Post number 18 Birds from Southern Africa

These are photos again taken by my friend, Christelle Miller, while in the Kruger national park in May 2018.
Thanks go to Christelle for allowing me to use these photos on my blog.

I think next week I will take a break from South Africa, although I still have a number of Christelle's photos still to go through. I will turn to Europe for a couple of weeks with my own photos.

As always, I hope that my identification is correct, please let me know if there should be any mistakes.

Egyptian geese (Alopochen aegyptiaca).

African fish eagle (Haliaeetus vocifer), it feeds extensively on fish, in some areas it preys on flamingoes and other water birds. They live in pairs close to the streams. The nest is huge and made with sticks. The female lays two white eggs. Incubation lasts about 42 to 45 days, shared by both parents. Chicks remain at the nest for about 65 days. They can fly at about 70 to 75 days of age but are reliant on their parents for another 2 months. If you have never heard the call of the fish eagle, one of the best sounds in Africa, click here.

Great egret (Ardea alba), One of the most widely distributed birds in the temperate and warm tropical belts of the world. The staple diet is fish.  They live in colonies near salt and freshwater bodies, swamps, streams, and ponds. They build large nests of sticks, twigs, and leaves high up in trees. Female egrets usually lay pale bluish-green eggs, and incubation takes 3-4 weeks. Hatchlings are covered in soft white downy feathers. Both parents take turns to incubate the eggs and protect and look after the newborns.

Natal spurfowl or Natal francolin (Pternistis natalensis). It can be seen alone or in groups of around ten. This is a ground foraging bird. It forages at dawn or late in the evening. The diet of the Natal Francolin consists of mostly insects, roots, bulbs, molluscs, fruit and seeds. Their nests are just a small shallow scrape in the ground that is lined with grass. They use thick cover to keep their nests concealed. The female can lay up to seven eggs. The eggs are a cream colour and they take about 21 days to hatch. They breed all throughout the year.

Red-billed buffalo weaver (Bubalornis niger).  They are found in dry savannas and sparse woodlands They forage on the ground, taking various arthropods, but also various seeds and fruits. These birds breed in colonies and the males may be polygamous, each controlling 1-8 nest chambers and up to about 3 females. The nest is a huge, bulky mass of interconnected thorny twigs, divided into separate complexes with multiple egg chambers, each with a nest built by a female, consisting of a ball of grass, leaves and roots. Each female lays 2-4 eggs, which she incubates alone for about 14 days. The chicks are mostly fed by the female alone and fledge 20-23 days after hatching.

I think this is an African barred owlet (Glaucidium capense) It is a small owl, partly diurnal. Calling occurs mainly at dusk and dawn. Often observed on open perches scanning for prey even during the day. Roosts within cover, often in a natural cavity in a tree.  It feeds on small mammals, birds, reptiles, frogs, insects, scorpions and caterpillars which are normally caught following a short flight from a perch. Both sexes sing to proclaim their territory, most frequently before breeding. The nest site is usually a tree cavity between 10 to 20 foot from the ground. 2–3 eggs are laid from September to November. The young are fed by both parents but only in the dark, fledgling after 30–33 days and they become independent after 7–12 months.

Cape glossy starling (Lamprotornis nitens). Sexes are alike but the male is a bit larger. It eats insects, fruit, nectar and scraps of human food, doing most of its foraging on the ground. It is a monogamous, cooperative breeder, meaning that the breeding pair may be assisted by up to 6 helpers, who often remain with them through many breeding seasons. It usually nests in tree cavities, but it may also use a hole in a riverbank, metal pipe or even a post box. It adds coarse material such as twigs into the cavity after which it adds a lining of dry grass or dung. It often uses the same nest over multiple breeding seasons. It lays 2-6 eggs, which are incubated solely by the female. The chicks are fed by both parents and helpers, leaving the nest after about 20 days after which they remain with the group for at least week.

