Striated Heron Butorides striata: The most common heron throughout our area. Note that birds from
North America have been split and now referred to as the Green Heron.
Western Cattle Egret Bubulcus ibis: Common and widespread in open areas. The nominate race of
this species apparently invaded South America in the late 19th century, one of the most
rapid avian range expansions in historic times.
Cocoi Heron (White-necked H) Ardea cocoi: A few birds encountered along the Rio Solimões, one
in the Anavilhanas and a few in Roraima.
Great Egret Casmerodius albus: Large numbers along the Rio Solimões and other sites with aquatic
environments. Note that at present this species is sometimes placed within the genus
Ardea.
Capped Heron Pilherodius pileatus: Up to seven seen along the Igarape Januari and a few in
Roraima.
Snowy Egret Egretta thula: Very common on Marchantaria and along the Careiro road.
THRESKIORNITHIDAE
Green Ibis Mesembrinibis cayennensis: One seen in at Janauari and another in Mindu Park.
Buff-necked Ibis Theristicus infuscatus : One seen along the Careiro road was an extralimital record.
Common in the savannas of Roraima.
CICONIDAE
Wood Stork Mycteria mycteria: A few in Roraima.
Maguari Stork Ciconia maguari: Up to 30 in Roraima.
Jabiru Jabiru mycteria: Up to 20 in Roraima.
CATHARTIDAE
Turkey Vulture Cathartes aura: Common throughout the trip in open and urban areas. Although
traditionally placed with raptors modern studies indicate a more convoluted origin
placing them nearer storks. No doubt the ongoing taxonomic research will again revise
this.
Lesser Yellow-headed Vulture Cathartes burrovianus: Numerous on Marchantaria and along the
Solimoes.
Greater Yellow-headed Vulture Cathartes melambrotus: The commonest vulture of forested areas
north of Manaus and around São Gabriel.
Black Vulture (American B V) Coragyps atratus: Abundant throughout the tour.
King Vulture Sarcoramphus papa: One seen at Iracema falls. The specific name papa is Latin for
bishop and the name refers to the immaculate white plumage of the adult.
ACCIPITRIDAE
Osprey Pandion haliaetus : A couple seen along the Rio Negro.
Grey-headed Kite Leptodon cayanensis: A single bird seen along the Rio Negro. A somewhat thinly
distributed species.
Swallow-tailed Kite (American S-t K) Elanoides forficatus: A big group during our second visit to the
INPA Tower.
Pearl Kite Gampsonyx swainsonii: Two seen in Roraima.
White-tailed Kite Elanurus leucurus: A few in Roraima.
Snail Kite (Everglade K) Rostrhamus sociabilis: Numerous on Marchantaria and along the Careiro
Road. This species feeds almost exclusively on apple snails (Pomacea sp.), apparently
without ill effect.
Slender-billed Kite Rostrhamus hamatus: One seen along the Careiro road.
Double-toothed Kite Harpagus bidentatus: Two birds seen at the INPA Tower and another pair along
the Cucui road.
Plumbeous Kite Ictinia plumbea: Several birds seen north of Manaus and other on Marchantaria.
