The ZooChat Photographic Guide To The Piciformes (part I) - Toucans

[TeaLovingDave]

This post was written in July 2021, but has been added here retrospectively in order to form an introduction to the three segments of the following Photographic Guide To The Piciformes, and explain the somewhat unusual format.

This thread was initially a stand-alone Photographic Guide to the Toucans undertaken by @Great Argus and approved by the moderation team; we invited him to tackle the entire Piciformes but his familiarity and comfort-level with the remaining families within the group was insufficient and he demurred. However, this left us with the dangling issue of precisely how to handle the Piciformes as a whole, as we felt it would be disrespectful to take over within the original thread or to cover toucans again in the future, but equally a Piciformes thread or threads which omitted toucans would feel somewhat awkward.

To that end, on discussing the matter with @Great Argus this evening I have renamed this thread to encompass the Piciformes as a whole, and added this supplementary post, but the content of the thread will stand alone. A pair of further threads will follow in order to complete the overall Photographic Guide To The Piciformes as follows; a thread covering the various families of barbet, the puffbirds, jacamars and allies; and a thread covering woodpeckers and honeyguides

 

[Great Argus]

The toucans form a well known family within the Piciformes. While the family has been quite stable at genus level, there have been many recent splits at species level. A fair few of these splits are contested, and some separable only by range. HBW recognizes fifty species in five genera.

The family ranges from central Mexico in the north to northern Argentina and Uruguay in the south. All but the Toco Toucan are forest-dwellers.

And now, the Ramphastidae.

Ramphastidae


Ramphastidae contains five genera, with 50 species recognized by HBW.


Ramphastos - Typical Toucans

Aulacorhynchus - Green Toucanets

Andigena - Mountain-toucans

Selenidera - Dichromatic Toucanets

Pteroglossus - Aracaris

Ramphastos - Typical Toucans


Toco Toucan Ramphastos toco (Müller, 1776)

Patchily distributed in the Guyanas, along the lower Amazon River, widespread in central South America below the Amazon rainforest to northern Argentina and barely Uruguay.

Polytypic, two subspecies recognized tentatively with poor differentiation. albogularis said to be smaller than nominate, with a whiter throat.

Yellow-throated Toucan Ramphastos ambiguus (Swainson, 1823)

Also known as Swainson’s Toucan, Chestnut-mandibled Toucan

Eastern Honduras through down to north-western Venezuela, along west slope of Andes into central Peru.

Polytypic, three subspecies. R. brevis has been considered a subspecies, R. a. swainsonii sometimes elevated to full species. Differences between races slight, however not believed to overlap in range.

Cuvier’s Toucan Ramphastos cuvieri (Wagler, 1827)

Much of central South America, east of Andes from central Colombia south to northern Bolivia, east to central Brazil.

Polytypic, two subspecies. Species is frequently merged with R. tucanus, HBW considers it valid so including here. Race inca sometimes merged with cuvieri, does intergrade.

R. c. cuvieri
Possible photo of this subspecies in the gallery, however the distinguishing characters of beak and rump are unable to ascertain.

R. c. inca

Red-billed Toucan Ramphastos tucanus (Linnaeus, 1758)

Central Venezuela through Guyanas and north-central Brazil.

HBW considers it to be monotypic, although often merged with R. cuvieri. Several forms proposed, none considered valid by HBW.

Keel-billed Toucan Ramphastos sulfuratus (Lesson, 1830)

Also known as Rainbow-billed Toucan.

East central and south Mexico down the Atlantic side through Honduras, continues throughout Nicaragua down to far northern Colombia and barely north-western Venezuela.

Polytypic, two weakly defined subspecies that intergrade where they meet. Nominate is larger, with a larger portion of red on the end of the bill; no or very little red around the yellow throat.

Choco Toucan Ramphastos brevis (Meyer de Schauensee, 1945)

West slope of Andes from just below Panama border down through Colombia and Ecuador. Range does overlap that of R. ambiguus, with which species has often been considered conspecific.

