18-4-2018 CHOBE NAT PARK, BOTSWANA - MARTIAL EAGLE (Polemaetus bellicosus)

The Martial Eagle (Polemaetus bellicosus), a formidable raptor, reigns over the sub-Saharan skies. This solitary species, the sole member of its genus, is distinguished by its impressive size and power. With feathered tarsi characteristic of the booted eagle subfamily, it is one of the largest of its kind. The Martial Eagle is an apex predator, soaring high to stoop upon a diverse array of prey, from mammals to reptiles.

Adult Martial Eagles exhibit a dark brown plumage on their upperparts, head, and upper chest, with occasional lighter feather edges. Their underparts are white, marked with sparse blackish-brown spots. In flight, their long broad wings and short tail give them a distinctive silhouette. Juveniles are paler with a greyish mottled appearance and take up to seven years to acquire their adult plumage.

The Martial Eagle favors wooded belts within open savanna landscapes, avoiding dense forests and arid deserts. It is often found perched in an upright position in large trees, surveying its territory.

This eagle's range spans across sub-Saharan Africa, with higher densities in southern and parts of east Africa. It is more sporadic in west Africa, with notable populations in protected areas such as South Africa's Kruger National Park.

Martial Eagles spend a significant portion of their day aloft, soaring at great heights. They are solitary outside of the breeding season and exhibit a preference for less disturbed areas, likely due to the abundance of prey and aversion to human activity.

The Martial Eagle is not a frequent vocalizer, but it does emit a low mellow whistle as a contact call and a louder, trilling call during territorial displays.

Breeding occurs at various times across their range, with nests built high in large trees. They lay usually one egg, with the female performing most of the incubation. Fledglings remain dependent on their parents for several months post-fledging.

The Black-chested Snake Eagle may be confused with the Martial Eagle but is significantly smaller with different coloring and flight patterns. Juvenile Martial Eagles may be mistaken for juvenile Crowned Eagles but differ in wing and tail proportions.

Martial Eagles are opportunistic predators, with a diet comprising mammals, birds, and reptiles. They are known for hunting from a high soar, using their keen eyesight to spot prey from several kilometers away.

The Martial Eagle is currently classified as Endangered by the IUCN, with populations declining due to factors such as persecution, habitat destruction, and collisions with power lines. Conservation efforts focus on education and the expansion of protected areas.

18-4-2018 CHOBE NAT PARK, BOTSWANA - LITTLE BEE-EATER (Merops pasillas)

The little bee-eater (Merops pusillus) is a bird species in the bee-eater family, Meropidae. They are found in Sub-Saharan Africa. They should not be confused with the little green bee-eater (Merops orientalis). Migration is limited to seasonal movements depending on rainfall patterns.

Members of this species, like other bee-eaters, are rich and brightly-coloured slender birds. They have green upper parts, yellow throats, black gorgets, and rich brown upper breasts fading to buffish ochre on the belly. Their wings are green and brown. Their beaks and legs are black. They reach a length of 15–17 cm, which makes them the smallest African bee-eater. Sexes are alike. Often silent, their call is a soft "seep".

These are abundant and tame birds, familiar throughout their range. There have been estimated to be between 60-80 million little bee-eaters. They breed in open country with bushes, preferably near water. Just as the name suggests, bee-eaters predominantly eat insects, especially bees, wasps and hornets, who are caught in the air by sorties from an open perch. This species often hunts from low perches, maybe only a metre or less high. Before eating their meal, a bee-eater removes the stinger by repeatedly hitting the insect on a hard surface.

The Coppery-tailed Coucal's range extends across south-central Africa, from Angola in the west to southwestern Tanzania, and includes northern Botswana and the Caprivi Strip in Namibia. Its territory spans an impressive 1,750,000 square kilometers.

17-4-2018 CHOBE NAT PARK, BOTSWANA - BLACKSMITH LAPWING (Vanellus armatus)

The Blacksmith Lapwing, known scientifically as Vanellus armatus, is a striking bird with a bold pattern of black, grey, and white, which may serve as a warning to predators. Its red eyes are a distinctive feature, shared with only four other lapwing species across the globe. Adorning the wrist joint is a carpal spur, a sharp black protrusion used in defense of their young, with aggressive aerial dives often aimed at the heads of intruders.

