Four-banded Sandgrouse
Pterocles quadricinctus
A small, short-tailed, intricately marked sandgrouse. The distinctive male has black marks on top of the head and three bands across the underparts. The female is plainer. Both sexes have a finely barred dark belly. Found in savanna and cultivation. Usually in pairs or small groups. Similar in size and shape to Lichtenstein’s Sandgrouse, but lacks that species’ fine barring on the underparts. Female separated from female Black-faced Sandgrouse by the lack of a strong white mark across the underparts. The call is a rattling, high-pitched “brrr-eeee,” often given in flight.
识别特征
The four-banded sandgrouse is 25–28 cm long. Its head, neck and upperparts are yellowish-green, with the back heavily marked with brown. The male has black and white bands on its forehead as well as black and white bands separating the breast from the heavily barred belly. The female lacks the head and breast bands and is heavily barred on the back and flanks. It has a small, pigeon-like head and neck, but a sturdy compact body. It has long pointed wings, which are grey underneath, a short tail and a fast direct flight.

分布与栖息地
This gregarious species occurs in a belt across Africa from Mauritania and Cameroon east to Sudan and Uganda. It is much more common in the west of its range. It is a partial seasonal migrant, with some birds moving further north in the rainy season. It breeds on open areas with some trees, including savanna, scrubland and similar habitats.

行为
Flocks fly to watering holes in the evening to drink and are largely nocturnal. The call is a loud wulli-wulli, and there is much twittering at the drinking holes. The nest is a ground scrape into which 2 or 3 buff eggs with brown markings are laid. Both sexes incubate.

其他鸟类
White-bellied Tody-Tyrant
Hemitriccus griseipectus
Tiny short-tailed flycatcher of lowland rainforest midstory. Olive-gray above, white below; grayer above and paler underneath than similar small canopy species like Dwarf Tyrant-Manakin and greenlets. Calls constantly throughout the day but still hard to see as it perches motionless on a branch until buzzing to a new perch. Listen for its distinctive short hiccuping call: “ta-teek”.
Rusty-necked Piculet
Picumnus fuscus
Uncommon piculet of riverine and flooded forests, found only in a very limited area along the Brazilian/Bolivian border. Usually seen alone or in pairs below the forest canopy. Plumage generally brownish, but note the black top of the head. Male and female are very similar, except for the orange-reddish feathers in the male’s crown. Voice consists of 5–7 short, sharp whistles, dropping at the end: “tzi-tzi-tzí-tzí-tzíu.”
Royal Tern
Thalasseus maximus
Large tern, found strictly in coastal areas. Feeds in open ocean and saltwater bays, where it flies high above the water looking for small fish. Rests on beaches, often in groups with other species. Separated from many terns by large size; only slightly smaller than Caspian. Look for the thinner orange bill (usually not deep red) and shaggier crest compared with Caspian. Also, forehead whiter than Caspian Tern in the nonbreeding season; this can show as early as midsummer.
