique portrait ;)
merci bien .

Very classy portrait, Gerhard. Just what is needed to show how bright and sharp is an eagle eye. Perfect color match, on the low tones. Feathers might just need a bit more sharpness to enhance their texture. Anyway, a great portrait, and, as usual, a great note!

Great close-up, Gerhardt! I wish the focus a bit sharper and I am not sure that post process sharpening will enhance it as sometimes I find it makes jpeg artifacts and can ruin the image. So I would rather live with it like this if it were my image. Certainly a good image...color is wonderful as is the exposure.