Southern white-crowned shrike (Eurocephalus anguitimens). male and female are alike, generally seen in flocks. It feeds on the ground and in foliage, mainly invertebrates. It is monogamous unless its mate dies and creates a nest in branches of a tree or shrub. The bird lays eggs which are white in colour and number between 2 to 5.

The Grey Heron (Ardea cinera). This is a particularly tall bird, standing at about a metre in height, males and females are similar. They are wading birds that favour areas like marshes, dams, lakes, lagoons, rivers and reservoirs. It is happy to eat whatever fish, crustaceans and other animals it can find in the water in which it wades.  It is a monogamous bird that will likely stick to an established heron nesting area, set up by previous generations in their natural habitat. These are called heronries. This bird will breed in a colony or as an individual, using flat nests in the tops of the trees.  These nests are constructed using sticks and twigs, and are then lined with grass and fresh leafy branches. The male presents the female with these building materials in a rather ritualistic way before she proceeds to construct the actual nest.  The female usually lays between three and six eggs during autumn or in the early part of winter. The male and female take turns to incubate these eggs for almost four weeks before they hatch. The tiny chicks are fed fish by means of regurgitation. They will take between 20 and 30 days to fledge.

The marabou stork (Leptoptilos crumenifer).  Their name comes from the French word “marabout”, which means 'ugly. It is sometimes called the "undertaker bird" due to its shape from behind: cloak-like wings and back, skinny white legs, They stand an average of 1.52m (5ft) tall. An average weight for this species is 9kg (20lbs). Their maximum wingspan is 3.19m (10.5ft) across. Their bill measures 26-35cm (10-13.8in). Male marabou storks are larger than the females. This species is a carnivore. Most of their food comes from scavenging by flying high above the ground. They will feed upon most varieties of live and dead prey including lizards, frogs, insects, rats, mice, birds, fish, crocodile eggs, young crocodiles and snakes. Marabou storks make their home on open savannahs near swamps, river margins and lake shores. They may even locate near fishing villages where they can steal scraps. Birds will congregate in groups ranging from 20 pairs to several thousand. Males first come and establish a territory. Then he greets newcomers with an inflated throat pouch. Soon he will accept a courting female into his territory. The pair then start to build their nest. This is constructed of sticks on a cliff side, in a tree, or on top of buildings in villages. Into this nest, two to three eggs will be deposited with a two to three-day interval between each. After 29-31 days they chicks will hatch.  It takes 13-15 weeks for them to be ready to fledge. Only one of the three chicks will make it to this stage. Four years after birth the chicks will achieve sexual maturity.

Three-banded plover, or three-banded sandplover (Charadrius tricollaris). It hunts by sight for insects, worms and other invertebrates. The nest is a simple scrape in sand, mud or shingle and the female usually lays one or two eggs. The most interesting part of the breeding cycle is the nest scraping ceremony. The male pushes his chest into the ground and then rotates his body to make a nest scrape while his back legs move backwards kicking up the sand. The male then moves away from the nest scrape, tail raised and neatens up the scrape by picking up and discarding fragments. The female then moves in for an inspection, also picking at fragments before moving away. The male will make several scrapes before the female is happy and chooses one! Once an egg has been laid it is incubated for 26-28 days before a perfect little chick hatches. Both adults care for the chick for up to 42 days. It will begin to fly at around 21 days.

Red-winged starling (Onychognathus morio). The adult male has glossy black plumage with dark blue sheen overall, except on the wings where the primary flight feathers are bright chestnut with narrow blackish tips. The female is very similar in plumage, but she has a brownish-grey head, chin, throat and upper breast. This bird frequents the mountainous areas with rocky outcrops and gorges, with access to vegetated feeding grounds although often now seen in urban areas. It feeds on numerous fruits, berries, seeds and nectar. It also consumes animal food such as amphibians and various insects Unlike numerous starlings, the Red-winged Starling builds its nest on a ledge, on a rock or cliff, but now also on buildings, and sometimes on leaf bases of palms. The nest-site is often reused for several successive years.  The nest is made with mud, grass, rootlets and sticks, and lined with finer grass, horsehair and also non-natural materials. The female lays 2-4 eggs and incubates over about two weeks. The male feeds her at the nest during this period. The chicks are fed by both parents, and they fledge about 22-28 days after hatching.