When identifying the Blacksmith Lapwing, look for its red eyes and the contrasting pied plumage. The bill and portions of the legs are black, with the legs sometimes showing a white-grey mottling. The sexes appear similar, though females tend to be slightly larger and heavier.

This lapwing species is commonly found in association with wetlands of varying sizes, from expansive marshes to the smallest damp areas caused by spilling water troughs. In South Africa, they are particularly abundant in mesic grassland regions.

The Blacksmith Lapwing is a common sight from Kenya through central Tanzania to southern and southwestern Africa. They have expanded their range in the 20th century, notably establishing a presence in the western Cape region of South Africa since the 1930s.

Partially migratory, the Blacksmith Lapwing does not engage in large-scale, regular migrations. They are known to be aggressive during the breeding season, particularly towards other lapwings or African jacanas entering their territory.

Breeding occurs in spring, with nests being shallow depressions on bare ground or short grass near water. The nests are typically spaced at least 400 meters apart. After breeding, the young gradually separate from their parents and do not return to their natal areas.

The diet of the Blacksmith Lapwing consists of aquatic and terrestrial invertebrates, which they forage for in their wetland habitats.

The IUCN Red List classifies the Blacksmith Lapwing as Least Concern, indicating that the species does not currently face a significant risk of extinction.

17-4-2018 CHOBE NATIONAL PARK, BOTSWANA - SABLE ANTELOPE (Hippotragus niger)

The Sable antelope (Hippotragus niger) is an antelope which inhabits wooded savanna in East and Southern Africa. Local names for this species include swartwitpens (Afrikaans), kgama or phalafala (Sotho), mBarapi or palahala (Swahili), kukurugu, kwalat or kwalata (Tswana), ngwarati (Shona), iliza (Xhosa), impalampala (Zulu) and umtshwayeli (Ndebele).

The Sable antelope has a compact and robust build, characterized by a thick neck and tough skin. It has a well-developed and often upright mane on its neck, as well as a short mane on the throat. Its general coloration is rich chestnut to black. Females and juveniles are chestnut to dark brown, while males begin darkening and turn black after three years. However, in southern populations, females have a brown to black coat. Calves less than two months old are a light tan and show faint markings. The underparts, cheek, and chin are all white, creating a great contrast with the dark back and flanks. Long, white hairs are present below the eyes, and a wide, black stripe runs over the nose. Both sexes have ringed horns that arch backward. In females, these can reach 61-102 cm (24-40 in), while in males they are 81-165 cm (32-65 in) long.

Sable antelope live in the southern savannas of Africa from the southeastern part of Kenya, in eastern Tanzania, as well as Mozambique to Angola and in southern Zaire, mostly in the Miombo Woodland Zone. They prefer a mixture of grassland and savanna woodlands and avoid vast open lands where possible.

Sable antelope are diurnal but are less active during the heat of the day. Most antelope will travel about a mile each day, even less when it is the dry season. They live in herds numbering 10 to 30 individuals, typically females with their young with one male leader. Just a few of the most dominant mature males can obtain and hold territories, which they try to set up in the best feeding areas, because the better the feeding prospects, the more females will be attracted to the area. These animals are timid like most other antelope but will become aggressive, particularly the males, which can become dangerous if attacked or approached. When Sable antelope are threatened by predators, including lions, they confront them, using their scimitar-shaped horns. Many of these big cats have died during such fights.

Sable antelope are herbivorous (folivorous, graminivorous) animals. They are specialized browsing animals and feed upon foliage, leaves, medium-length grass, and herbs, especially those growing on termite mounds. The leaves of trees provide 90% of their diet. They also visit salt licks and have been known to chew bones to collect minerals.

Sable antelope are polygynous. Dominant males defend groups of females and their foraging territory, which can extend 300 to 500 meters from the herd. The dominant males vigorously defend the females in their harem against intruding males. The breeding season extends from May to July. The gestation period is around 9 months and a single calf is born, which is then left hidden in the bush or tall grass. The mother returns once or twice each day to suckle her young. In a couple of weeks, the calf will be strong enough to join the herd. Weaning occurs 6 months after birth. Breeding for females starts at 2.5 years old and for males at 5 years old.

