THE WORLD BIRDS - An Online Bird Book
ICTERIDAE
The
Icterids are a group of small to medium-sized, often colorful birds, restricted to the
New World. Most species have black as a predominant plumage color, often enlivened by yellow, orange or red. The majority of icterid species live in the tropics, although there are a number of temperate forms. They inhabit a range of habitats, including scrub, swamp, forest, and savannah. Temperate species are migratory. Icterids are variable in size, and often display considerable sexual dimorphism. Their size varies 15-52 cm. One unusual adaptation shared is they can open their bills strongly rather than passively, allowing them to force open gaps to obtain otherwise hidden food. Some use their gaping motion to open the skins of fruit to obtain the soft insides, and have long bills adapted to the process. Others such as cowbirds have shorter stubbier bills for crushing seeds. orioles will drink nectar. The nesting habits of these birds are similarly variable.
The Icteridae are described in the following articles:
black birds,
caciques,
cowbirds,
grackles,
meadow lark, and
orioles.
Orioles
Order Passeriformes Family Icteridae
The
New World orioles of family
Icteridae,
genus Icterus are not related to
Old World orioles of family Oriolidae, but are strikingly similar in size, diet, behavior,
and their strongly contrasting plumage, a good example of convergent evolution. The males are typically black and yellow or orange, with white markings; the plumage of females and immature birds is duller. They are generally slender with long tails and a pointed bill. Most range from 18 to 25 cm long. The Venezuelan troupial can reach 27 cm long.
In
Icterus genus there are 29 species name orioles and 3 troupials. The troupials are named from a greek word that means troops which is appropriate because the troupials live in flocks. Even though the troupials and orioles are in the same genus, the troupials are very different in a their approach to nests. While the orioles all have woven elongated pouches for nests, the troupials doe not build their own next, instead they use an old one or evict a current owner. And they are fussy about the type of nest they use - the entryway should be covered. With such a difference between the orioles on troupials, perhaps they should not be in the same genus. Another minor difference is that all New World orioles have dark eyes while the troupials have yellow eyes.
Orioles and troupials mainly eat insects, and usually also nectar and fruit. Sliced whole fruit can be used to attract orioles to bird feeders and many species will also visit hummingbird feeders for the nectar. Chicks need high protein food and thus are fed mostly insects and spiders. The
Icterus species are do not require a specific habitats. Many like to be near water, none like dense forests, and quite a few like dry areas. Species nesting in areas with cold winters are
migratory.
