Scarlet-chested Sunbird
Chalcomitra senegalensis
A large dark sunbird with a long decurved bill. The male is spectacular, glossy velvet-black with a striking scarlet daub on the chest and an iridescent green crown and throat. The female is dark gray-brown and heavily streaked underneath. Singles and pairs occupy a broad variety of dry and moist savanna, parkland, and gardens, eating nectar and insects. The species gives a loud series of “tjip” and “teeeuw” notes. Hunter’s Sunbird differs from the similar Scarlet-chested Sunbird by having a violet rump and shoulder patches and having a black central throat (not iridescent green).
识别特征
The scarlet-chested sunbird is similar to Hunter's sunbird in appearance, with adult males having a characteristic red–scarlet coloured breast and an iridescent green patch on top of its head. The female is dark brown with no supercilium. It inhabits woodland and gardens, at elevations of up to 2,400 metres (7,900 ft). The bird is around 13–15 centimetres (5.1–5.9 in) in length, with males having a weight of 7.5–17.2 grams (0.26–0.61 oz) and females weighing 6.8–15.3 grams (0.24–0.54 oz).
分类信息
In 1760, the French zoologist Mathurin Jacques Brisson included a description of the scarlet-chested sunbird in his Ornithologie based on a specimen collected in Senegal. He used the French name Le grimpereau violet du Sénégal and the Latin Certhia Senegalensis Violacea. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition in 1766, he added 240 species that had been previously described by Brisson. One of these was the scarlet-chested sunbird. Linnaeus included a brief description, coined the binomial name Certhia senegalensis and cited Brisson's work. This species is now placed in the genus Chalcomitra that was introduced by the German naturalist Ludwig Reichenbach in 1853. Six subspecies are recognised.

Goliath Heron
Ardea goliath
This enormous heron stands 1.5 meters tall and has a robust, dagger-like bill. The immature has rustier upperwings than the adult. Its flight is ponderous and labored. Goliath Heron inhabits large rivers, marshes, estuaries, and mangroves, hunting for large fish and other animals, stabbing them with an open bill. It has a distinct, barking “kowoork” call that can be heard from up to 2 km away. Purple Heron has similar plumage, but Goliath Heron is twice the size, has a much larger bill, and has a rufous (not blackish) top of the head.
Little Bustard
Tetrax tetrax
A small brownish bustard with long legs and neck. May crouch if disturbed but when flushed, explodes noisily into a grouselike flight with whirring wings. Striking white wings with black tips are prominent in flight. Breeding-plumaged males are distinctive with black neck and double V-shaped white collar. Usually fairly quiet and unobtrusive. Found in open plains with shrubs and sufficient ground cover to hide in.
Robin Accentor
Prunella rubeculoides
A distinctive and common inhabitant of high-altitude open spaces such as pastures, steppelands, and mountain valleys. Bold and confiding, often visiting villages and towns where it forages for scraps with snowfinches, mountain-finches, and other accentors. Combination of ash-gray head, orange breast, and white belly is unique amongst the birds in its region.