Post number 17 Birds from Southern Africa

These are photos again taken by my friend, Christelle Miller, while in the Kruger national park in May 2018.
Thanks go to Christelle for allowing me to use these photos on my blog.


I hope that my identification is correct, please let me know if there should be any mistakes.

Fork-tailed Drongo (Dicrurus adsimilis). They still-hunt by sitting very upright on a prominent perch, much like a shrike. They are usually solitary and form monogamous breeding pairs. They are aggressive and fearless, regularly mobbing or attacking much larger species, including birds of prey if their nest or young are threatened, or their territory is compromised. Two to four eggs are laid in a cup nest in a fork high in a tree.


Green-backed Heron (Butorides striata).  This bird has a specially adapted bill which helps it hunt for fish, crabs, shrimp and other aquatic animals in the water.  It also eats insects such as butterflies, bees, wasps, locusts and ants. It 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 blue, green. The bird builds its nest above water as a means of protecting itself from predators and to be close to its main food source which includes fish, shrimp and frogs.


Natal Spurfowl (Pternistis natalensis). The Natal Spurfowl feeds on the ground and in foliage, mainly on Invertebrates, Fruits or Seeds. It is monogamous unless its mate dies. They create a nest on the ground laying between 2 to 7 eggs. The preferred habitats for Natal Spurfowl are woodlands, river areas and hilly regions.

Red-crested korhaan (Lophotis ruficrista). It is omnivorous, feeding on invertebrates, especially termites, beetles and grasshoppers, and plant matter, especially seeds and fruit, foraging on the ground, picking up food items with its bill. The male puts on a spectacular courtship display to multiple females, who solely incubate the eggs and raise the chicks. See also Part 10.


African White-backed Vulture (Gyps africanus). They may be the most numerous of African vultures. It has gregarious feeding habits. It feeds mainly on carrion. It can be found in big numbers when food resources are abundant. These birds are adapted to feed on soft tissues, and cannot rip open large carcasses with thick skin.  It makes its nest in trees, and breeds in loose colonies. The nest is small in size, for these large vultures. It is located at the top of a tall tree in their territory and often along streams. It is a platform made of sticks, and the interior is lined with grass and green leaves. The female lays one single egg. Incubation lasts about 56 days, by both parents. Chicks are fed by both adults and may fledge at about 4 months.


African hawk-eagle (Aquila spilogaster). Both adults are similar in plumage, but the female is larger than male, and she is more heavily streaked on underparts than male.  They live in open woodlands and scrubs, where it can find rocky cliffs and wooded streams. is a secretive bird of prey, often seen alone, but also sometimes in pairs......  


 It searches for prey while flying, but also from a perch. It may catch prey taking it from the ground, or performing a dashing aerial manoeuvre.  The nest is located in a fork, in a tall tree, along wooded river banks. It is made of sticks.  The female lays one or two eggs. Incubation lasts about 43 to 44 days, shared by both parents. Only the strongest chick is reared if there is more of one egg.

