[Note Guidelines] Photographer's Note
This is my 900th posting on TN.
I’ve chosen for one of my favourite birds, which I’ve seen in Africa several times, the Bateleur, but could never made a decent photo of it. This photo is made in the biggest bird park on earth in Walsrode, Germany.

The Bateleur (Terathopius ecaudatus) is a medium-sized eagle in the family Accipitridae. Its closest relatives are the snake eagles. It is the only member of the genus Terathopius and may be the origin of the "Zimbabwe Bird", national emblem of Zimbabwe. It is endemic to Africa and small parts of Arabia. "Bateleur" is French for "Street Performer".

Description and Behavior
The average adult is 55 to 70 cm long with a 186 cm wingspan. The wing chord averages approximately 51 cm. Adult weight is typically 2 to 2.6 kg .
The Bateleur is a colourful species with a very short tail (ecaudatus is Latin for tailless) which, together with its white underwing coverts, makes it unmistakable in flight. The tail is so small the bird's legs protrude slightly beyond the tail during flight. The Bateleur is sexually dimorphic; both adults have black plumage, a chestnut mantle and tail, grey shoulders, tawny wing coverts, and red facial skin, bill and legs. The female additionally has tawny secondary wing feathers. Less commonly, the mantle may be white. Immature birds are brown with white dappling and have greenish facial skin. It takes them seven or eight years to reach full maturity.

The Bateleur is diurnal, and hunts over a territory of approximately 250 square miles (650 km2) a day. Bateleurs are hunters and scavengers; birds such as pigeons and sangrouse are preferred prey items, although it may attack small mammals and also takes carrion. The Bateleur is generally silent, but on occasions it produces a variety ofbarks and screams. The bird spends a considerable amount of time on the wing, particularly in low-altitude glides.

"Bateleur" is French for "Street Performer" which included performers such as tight-rope walkers. This name implies the bird’s characteristic habit of rocking its wings from side to side when gliding, as if catching its balance.

The Bateleur breeds in December–March. It constructs a well-concealed nest in trees, laying a single egg which is incubated by the female for 42 to 43 days, with a further 90 to 125 days until fledging. Bateleurs pair for life, and will use the same nest for a number of years. Unpaired birds, presumably from a previous clutch, will sometimes help at the nest.
Bateleur eagles are among a group of raptors that secrete a clear, salty fluid from their nares whilst eating. According to Schmidt-Nielson's (1964) hypothesis, this is due to the general necessity for birds to use an extrarenal mechanism of salt secretion to aid water reabsorption.

Distribution and Habitat
The Bateleur eagle is a common to fairly common resident of the open savanna country and woodland (thornveld) within Sub-Saharan Africa; it also occurs in south-west Arabia. Total distribution size is estimated at 28,000,000 km2. The bird's range has diminished significantly in recent decades, possibly due to poisoning.

Conservation
In 2009, the Bateleur was placed in the Near-Threatened IUCN Red List Category due to loss of habitat, pesticides, capture for international trade and nest disturbance. Decline of the species is suspected to have been moderately rapid over the past three generations. Current conservation efforts are unknown. Like the Martial Eagle, the Bateleur is reasonably common in conservation areas and scarce elsewhere.

Global population is estimated at 10,000 to 100,000 individuals.

Hello Peter
Congratulation for your 900th Photograph here in TN. It is a long journey and hope you will continue your work.
Beautiful species this Bateluer. Outstanding details and sharp photograph. Majestic pose with bright eye; like it.

But I think you will be agree that surrounding atmosphere doesn't mach here in Bird Park for this beautiful bird, which you can get in Sub-Saharan Africa. More over, it's more challenging to me to capture in natural habitat where birds are totally free. So personally I don't like Bird Park Picture and I don't go for it.
Thanks for sharing such attractive bird with informative NOTE,
Regards,
Srikumar

Hello Peter,

Hi Peter,nothing better to celebrate your 900th post,this curious bird is absolutely beautiful! What a elegant and serious pose and what a magnificent quality,i like it! Have a nice day and thanks,Luciano

Congratulations on your 900 posts. Thank you for persisting with TN when so many good photographers have gone to other internet platforms.
Very imposing subject, sharp against the dark background. Nice eye catch.
Although I understand Srikumar's issue with captive animals, I think sometimes this is the only way to show strange and rare living beings that most of us would never see in their natural habitats. As long as the note indicates that the photo was taken in a captive setting (including a garden or botanical garden), and the species are chosen for their rarity.

Hello Peter, and Congratulations on your attractive 900th post.
I'm sure with the kind of persistence you possess you will one day capture this awesome bird in it's natural habitat, but for now we can enjoy this gorgeous presentation. Exceptional detail and superb natural coloration. What a beautiful specimen and a new bird for me.

Hi Peter
Strange, interesting and beautiful bird.
Sharp details and well chosen dof.

A fabulous picture to feature as your 900th, Peter. Congratulations! It is the sheer quality of your pictures that counts even though 900 of them are quite an impressive sum.
The image of this good looking Eagle you shot in Germany is a professional job. The pose of the bird is elegant and the surroundings give a good impression of its natural habitat.
Looking forward to your 1000th post!
