The values obtained in this study can thus be used by veterinarians in wildlife facilities and in the wild, for research and diagnosis that can be used in curing or treating closely related species in the genus Penelopides, Buceros, and Anthraceros.
Rufous hornbill is compared with the values of Buceros rhinoceros coming from the same study since they are the same in genus and only differ in species.
Tropical hornbills (Aceros cassidix, Aceros undulatus, and Buceros hydrocorax) use ballistic transport to feed with their large beaks.

Recent re-examination of the holotype (= monotype) of Grewingkia buceros (Eichwald, 1856) by the present author has revealed that this species is not synonymous with Kiaerophyllum kiaeri Wedekind, 1927 as earlier thought by Neuman (1969, pp.

(18) Few tumors have been described in species within the order Bucerotiformes (hornbills), such as a hepatocellular adenoma in a Luzon hornbill (Penelopides manillae) (23) and a squamous cell carcinoma in a great hornbill (
Buceros bicornis), (24) but to our knowledge, this is the first report of seminoma in hornbills.
Instead, what the Inquirer saw at the Batangas aviary was one Rufous hornbill (
Buceros hydrocorax), an endemic species.
Cryptosporidium galli was isolated from chickens and primarily affects the proventriculus, and infections have also been reported in turquoise parrots (Neophema pulchella), flamingos (Phoenicopterus ruber), hornbills (
Buceros rhinoceros), and certain passerine birds.
The birds evaluated were 3 rhinoceros hornbills (
Buceros rhinoceros), a wrinkled hornbill (Aceros corrugatus), and an Indian pygmy goose that was the mate of the bird in Case 1.
An earlier attempt with PDT on a great hornbill (
Buceros bicornis), (8) also with squamous cell carcinoma, described a transient limb paralysis, which was attributed to an ischemic or thromboembolic event because of vasoconstrictive effects of PDT.
SSCs have been described in various anatomic regions and in various avian species, including white storks (Ciconia ciconia), (2) Montagu harriers (Circus pygargus), (3) hornbills (Buceros bicornis), (4,5) domestic chickens, (6-8) and psittacine bird species, including cockatiels (Nymphicus hollandicus), (9) budgerigars (Melopsittacus undulatus), (10) Buffon macaws (Ara ambigua), (11) and salmon-crested cockatoos (Cacatua moluccensis).