16-4-2018 CHOBE NATIONAL PARK, BOTSWANA - NOMINATE YELLOW BILLED OXPECKER (Buphagus africanus ssp africanus)

The Yellow-billed Oxpecker, Buphagus africanus, is a passerine bird, a member of the Buphagidae family. It is a bird of the savannah, easily recognized by its strong, direct flight and the distinctive yellow and red bill in adults, with juveniles sporting a brown bill.

Adult Yellow-billed Oxpeckers measure around 20 cm in length. They exhibit plain brown upperparts and head, with buff underparts and a pale rump. The bill is a notable feature, yellow at the base and red at the tip in adults. Their feet are robust, adapted to their unique lifestyle.

This species thrives in the savannah regions of Sub-Saharan Africa, where it can be found perching on large mammals.

The Yellow-billed Oxpecker is native to Sub-Saharan Africa, ranging from Senegal east to Sudan and down to northeast South Africa. It is less common in the eastern extremes of its range.

Outside of breeding season, Yellow-billed Oxpeckers are quite sociable, forming large, chattering flocks. They have a symbiotic relationship with large mammals, feeding on the parasites found on these animals. At night, non-breeding birds may roost on their host animals.

The call of the Yellow-billed Oxpecker is a hissy, crackling "krisss, krisss," which can be heard as they go about their activities.

Breeding Yellow-billed Oxpeckers nest in tree holes, which they line with hair plucked from livestock. They lay clutches of 2-3 eggs.

The Yellow-billed Oxpecker can be confused with the Red-billed Oxpecker, but the yellow base of the bill is a distinguishing feature.

Their diet consists primarily of insects and ticks, with a particular penchant for blood. They may consume over 100 engorged female ticks or thousands of larvae in a single day. They also feed on blood directly by pecking at wounds on their host mammals.

The IUCN Red List has classified the Yellow-billed Oxpecker as Least Concern, indicating a stable population.

15-4-2018 CHOBE NATIONAL PARK, BOTSWANA - LILAC BREASTED ROLLER (Coracias caudatus)

The lilac-breasted roller (Coracias caudatus) is a member of the roller family, Coraciidae, resplendent in a panoply of pastel hues. This African bird is a sight to behold, with its lilac throat and breast, olive crown to mantle, and cheeks of lilac-rufous. The species is further adorned with long, black tail streamers, which juveniles lack. Unofficially, it is considered the national bird of Kenya.

In the field, the lilac-breasted roller is almost unmistakable. Adults boast a lilac throat that deepens into a darker lilac breast, with an olive crown and mantle. The cheeks and ear coverts are a lilac-rufous. Juveniles and immatures can be identified by their lack of tail streamers and a throat and breast of rufous-tawny with broad diffuse buffy-white streaks. The species is not sexually dimorphic, though males may be slightly larger.

The lilac-breasted roller favors open woodland and savanna, typically avoiding treeless expanses. They are often seen perched high, surveying the landscape for prey.

This species is widely distributed across Southern and Eastern Africa and is a vagrant to the southern Arabian Peninsula. It is most abundant in Kenya and can be found from sea level to elevations of 2,000 meters or more.

Lilac-breasted rollers are usually solitary or found in pairs. They are known for their aggressive defense of their nests against raptors and other birds. During the breeding season, males perform acrobatic flights, swooping and diving while emitting harsh cries.

The call is a harsh, sawing "rak rak rak," typically delivered in flight. The bird often perches to vocalize.

The lilac-breasted roller is likely monogamous, nesting solitarily. Both sexes incubate the clutch of 2–4 eggs. The nest is located in a natural hole in a tree or termite mound, and the young are altricial, becoming fully feathered after 19 days.

Their diet consists of arthropods and small vertebrates, including insects, spiders, scorpions, and small birds. They hunt from perches, swooping down to catch prey on the ground or in the air.

The IUCN lists the lilac-breasted roller as Least Concern, with a stable population size and a large range.
