Genera

Hornbills (family Bucerotidae) are a group of birds characterized by a long, down-curved bill, sometimes with a casque on the upper mandible. The Abyssinian Ground-hornbill or Northern Ground-hornbill, Bucorvus abyssinicus, is one of two species of Ground-hornbill. Chordates ( Phylum Chordata) are a group of Animals that includes the Vertebrates together with several closely related Invertebrates Birds ( class Aves) are bipedal endothermic ( Warm-blooded) Vertebrate animals that lay eggs.

Many of the birds are now endangered. Some species of hornbill are protected in Malaysia. Both the common English and the scientific name of the family refer to the shape of the bill, "buceros" being "cow horn" in Greek.

The kidneys are complicated organs that have numerous biological roles Hornbills are the only birds in which the first two neck vertebrae (the axis and atlas) are fused together; this probably provides a more stable platform for carrying the bill.

Composition and relationships

The Bucerotidae include some 57 living species, about 10 of them endemic to the southern part of Africa. In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank. Their distribution ranges from Africa south of the Sahara through tropical Asia to the Philippines and Solomon Islands. The Sahara (الصحراء الكبرى aṣ-ṣaḥrā´ al-kubra, "The Great Desert" is the world's largest hot Desert and the world's second largest The Philippines ( Filipino: Pilipinas, officially known as the Republic of the Philippines (fil ''Republika ng Pilipinas'' RP The Solomon Islands is a country in Melanesia, east of Papua New Guinea, consisting of nearly one thousand islands Most are arboreal birds of dense forest, but the large ground-hornbills (Bucorvus), as their name implies, are terrestrial birds of open savanna. The Ground-hornbills (Bucorvinae are a subfamily of the Hornbill family Bucerotidae with a single genus Bucorvus and two extant species A savanna or savannah is a Tropical or Subtropical Grassland or Woodland Ecosystem.

There are two subfamilies: the Bucorvinae contain the 2 ground-hornbills in a single genus, whereas the Bucerotinae contain all other taxa.

The trogons and quetzals are Birds in the order Trogoniformes which contains only one family the Trogonidae. All that can be said with reasonable certainty is that placing the hornbills outside the Coraciiformes and the trogons inside would be incorrect.

Hornbills are omnivorous birds, eating fruit, insects and small animals. The Southern Ground-hornbill, Bucorvus leadbeateri or cafer, is one of two species of Ground-hornbill and is the largest species of Hornbill Grasshoppers are Insects of the suborder Caelifera in the order Orthoptera. Omnivores (from Latin omne all everything vorare to devour are species that eat both Plants and Animals as their primary They cannot swallow food caught at the tip of the beak as their tongues are too short to manipulate it, so they toss it back to the throat with a jerk of the head. They range in size from the Black Dwarf Hornbill (Tockus hartlaubi), at 102 grams (3. UserPolbot. -->The Black Dwarf Hornbill ( Tockus hartlaubi) is a species of Hornbill in the Bucerotidae 6 oz) and 30 cm (1 foot), to the Southern Ground-hornbill (Bucorvus leadbeateri), at up to 6. The Southern Ground-hornbill, Bucorvus leadbeateri or cafer, is one of two species of Ground-hornbill and is the largest species of Hornbill 2 kg (13. 6 lbs) and 1. 2 m (4 feet). Males are about 18% larger than females on average, and some species have sexual dichromatism. Sexual dimorphism is the systematic difference in form between individuals of different Sex in the same Species. In the Abyssinian Ground-hornbill, for example, pure blue skin on the face and throat denotes an adult female, and red and blue skin denotes an adult male.

Hornbills generally form monogamous pairs. Monogamy is the custom or condition of having only one mate in a Relationship, thus forming a Couple. The female lays up to six white eggs in existing holes or crevices, either in trees or rocks. Before incubation, the females of all Bucorvinae—sometimes assisted by the male—begin to close the entrance to the nest cavity with a wall made of mud, droppings and fruit pulp. When the female is ready to lay her eggs, the entrance is just large enough for it to enter the nest, and after she has done so, the remaining opening is also all but sealed shut. There is only one narrow aperture, big enough for the male to transfer food to the mother and the chicks. During the incubation period the female undergoes a complete moult. In Biology, moulting (or molting, also known as shedding or for some species Ecdysis) signifies the manner in which an animal routinely When the chicks and the female are too big to fit in the nest, the mother breaks out, then both parents feed the chicks. In some species the mother rebuilds the wall, whereas in others the chicks themselves rebuild the wall unaided. The ground-hornbills are conventional cavity-nesters instead.
