Senegal Batis
Batis senegalensis
Typical black, white, and dark-gray batis. Note the chest band, which is black in males and rufous in females. The cap is dark gray, and there is a long eyebrow that is white in males and buff in females. Found in all types of savanna, ranging from moist Guinea savanna to dry thorn savanna. Often in pairs. Male very similar to male Gray-headed and Western Black-headed Batises, but has a broader eyebrow stripe, and is usually associated with the distinctive female. The song is more variable, quieter, and less distinctive than that of most batises; usually includes a combination of buzzing notes and higher whistled “kreit” notes, and sometimes also wing and bill snaps.
识别特征
The Senegal batis is a restless flycatcher-like small bird with the distinctive black, white and grey colours and plumage patterns which are typical of the batises. The adult male has a dark slate grey forehead and crown with a long, broad white supercilium which almost reaches the white nape patch. The face mask is glossy bluish-black. The mantle and upper back are slate grey tinged with brown, the lower back and rump are mottled grey, white and black. The feathers on the rump are long and this gives the rump a fluffy appearance, contrasting with the glossy blue-back uppertail coverts. The wings are brownish black with a white stripe along their length. The underwing coverts are black and the tail is black with white tipped and edged outer tail feathers. The underparts are white, except for the underwing coverts and thighs and the broad glossy blue-black breast band. Adult females are overall paler than males with dusky grey brown forehead and crown, a buff supercilium and nape patch and a black face mask, browner wings and a russet breast band, as well as rufous ting to the chin and upper throat. Juveniles are like duller females. The Senegal batis measures 10 cm (3.9 in) in length and weighs 8–11.4 g (0.28–0.40 oz).<p>The main call of the Senegal batis is a series of medium pitched double and triple note whistles which do not vary in pitch and are frequently introduced with buzzy notes.
分类信息
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the Senegal batis in his Ornithologie based on a specimen collected in Senegal. He used the French name Le gobe-mouche à poitrine rousse du Sénégal and the Latin Muscicapa Senegalensis pectore rufo. 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 in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the Senegal batis. Linnaeus included a brief description, coined the binomial name Muscicapa senegalensis and cited Brisson's work. The species is now placed in the genus Batis that was introduced by the German zoologist Friedrich Boie in 1833. The species is monotypic.

Brown Bush Warbler
Locustella luteoventris
Shy inhabitant of scrubby areas in the middle to upper reaches of hilly and montane regions. Dark brown with a white throat and grayish belly. Long tail usually held horizontally, seldom cocked up. Rarely ventures out into the open except when singing; even then, it usually sings from partial cover. Song is a rattling series of dry, repeated notes, somewhat like clattering machinery.
Black-billed Cuckoo
Coccyzus erythropthalmus
Slender, long-tailed bird more often heard than seen. White below and brown above, with black bill. Separated from Yellow-billed Cuckoo by bill color, uniformly brown outer wings (not rufous) and smaller white spots on underside of tail. Feeds mainly on caterpillars and other insects. Found mostly in deciduous woodlands, especially areas with thick secondary growth. Often sits motionless for long periods of time and is difficult to spot. Listen for its song, a repeated series of soft "cu-cu-cu" notes.
Orinoco Piculet
Picumnus pumilus
This scarce piculet is known only from a few locations in the humid lowlands of eastern Colombia, southern Venezuela, and northwestern Brazil. Its underparts are entirely barred, but upperparts are plain, lacking the barring shown by the otherwise very similar Lafresnaye’s Piculet. Inhabits light woodland and forest edge, and not found inside tall rainforest. Song is a high pitched “seep, seep, seep”, though sometimes only one or two notes are given. Call is a short, erratic trill.