Giant eagle-owl (Bubo lacteus). Africa’s largest eagle-owl, The female is substantially larger than the male and has a rounder facial disk.  It occupies a number of different habitats, including dry savanna, open woodland, open grassland, agricultural land and riparian habitat such as rivers, marshes and floodplains, but is largely absent from bare desert and dense woodland. Large trees are required for nesting, and nests are usually found in open woodland, adjacent to floodplains Due to the large size of the Eagle Owl, they need to consume larger types of prey than other species of owls. Their diet consists of rabbits, mongoose, and plenty of types of small game. They also consume rats and pigeons if they are readily available in their area of residence. These owls have a very long breeding season. It lasts from March until September. The females will usually have two eggs, but sometimes only one. They will incubate them for about 28 days. She will remain with the eggs from the time they leave her body until they hatch. It is the job of her mate to bring her back enough food for survival.   The first egg to hatch is the one that is the most likely to survive. The parents will feed this one immediately and continually. If they have enough food available they will feed both of the young. However, if food sources are scarce the second one will get no food at all. Sadly, it will die within a day or two. The young can fly when they are about 9 weeks of age.

Southern Ground Hornbill (Bucorvus leadbeateri) See also in Part 4. This particular hornbill species’ diet consists mainly of invertebrates that are readily found on the ground (including spiders), as well as lizards, snakes and amphibians.   It mates between September and December. The female will make her nest in a tree or a cliff hollow and will usually lay two eggs. Interestingly, she will lay the first egg about four days before the second, giving this chick the opportunity to be stronger than the other. Only one chick will survive to fledgling stage.  They are on the endangered list.

Lappet-faced Vulture (Torgos tracheliotos). The lappet-faced vulture is one of the most aggressive of African birds. It possesses one of the strongest beaks, usually arriving last to the carcass due to its ability to tear off flesh (such as skin, tendons, and other coarse tissue) that is too tough for smaller scavengers. They have a wingspan of almost 3 metres....

It frequents steppes and deserts with isolated trees such as flat-topped acacias where it may build the nest.   It needs open and arid areas, including mountains and semi-desert.  It usually lives in a pair, but flocks of up to 50 vultures can be seen mixed with other raptors around carcasses or at water. It dominates all other birds of prey around the food, performing some displays such as bounding attacks, but it spends more time in these displays than feeding, and it returns later to the carcass.  Pairs nest solitary, and build a large, bulky, flat nest (about 2 metres of diameter), with small sticks on a thorny tree-top. The interior is lined with dry grasses. The female lays only one egg in the middle of the nest. The young fledge at 125-135 days after hatching.  They do not breed until they are about 6 years of age and they are on the endangered list.

Post number 16 Birds from Southern Africa

I have been away for the past week so just a short post to let you know that I am back.  We are very busy with a number of jobs that are doing here at home at the moment. These are photos again taken by my friend, Christelle Miller, while in the Kruger national park in May 2018.
Thanks go to Christelle for allowing me to use these photos on my blog.

I hope that my identification is correct, please let me know if there should be any mistakes.

The Lilac Breasted Roller, (Coracias Caudata).  See my photos for details on this bird on the previous post.

African jacana (Actophilornis africanus) is a wader in the family Jacanidae, identifiable by long toes and long claws that enable them to walk on floating vegetation in shallow lakes,  which is their preferred habitat....

It feeds on aquatic insects and larvae, worms, snails and other arthropods. It may take seeds sometimes when it forages on open cultivated areas. To avoid predators, it can swim underwater, and in the same situation, the chicks can stay underwater for a moment with only the bill tip above the surface, and they swim as well as the adults. The mating system of the African Jacana is reversed. The male performs all the nesting duties while the female has access to several males and defends the territories against other females.

Brown Snake Eagle (Circaetus cinereu). It lives in savannahs, woodlands and dry wooded countries with tall trees. It is uncommon in open plains. It feeds on snakes and other reptiles, carrying them by the head while flying. It spends most of its time perched in trees, performing short flights from one tree to another, and hunting from these perches. Prey is always taken on the ground, often by dropping on it from a perch....

The nest is made with small sticks and lined with some green leaves. Birds may return to the same tree and rebuild a nest after some years.  The female lays only one white egg. Incubation lasts about 47 to 50 days, by the female. She flattens in the nest if an intruder approaches, becoming almost invisible. The male feeds her at the nest.
