Southern Ground Hornbill / Bucorvus leadbeateri

The Southern Ground Hornbill is number 49 in the series of the birds of the Kruger National Park which I am still sharing. Enjoy!

If one directly translate the Afrikaans name of this bird 'Bromvoël' into English it will be 'Moan bird', and listening to the call this bird makes it sound a lot as if it is moaning, especially the juveniles. The young ones will walk and moan and groan non stop, wherever it goes. The adult birds are very photogenic and one always tries to get good photos of their lengthy whimpers. This female was captured from a group of 5 birds walking in the road on the way to the Transport Dam. The midday sun caused some lovely luminous reflections on its black feathers.


Biometrics
It is a large bird, at 90-129cm long. Females weigh 2.2-4.6kg while the males weigh 3.5-6.2kg.

Identification
It is characterized by black coloration and vivid red patches of bare skin on the face and throat (dull coloured in juvenile birds). The white tips of the wings (primary feathers) seen in flight are another diagnostic characteristic. The beak is black and straight and presents a casque, more developed in males. Female Southern Ground Hornbills are smaller and have violet-blue skin on their throats.

Voice
The call is an "oomph-oomph" frequently repeated.

Food
Mainly eats animals, such as insects, frogs, mongooses and bird nestlings. It forages in groups, so that when one bird locates a prey item it can signal the rest of the flock with a low bark. It often finds prey by digging, especially in dung heaps, and it may snatch food from birds of prey. Some of the food items that have been recorded in its diet are: snakes, lizards, chameleons, tortoises, mongooses, squirrels, young hares, birds and frogs. It rarely eats plants.

Distribution and Habitat
The Southern Ground Hornbill occurs from Kenya and the DRC to southern Africa, where it is widespread. It is fairly scarce in Botswana, Zimbabwe, Mozambique, KwaZulu-Natal (although we've been privileged to see some in the iMfolozi Game Park on quite a number of occasions), Eastern Cape, Limpopo Province and northern Namibia. It generally prefers grassland and savannah woodland habitats, ranging from montane grassland to extensive, tall stands of Zambezi teak, Mopane and woodlands with sparse under storey.

Breeding
Monogamous, cooperative breeder, with a group consisting of a dominant breeding pair and up to 9 helpers, who are either adult males or juveniles from previous breeding seasons. The group roosts in trees on rock faces, descending to the ground just before dawn and foraging for a lot of the day. They often take a break at midday to play, preen and pass around food to one another.

The nest is usually a cavity in a tree lined with dry leaves, rarely nesting in cavities in rock faces or earthen banks. The same site is used repeatedly over many breeding seasons. Egg-laying season begins with the first heavy summer rains, from August-January, peaking from October-November.

It lays 1-2, rarely 3 eggs 3-14 days apart, which are incubated solely by the female for 37-43 days. The female only makes 3-4 brief sorties out of the nest per day, so is largely reliant on the male and helpers to provide food. The eggs hatch in the sequence laid, meaning that the one chick is 3-14 days older than the other chick. The younger chick is unable to compete for food with its older sibling and dies of starvation when it is about one week old, occasionally surviving for a few more weeks.

The female leaves the nest when the chick is about four weeks old, after which the chick is mostly alone in the nest. The fledging leaves the nest when it is approximately 86 days old, remaining with its parents for several years.

Threats
Vulnerable in South Africa, were it has an estimated population of just 1500-2000. Its South African distribution range has decreased hugely recently, due to persecution and habitat alteration. Its range is also decreasing in areas of Swaziland, Zimbabwe, Botswana and other areas of high human population density or extensive farming. However it is still widespread in areas less populated by humans, such as north-eastern Botswana and northern Zimbabwe, but it is still never common. It is generally revered by African people, but it is also feared, leading to rare cases of it being collected for "muti" for bringing rain. Current conservation measures include hand-rearing of the otherwise redundant second born chicks, captive breeding and reintroduction.

Wondrous plumage, and perfect color registration (though difficult), with good texture and volume. It is an eloquent picture that allows the bird to see well!
Aldo a great note!

It is a beautiful picture of this huge Hornbill taken at mid-day, as its shadow on the ground suggests, Anna. The exposure is well balanced.
Thanks for sharing this gem from your nature rich country.

Ciao Anna. Excellent light and brilliant colours with perfect details/sharp and DOF. Another great shot from you!

Roberto

Hello Anna,
interesting bird indeed... a bird with a character,... not necessarily beautiful ;)but never the less a bird with strange massive bill and strikingly red throat. Great addition to your collection ....and TN of coarse! In my workshop here I am presenting you an alternative which addressing some issues in regards to the depth of field and the blueish color tint visible on the Hornbill plumage. Well I know f/5.6 with a compact/bridge camera will be equal to f/11 -13 almost on a APS-C sensor DSLR's and I doubt that you could improve dramatically the situation even at f/4 if you could set this number as an aperture, so this workshop here represent almost an impossible idea of blurring the background with the current hardware. The use of the shadow/highlights resolved some issues in regards to the high contrast scene, I think! Hope you like it Anna! Have a great day!

George Veltchev

Hello Anna,
That you could come so close! I've only seen a tamed one so close in Zimbabwe. The others were always shy. You were very lucky.
This is a very beautiful photo in a lovely natural setting. Excellent sharpness and taken from a very good POV. I'm very curious for nr. 50. Something special I hope.
Regards,
Peter

Hello Anna,
You are right, these birds are very photogenic despite the black plumage. But with their impressive shape and the red parts as contrast they cannot escape to our eye. What I like also on this shot is the majestic way to walk of your specimen. Lovely natural picture. Very well done!
kind regards
Anne

Another Impressive bird of Africa Anna! Beautiful photo with good composition, wonderful colours and impressive sharpness.

Christodoulos

Hello Anna,
Yes, I agree with Peter...No 50 will be a milestone and I am looking forward to it very much. your series "Birds of Kruger National Park" MUST please be published. This is a fabulous image of a Ground Hornbill...I know how difficult it is to get close to it...this one, I think, does not sit, or strut, around in bird sanctuaries. So no armchair photography I think? Very well done indeed.

Hi Anna, fabulous capture of this remarkable Bird, splendid exposure/white balance control with terrific saturated colours, nice and sharp, superb composition here Anna and very well done,
Best regards,

Pauly.

Anna, great shot of this hornbill. Has great sharpness, detail and POV. Have a wonderful day, Bill

Hi Anna,
the hoornraaf: certainly not a to be called a beauty, but an unforgettable truly majestical appearance! Very well presented from a strictly rectangular approach that gives a description just as perfect as an excellent painted illustration. Inspite of the hard sunlight of noon even the dark parts in the shadows of feathers are well visible, indeed there is an impressively rich spectre of shades and details made visibe by you. Thank you! Enjoy the new Springtime arriving! With best regards from Vienna where the last hot days of summer are just ending in some locally heavy thurnderstorms by the arrival of Autumn,
Peter

Hello Anna,
The bright red eye patch and wattle makes this guy stand out like a sore thumb. It has very stout looking legs, which I'm sure come in handy for digging for insects. The bill also looks to be of the heavy duty type, and judging from it's vast assortment of diet, probably comes in handy.
The sun was favorable to you on this particular day, as the dark feathers show some signs of colorful iridescent colors. Wonderful detail is shown and the exposure is right on the money!! Well done!!
Ron
PS. Rosie and I are having a blast, as we have all six grandchildren home at this time. We will have one more week of this, then two go back home to Oklahoma.

Hi Anna
Nice record shot of this hornbill. Nice and sharp with good feather detail