Monotypic, although superficially similar to R. ambiguus and often considered conspecific. Voice, smaller size, and bill size/color basis for separation.

Photo by @ronnienl

Citron-throated Toucan Ramphastos citreolaemus (Gould, 1844)

North-central and north-eastern Colombia into north-western Venezuela.

Monotypic, however belongs to a species group with R. culminatus, R. vitellinus, and R. ariel. These four are commonly considered conspecific under R. vitellinus. Morphology is best separation, although species overlap produces hybrids.

This species is not represented in the gallery.



Yellow-ridged Toucan Ramphastos culminatus (Gould, 1833)

East of Andes from central Colombia south to Bolivia, east to just short of Guyanas and central Brazil.

Monotypic, though belonging to the “vitellinus” species group. A few described forms now considered hybrids.

Photo by @ronnienl

Channel-billed Toucan Ramphastos vitellinus (Lichtenstein, 1823)

Central Venezeula and Guyanas into north-central Brazil.

Monotypic, belongs to the “vitellinus” species group. Two previously described forms now considered hybrids with culminatus.

Photo by @Hix

Ariel Toucan Ramphastos ariel (Vigor, 1826)

Two disjunct populations; one in central Brazil, the second along the Atlantic coast of Brazil from E Pernambuco S to Santa Catarina.

Monotypic despite two disjunct populations. Belongs to the “vitellinus” group, though more distinctive than some.

Red-breasted Toucan Ramphastos dicolorus (Linnaeus 1766)

Also known as Green-billed Toucan.

Eastern Paraguay through southern Brazil.

Monotypic.

Fantastic thread - long overdue! Thanks

 

[ThylacineAlive]

Great thread! Couple of points, though:

1) The Selenidera toucanet at Emerald Forest actually is a langsdorffi
2) The Chestnut-Eared Aracari are DWA and Emerald Forest are the nominate subspecies.

Thanks Thylo!

Interesting that the Selenidera is a langsdorffi, they have it as reinwardtii on their site. Since they do separate the Emerald Toucanet (even if as subspecies of Emerald) I chose to follow it. My mistake, I tried to avoid mistakes like that.
Thanks, I was having difficulty finding confirmation of nominate subspecies.

Yeah I originally had it down as a reinwardtii as well, but those have a very obvious bright red bill whereas the bill on the photographed individual is identical to that of a langsdorfii.

No problem

Great Job!
This thread makes me even more determined to see an actual toucan...

Lettered Aracari Pteroglossus inscriptus (Swainson, 1822)

Central Brazil from the Atlantic Ocean across into central Bolivia; a disjunct population in eastern Brazil in Pernambuco and eastern Alagoas.

Monotypic.

Photo by @savethelephant

This individual is not a true lettered aracari- it has a black lower mandible, which is a key feature of Humboldt’s. I suspect the individuals at PPZ could be hybrids between the two, but this is not a lettered aracari (and as far as I can tell there are no photos in the gallery of one).

P. t. torquatus

This isn’t a collared aracari, it’s a pale-mandibled aracari- a key identifying factor again being black on the lower mandible.

Pictures of these subspecies are in the Ecuador-Wildlife section

 

[Erythrogaster]

What is the evidence that the bird in the photo is A. p. virescens?

The bird labelled as A. a. albivitta is Aulacorhynchus prasinus, the bird has a white not grey/blue throat and lacks the orange orbital skin. This photo was taken at Emerald Forest from the looks of things and that collection never kept the former.

The bird labelled as Pteroglossus inscriptus is a pure P.humboldti. Obtained from the offspring of the original import.

Emerald Forest, yes.. They referred to the bird as a "White-Throated Toucanet" and explained that it was split off from A. prasinus.

~Thylo

 

[Erythrogaster]

The coloration of the bill isn't correct from A.a.albivitatta. A glance at their website confirms this is A.p.prasinus.
