Name

Thraupidae

The tanagers (sg. pronounced /ˈtænədʒər/) comprise the bird family Thraupidae, in the order Passeriformes. The family has an American distribution.

There were traditionally about 240 species of tanagers, but the taxonomic treatment of this family's members is currently in a state of flux. As more of these birds are studied using modern molecular techniques it is expected that some genera may be relocated elsewhere. Already species in the genera Euphonia and Chlorophonia, which were once considered part of the tanager family, are now treated as members of Fringillidae, in their own subfamily (Euphoniinae). Likewise the genera Piranga (which includes the Scarlet Tanager, Summer Tanager, and Western Tanager), Chlorothraupis, and Habia appear to be members of the Cardinal family[1], and have been reassigned to that family by the AOU.

Description

Tanagers are small to medium-sized birds. The shortest-bodied species, the White-eared Conebill, is 9 cm (3.8 in) long and weighs 7 grams, barely smaller than the Short-billed Honeycreeper. The longest, the Magpie Tanager is 28 cm (11 in) and weighs 76 grams (2.7 oz). The heaviest is the White-capped Tanager which weighs 114 grams (4 oz) and measures about 24 cm (9.5 in)! Both sexes are usually the same size and weight. Tanagers are often brightly colored, but some species are black and white. Birds in their first year are often duller or a different color altogether. Males are typically more brightly coloured than females.

Most tanagers have short, rounded wings. The shape of the bill seems to be linked to the species' foraging habits.

Distribution

Tanagers are restricted to the New World and mainly to the tropics. About 60% of tanagers live in South America, and 30% of these species live in the Andes. Most species are endemic to a relatively small area.

Behaviour

Most tanagers live in pairs or in small groups of 3-5 individuals. These groups may consist simply of parents and their offspring. Birds may also be seen in single species or mixed flocks. Many tanagers are thought to have dull songs, though some are elaborate.

Diet

Tanagers are omnivorous, and their diet varies from genus to genus. They have been seen eating fruits, seeds, nectar, flower parts and insects. Many pick insects off branches. Other species look for insects on the underside of leaves. Yet others wait on branches until they see a flying insect and catch it in the air. Many of these particular species inhabit the same areas, but these specializations alleviate competition.

Reproduction

The breeding season begin in March through until June in temperate areas and in September through October in South America. Some species are territorial while others build their nests closer together. There is little information on tanager breeding behavior or whether they are monogamous or polygamous. Males show off their brightest feathers to potential mates and rival males. Some species' courtship rituals involve bowing and tail lifting.

Most tanagers build cup nests on branches in trees. Some nests are almost globular. Entrances are usually built on the side of the nest. The nests can be shallow or deep. The species of the tree they choose to build their nest in and the nest's position varies among genera. Most species nest in an area hidden by very dense vegetation. There is still no information on the nests of some species.

The clutch size is 3–5 eggs. The female incubates the eggs and builds the nest, but the male may feed the female while she incubates. Both sexes feed the young. Five species have helpers assist in feeding the young. These helpers are thought to be the previous year's nestlings.

Systematics

Phylogenetic studies suggest the true tanagers form three main groups two of which consist of several smaller, well-supported clades.[2] The list below is an attempt using information gleaned from the latest studies to organise them into coherent related groups, and as such may contain groupings not yet accepted by or are under review by the various ornithological taxonomy authorities.[3]

Group 1

Mainly dull-coloured forms
Slaty Finch, Haplospiza rustica

a) Conebill and flowerpiercer group (Also contains Haplospiza, Catamenia, Acanthidops, Diglossa, Diglossopis, Phrygilus and Sicalis[4] traditionally in the Emberizidae)[5] This group despite having a rather varied bill morphology shows marked plumage similarities. Most are largely grey, blue, or black, and numerous have rufous on the underparts:

* Genus Conirostrum – typical conebills (10 species)
* Genus Oreomanes – Giant Conebill
* Genus Xenodacnis – Tit-like Dacnis
* Genus Catamenia (3 species)
* Genus Diglossa – typical flowerpiercers (14 species)

* Genus Haplospiza (2 species). Paraphyletic with 2 species of sierra-finch Phrygilus[6]
* Genus Acanthidops – Peg-billed Finch
* Genus Phrygilus - sierra-finches (11 species)[7]
* Genus Sicalis – yellow-finches (12 species). Paraphyletic with Phrygilus[8]

b) True seedeaters. Traditionally placed in Emberizidae. These genera share a particular foot-scute pattern which suggests that they may form a monophyletic group[9]:

g) Grass & Pampa-finches. Relationships within Thraupidae uncertain but together form a well-supported clade[8]:

* Genus Emberizoides (3 species)
* Genus Embernagra (2 species)


h) A miscellaneous and likely polyphyletic group of unplaced "tanager-finches" (which may or may not include the species called Tanager-finch) whose members when studied will no doubt be relocated to other clades:

* Genus Melanodera (2 species)
* Genus Rowettia – Gough Island Finch
* Genus Nesospiza (2 species)
* Genus Gubernatrix – Yellow Cardinal
* Genus Idiopsar – Short-tailed Finch
