Longueur totale du corps : environ 84 cm, envergure d'environ 120cm. Poids : de 1250 à 4000 g.
Diagnose
La tête, le cou, le corps et la queue sont noir / brunâtre avec des reflets verts et pourpres. Le plumage est identique chez les deux sexes mais le mâle porte une courte huppe sur la nuque. Les couvertures sus et sous-alaires sont blanches. Les rémiges sont noires. Le bec est noir tacheté de blanc dans la plus grande partie, rosé dans la partie subterminale. Le mâle possède une protubérance à la base du bec et une zone de peau nue faciale qui sont noirâtres parfois rougeâtres. Ces deux particularités sont absentes chez les femelles. Les pattes et les pieds sont noir grisâtre.
Détermination
Simple au niveau spécifique.
Espèces proches
Il est difficile de le confondre par sa masse imposante et son plumage presque entièrement noir.
Période d'observation
On peut l'observer toute l'année en Guadeloupe et principalement le soir ou à l'aube.
Biologie – éthologie
Cet oiseau apprécie les milieux aquatiques et fréquente les lagunes, les lacs, les marais et les rivières lentes des forêts tropicales de plaine. Bien qu'il préfère les eaux douces, on le rencontre aussi parfois à la saison sèche dans les marais et les lagunes saumâtres des côtes. Malgré une grande fertilité, le taux de réussite des nichées est peu important. Seuls 2 ou 3 œufs parviennent généralement à éclore.
Biogéographie et écologie
Il est présent naturellement de l'Amérique du Sud jusqu'au Mexique, ainsi qu'en Guyane et dans les Antilles. On peut également le retrouver à l'état « semi-sauvage » dans certains états des USA où il vit près des habitations. Sa domestication est aisée.

The map presents a summary at the 10 x 10 km grid of the observation data for the species transmitted to the SINP. These data have been subjected to validation filters.

Current distribution in metropolitan France
The map presents a reference distribution layer of the species at the scale of departments and marine sectors. The presence and absence data were established by expertise within a network of partners. This reference distribution is used in the validation process of the SINP data at the INPN level.

Certain presence
Corresponds to a report on the basis of at least one observation proved within a period of 10 years (20 years for little-known invertebrates) preceding the year and no presumption of extinction since obtaining the last data nor doubt on reproductive and implemented nature of this population. For migratory species, the presence indicated concerns areas of reproduction.
Probable presence
This status is based on one or more of the following criteria:
search of species incomplete but presence of supportive environments;
ecology of the species consistent with the hypothesis of his presence;
the last reliable sighting is older than 10 years compared to the reference date, no recent specific research and no presumption of extinction from that date [vertebrates, invertebrates and plants well studied (rhopalocera, grasshoppers, dragonflies ...)] ;
the last reliable observation being older than 20 years, no recent specific research and no presumption of extinction from that date [poorly known taxa: fungus, many invertebrates...].
Probable or certain absence
This point covers the absence, more difficult by nature to demonstrate than presence. This status is based on one or more of the following criteria:
intensive but unsuccessful targeted research;
lack of adequate environments;
unobserved species while its presence is easily detected;
unlikely presence for historical or biogeographical reasons.
This status must be assigned to a department in which the presence of the species is casual.
Absence due to a proven extinction
Particular case of absence due to a proven extinction less than a half century ago (older disappearances are treated as "no probable or definite").
No information
In the state of knowledge, we can not comment on the presence or absence in the current department. This is the default status when not comprised in one of the previous categories or whenever there is doubt.
