ORIOLES AND BLACKBIRDS -
ICTERIDAE - PART I
Oropendolas
to Oriole Blackbird
 |
Russet-backed
Oropendola
Psarocolius angustifrons
angustifrons
Lumbaqui, Sucumbíos province, Ecuador.
One of the dullest of the family (though some of the other
races are more brightly colored, see below). They are very common
in NW South America in both the Andes and Amazon, where they form
large nesting colonies. This bird is in the middle of it's
display, where it throws itself forward, lifts its crest &
wings, and emits a wierd gurgling noise. (S5) |

Russet-backed
Oropendola
Psarocolius
angustifrons angustifrons
Napo Wildlife Center, Orellana province, Ecuador.
This is some interesting display behavior that I haven't
seen before. The bird was perched in a nesting tree with many
other individuals around, but it did not seem to be directing
this display to anyone in particular. (D2) |
 |
Russet-backed
Oropendola
Psarocolius angustifrons
salmoni
RNA Arrierito Antioqueño, Anorí, Antioquia
department, Colombia.
The racial variation in the species is pretty amazing.
This is the subspecies occurring in the western and central Andes
of Colombia, looking completely different from the nominate race
in the first two photos. Some people have suggested that some of
the races deserve full species status, but I don't think anyone
has done a serious study on the species. (D3) |

Green Oropendola
Psarocolius viridis
Yasuní Research Station, Orellana province, Ecuador.
A widespread oropendola in the Amazon and Guianan regions.
(S6) |
 | Crested Oropendola Psarocolius decumanus maculosus Pousada Piuval, Pantanal, Mato Grosso state, Brazil. A common species ocurring from Panama south to Brazil and northern Argentina. (S6) |
 |
Montezuma
Oropendola
Psarocolius
montezuma
Arenal Observatory Lodge, Alajuela province, Costa Rica.
The only oropendola through most of Central and Middle
America, and arguably the prettiest of them all.
(S5) |

Montezuma
Oropendola
Psarocolius
montezuma
La Selva OTS, Heredia province, Costa Rica.
Another shot of one feeding on nectar from an Erythrina tree. (D2) |
 |
Olive Oropendola
Psarocolius bifasciatus
yuracares
Yasuní Research Station, Orellana province, Ecuador.
These huge oropendolas can be half a meter long. Their
sheer size combined with striking coloration and bare facial skin
make them a spectacular bird. They are restricted to the Amazon
basin, and an alternate name is "Amazonian Oropendola".
(S6) |
 |
Casqued
Oropendola
Clypicterus oseryi
Yasuní Research Station, Orellana province, Ecuador.
An odd, small oropendola restricted to the western Amazon,
mainly in Peru and Ecuador. (S6) |
 |
Solitary Black
Cacique
Cacicus solitarius
Reserva Biológica de Saltinho, Pernambuco, Brazil.
This species gets its name from the fact that it does not
occur in flocks like most other caciques. (S6) |
 |
Yellow-rumped
Cacique
Cacicus cela cela
Napo Wildlife Center, Orellana province, Ecuador.
An abundant bird though the Amazon region, and a few other
places in northern South America. Like oropendolas, they form big
nesting colonies, often in the same trees. They are accomplished
mimics, and it's fun to listen to them in the nesting trees,
doing everything from Roadside Hawk to Dwarf Tyrant-Manakin.
(D2) |
 |
Red-rumped
Cacique
Cacicus haemorrhous
affinis
Estação Veracruz, Porto Seguro, Bahia state,
Brazil.
Here's a pair building a nest in an Atlantic Forest area
in Brazil. They are often rather common in the Atlantic Forest,
but in the Amazon region, where they occur together with
Yellow-rumped Cacique (C. cela), they are generally much less
common and often local. (D3) |
 | Golden-winged Cacique Cacicus chrysopterus Intervales State Park, São Paulo State, Brazil. (S6) |
 |
Yellow-billed
Cacique
Amblycercus holosericeus
holosericeus
North of Mapastepec, Chiapas state, Mexico.
One of the shiest members of this family, usually staying
in dense cover. It occurs in a wide range of habitats, from humid
lowlands of Mexico to bamboo thickets in the high Andes.
(S5) |
 |
Venezuelan
Troupial
Icterus icterus
icterus
Bruzual, Apure state, Venezuela.
The national bird of Venezuela, and I can certainly
respect that choice. Beautiful to look and with a lovely song as
well. It also occurs in Trinidad and extreme NE Colombia.
(D3) |
 |
Orange-backed
Troupial
Icterus croconotus
strictifrons
Pixaim, Mato Grosso state, Brazil.
They were bathing at the edge of the river, but
unfortunately flew away before we could get closer.
(S5) |
 | Epaulet (Moriche)
Oriole
Icterus cayanensis
chrysocephalus
Yasuní Research Station, Orellana province, Ecuador.
(S6) |
 |
Epaulet (Moriche)
Oriole
Icterus cayanensis
chrysocephalus
Iwokrama Field Station, Region 8, Guyana.
(D3) |
 | Variable Oriole Icterus pyrrhopterus pyrrhopterus Iguazú National Park, Misiones province, Argentina. Recently split from the previous species, due to differences in shape, habitat, and behavior. See http://www.museum.lsu.edu/~remsen/SACCprop418.html. Shoulder color is variable, leading to its English name. (S6) |
 |
Baltimore Oriole
Icterus galbula
Rancho Naturalista, Cartago province, Costa
Rica.
A familiar bird to North Americans. Here it's on it's
wintering grounds enjoying the pleasant climate of the Costa
Rican foothills. (D3) |
 |
Altamira Oriole
Icterus
gularis gularis
Zipolite, Oaxaca state, Mexico.
(S5) |
 |
Yellow Oriole
Icterus nigrogularis
nigrogularis
Annai, Region 9, Guyana.
An oriole of dry areas of far northern South American
between Panama and the Amazon river. (D3) |
 |
Mountain Grackle
Macroagelaius
subalaris
Reserva Reinita Cielo Azul, Santander department, Colombia.
A super-rare bird of high cloudforest in the eastern Andes
of Colombia. It is closely related to Golden-tufted Grackle
(M. imthurni) of the
Tepui region, with a very similar voice, but due to the huge
distance separating them they are usually kept as separate
species. This is one of the only photos of this bird ever taken
in the wild. (D3) |
 |
Oriole Blackbird
Gymnomystax
mexicanus
Calabozo-San Fernando highway, Guárico state,
Venezuela.
This one has a rather odd distribution. Throughout the
Amazon region, it is found along major rivers, especially on
river islands. However, it is also common in the Llanos, where it
is found in open ranchland not necessarily near rivers. With the
clearance of the Amazon rainforest, one would expect it to expand
it's range south and east, but I have personally noticed that
happening. (D3) |
