African Palm Swift
Cypsiurus parvus
A very slender gray-brown swift with a long, deeply forked tail that is often held closed, making it look needle-like and pointed. The erratic flight pattern, with frequent direction changes and rapid wingbeats on long, scythe-shaped wings, is distinctive. Less gregarious than other swifts; usually found in pairs or small flocks, and association with other swallows and swifts is usually only fleeting. Forages over a wide variety of habitats with palms, including savanna, coastal scrub, towns, villages, cultivated areas, forest edge, and clearings, from sea level up to 1800 meters of elevation, preferring lowlands. Nests and roosts in palms and uses its tiny legs with hook-like claws to cling to the undersides of fronds. Gives a high-pitched, metallic “tre-tit-tit-tit-tit-tit-tit-tit” call, solitarily or in unison with others. Separated from other swifts by its longer and thinner tail.
Identification
This 16 cm long species is mainly pale brown in colour. It has long swept-back wings that resemble a crescent or a boomerang. The body is slender, and the tail is long and deeply forked, although it is usually held closed. The call is a loud, shrill scream. Sexes are similar, and young birds differ mainly in their shorter tails. Palm swifts have very short legs which they use only for clinging to vertical surfaces, since swifts never settle voluntarily on the ground.

Behavior
These swifts spend most of their lives in the air, living on the insects they catch in their beaks. Palm swifts often feed near the ground. They drink on the wing. It is a common resident breeder in tropical Africa. The down and feather nest is glued to the underside of a palm leaf with saliva, which is also used to secure the usually two eggs. This is a fast flying bird of open country, which is strongly associated with oil palms but is also found in wooded savannah, thornbush and cultivated land.

Ringed Teal
Callonetta leucophrys
Small distinctive duck. Males have a pinkish breast that is spotted in black with a rich chestnut wing and a metallic green patch on the flight feathers. Note the blue bill. Females have a striking brown-and-white face pattern, and are mostly brown above and mottled or banded brown below. In flight shows dark wings with white-and-green bands. Occurs in marshes and swamps with abundant vegetation; can be even seen perched on fences or low trees.
Red-legged Cormorant
Poikilocarbo gaimardi
Attractive coastal cormorant; locally fairly common in Humboldt Current. Often seen perched on jetties, inshore rocks, and cliffs associating readily with Guanay Cormorant, pelicans, boobies, and Inca Terns. Mainly feeds in small groups or as scattered individuals, not in huge dense rafts like Guanay Cormorant. Note distinctive big white neck patch, pale scalloping on upperparts, brightly colored bill, and red legs. Immature has more muted pattern than adult.
Carp's Tit
Melaniparus carpi
A black tit with a mostly white wing and outer tail. The sexes are similar, but females are slightly duller and browner. Found in arid savanna and mopane woodland. Usually in pairs or small groups, which are loud and conspicuous. Call is a classic tit “chee-chi-chi-chi-chi,” raspy and often repeated. Overlaps very locally with the very similar Southern Black-Tit in northern Namibia. Carp’s Tit can be identified by its all-black rather than white-barred undertail, and by having more white in the wing.
