The Senegal Parrot (Poicephalus senegalus) is a Poicephalus parrot which is a resident breeder across a wide range of west Africa. It makes migrations within west Africa, according to the availability of the fruit, seeds and blossoms which make up its diet. It is considered a farm pest in Africa, often feeding on maize or millet. It is popular in aviculture.

There are three subspecies. They do not differ in behaviour, but only in the colour of the "vest". In the pet trade, the nominate subspecies is the most common though all three are raised and sold as pets.

* Poicephalus senegalus senegalus (the nominate subspecies): this subspecies has a yellow vest; its native range includes southern Mauritania, southern Mali to Guinea and Lobos Island.
* Poicephalus senegalus mesotypus: this subspecies has an orange vest; its range is from eastern and northeastern Nigeria and Cameroon into southwest Chad.
* Poicephalus senegalus versteri: this subspecies has a deep-orange/red vest; its range is from the Ivory Coast and Ghana east to western Nigeria.

Senegal Parrots are birds of open woodland and savanna. With the exception of the Ring-Necked Parakeet, the Senegal is the only parrot inhabitant of the savanna woodlands and forest mossaic of West Africa. It is a gregarious species, continuously chattering with a range of whistling and squawking calls. Senegal Parrots live an average of approximately 25–30 years in the wild, and have been known to live for 50 years in captivity.

Senegal Parrots are about 23 cm long, weigh about 120 to 170 g. They have a relatively large head and beak for their overall size, and feathers form a short broad tail. Adults have a charcoal grey head, grey beak, bright yellow irises, green back and throat, and yellow underparts and rump. The yellow and green areas on a Senegal Parrot's front form a V-shape resembling a yellow vest worn over green. Young Juveniles have dark grey, almost black, irises, which change to light grey.

Senegal Parrots are not sexually dimorphic, but there are some hypotheses which sometimes might help to determine the gender of adult birds:

* The V-shape of the vest is usually longer in females; in females the green area extends down over the chest to between the legs, whereas in males the tip of the green area ends midway down the chest.
* The female's beak and head are generally slightly smaller and narrower than the male's.
* The under-tail covert feathers (short feathers under the base of the main tail feathers) are generally mostly yellow in the male and generally mostly green in the female.
* Males are generally, but not always, larger and heavier than female birds.

The Hoopoe (Upupa epops) is a colourful bird that is found across Afro-Eurasia, notable for its distinctive 'crown' of feathers. It is the only extant species in the family Upupidae. One insular species, the Giant Hoopoe of Saint Helena, is extinct, and the Madagascar subspecies of the Hoopoe is sometimes elevated to a full species. The English name is derived from Latin upupa, which imitates the cry of the bird.

The Hoopoe is classified in the Coraciiformes clade, a group that also includes kingfishers, bee-eaters, rollers, and woodhoopoes (forming a clade with this one according to Hackett et al. (2008). A close relationship between the Hoopoe and the woodhoopoes is also supported by the shared and unique nature of their stapes. In the Sibley-Ahlquist taxonomy, the Hoopoe is separated from the Coraciiformes as a separate order, the Upupiformes. Some authorities place the woodhoopoes in the Upupiformes as well.

The fossil record of the hoopoes is very incomplete, with the earliest fossil coming from the Quaternary. The fossil record of their relatives is older, with fossil woodhoopoes dating back to the Miocene and those of an extinct related family, the Messelirrisoridae, dating from the Eocene.

It is the only extant member of its family, although some treatments consider some of the subspecies as separate species. Several authors have separated the Madagascan subspecies (U. e. marginata) as a separate species, and also the resident African form U. e. africana. The morphological differences between the most commonly split subspecies, U. e. marginata, and the other subspecies are minor, and only U. e. marginata has distinctly different vocalisations. One accepted separate species, the Giant Hoopoe, U. antaios, lived on the island of St Helena but became extinct in the sixteenth century, presumably due to introduced species.

The Hoopoe is a medium sized bird, 25–32 cm long, with a 44–48 cm wingspan weighing 46-89 g. The species is highly distinctive, with a long, thin tapering bill that is black with a fawn base. The strengthened musculature of the head allows the bill to be opened when probing inside the soil. The hoopoe has broad and rounded wings capable of strong flight; these are larger in the northern migratory subspecies. The Hoopoe has a characteristic undulating flight, which is like that of a giant butterfly, caused by the wings half closing at the end of each beat or short sequence of beats.

The song is a trisyllabic "oop-oop-oop", which gives rise to its English and scientific names. In the Himalayas, the calls can be confused with that of the Himalayan Cuckoo (Cuculus saturatus) although the cuckoo typically produces four notes. Other calls include rasping croaks and hisses. A wheezy note is produced by females during courtship feeding by the male.

The Northern Carmine Bee-eater (Merops nubicus) is a near passerine bird in the bee-eater family Meropidae. Alternative common names include the Carmine Bee-eater or the Nubian Bee-eater.

It is native to Benin, Burkina Faso, Cameroon, the Central African Republic, Chad, the Democratic Republic of the Congo, Côte d'Ivoire, Eritrea, Ethiopia, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Liberia, Mali, Mauritania, Niger, Nigeria, Senegal, Sierra Leone, Somalia, Sudan, Tanzania, Togo and Uganda. It occurs as a vagrant in Burundi.

This species, like other bee-eaters, is a richly colored, slender bird, predominantly carmine in color, except for a greenish blue head and throat and distinctive black mask. This species has red eyes, a black, pointed, decurved beak, and elongated central tail feathers.

The sexes are similar in appearance, and the juveniles can be distinguished from adults by their lack of elongated central tail feathers and the pinkish brown coloration of their mantle, chest to belly, and flanks.
