A new species of bulbul – Creme-eyed Bulbul

This species has only just been described – Creme-eyed Bulbul (Pycnonotus pseudosimplex Shakya et al.); it is one of the many cryptic species that have been previously overlooked. 

The species appears to be more closely related to the Gray-fronted Bulbul (Pycnonotus cinereifrons(Tweeddale)) from the island of Palawan, Philippines than to the White-eyed Bulbul (Pycnonotus simplexLesson) with which it shares its habitat on the Indonesian island of Borneo and which it closely resembles.

Levaillant’s Blue-tailed Lory

Levaillant’s Blue-tailed Lory is another mysterious lory ‚described‘ at the very beginning of the 19th century by François Le Vaillant on the basis of a single specimen (alive or dead?).

The bird is very similar in many aspects to the Red Lory (Eos bornea (L.)), a species that does not occur on the island of Borneo, Indonesia, but on several small islands within the Maluku island group, Indonesia, namely Ambon, Buru, Saparua, Seram, Haruku, and the Kai Islands.

The mysterious lory differs from the Red Lory actually only in its name-giving blue tail.

The bird was never scientifically described, and since F. Le Vaillant wasn’t a fan of C. von Linné‘s binominal nomenclature system, it was only ever named as ‚Le Perroquet Lori a queue bleue‘, as ‚The Lori Parrot with a blue tail‘.

Here is the important part of Levaillant’s ‚description‘.:

Le plumage général, c‘est-à-dire, celui de la tête, du cou, du dos, du croupion; les plumes des jambes du Lori à queue bleue, sont d’un rouge foncé, tirant au cramoisi. Toutes les couvertures des ailes sont du rouge cramoisi du corps, à l’exception de trois ou quatre de celles du millieu, qui sont bleu-foncé; queles autres de celles du millieu et les plus grandes sont lisérées de bleu. Les scapulaires, les deux dernières plumes des ailes près du dos, le bas-ventre et la queue entière, sont aussi bleus. Les grandes pennes alaires sont d’un noir brun. Le bec est d’un jaune d’ocre, et les pieds sont noirs.
L’espèce du Lori à queue bleue se trouve plus communément à l’île Bornéo. L’individu que nous en avons figuré de grandeur naturelle, fait partie de la belle collection de M. Raye de Breukelervaert, à Amsterdam.


The general plumage, that is to say, that of the head, neck, back, rump; the feathers of the blue-tailed Lori’s legs are dark red, scarlet-crimson. All the wing coverts are crimson red, with the exception of three or four of the middle ones, which are dark blue; the others from the middle and the larger ones are marked with blue. The scapulars, the last two feathers of the wings near the back, the lower abdomen and the whole tail, are also blue. The large wing tips are black-brown. The beak is ochre yellow, and the feet are black.
The Blue-tailed Lori is more commonly found on Borneo Island. The individual that we have figured in natural size, is part of the beautiful collection of Mr. Raye de Breukelervaert, from Amsterdam.“ [1]


What or who is this Blue-tailed Lori?

Well, if F. Le Vaillant did only see a dead, a stuffed bird, this may in fact just have been a Red Lory lacking its actual tail, which had been replaced by the blue tail of any other parrot species – this method was actually quite common in these days, either to complete a incomplete specimen or even to make a complete new species, a fake species if you want, something unique that could earn high prizes other collectors in search for something unique for their collection were often willing to pay.

There existed many such collections in the 18th and early 19th century, containing real natural treasures but also things like unicorn horns, dried mermaids, and, of course fake bird species, especially birds of paradise and parrots.

It is also interesting that the island of Borneo is given as the place of origin. The bird may very well have been bought on a bird market on that island to end up as a corpse in a collection in the Netherlands, but, being definetely a member of the genus Eos, it clearly was not native to that island.

My last words here: Levaillant’s Blue-tailed Lory very likely is just a Red Lory with a fake tail.

Unicolored Lory

The Unicolored Lory (Eos unicolor (Shaw)) is a bright red colored parrot, that is known from a single drawing and the annotated description in François Le Vaillant‘s ‚Histoire naturelle des perroquets‘ from the very early 19th century.

There were two individuals known at that time, kept in captivity in the Netherlands, from which one was depicted.:

L’uniformité de la coleur du plumage de ce Lori nous a déterminé à lui donner le surnom d’unicolore; et cette coleur est d’un rouge pâle sur la tête, le cou, la poitrine, l’estomac, le ventre et les couvertures du dessous de la queue. Le manteau et le croupion, les couvertures des ailes et celles de la queue, lla queue elle-même, sont aussi rouges, mais d‘un noir brun vers leur pointe. Le bec est rouge, et les pieds sont d‘un brun terreux.
L’espèce de ce Lori se trouve aux Moluques. M. Temminck, d’Amsterdam, qui avoit deux de ces oiseaux dans sa belle collection, eut la bonté de m’en donner un. Ces deux individus sont les seuls de l’espéce que j’aie jamais vus.


The uniformity of the color of the plumage of this Lori has determined us to give him the moniker nickname; and this color is pale red on the head, neck, chest, stomach, belly, and undertail coverts. The mantle and the rump, the coverts of the wings and those of the tail, the tail itself, are also red, but of a dark brown towards their point. The beak is red, and the feet are of an earthy brown.
The species of this Lori is found in Maluku. M. Temminck from Amsterdam, who had two of these birds in his fine collection, was kind enough to give me one. These two individuals are the only ones of the species I have ever seen.“ [1]


The Maluku Islands were a Dutch colony (at least in parts), so it’s no wonder that birds cought there were transported to Amsterdam.


Since the Unicolored Lory is now known exclusively from the single drawing in ‚Histoire naturelle des perroquets‘, some zoologists think that this depiction may in fact simply show a Cardinal Lory (Chalcopsitta cardinalis (G. R. Gray)) from the Solomon Islands. This species, however, is not that unicolored but has a bright red underside and a rather dull cherry-red upper side, a longer tail, as well as a patch of bare skin around its beak.

The drawings made by Jacques Barraband are not just only very good, they are in fact scientifically correct, even for modern standards, so the Unicolored Lory can indeed be identified as a member of the genus Eos. This genus contains at least six species, that all are confined to the islands in the Banda Sea (the Maluku Islands and some islands off western New Guinea), Indonesia. All of these species are mainly bright red colored, with more or less amounts of bright blue areas.

There is a slight possibility that the two birds kept in captivity, were of hybrid origin, but this leads to the question for the parent species, since all other known congeneric species bear at least some blue in their plumage, while the Unicolored Lory was completely red.

The Maluku Islands, especially the smaller islands, are heavily deforested and the original forest has been replaced by plantations, this has probably already begun in the 14th century, when the islands were discovered by Arab merchants. Most of the endemic lory species are now heavily threatened with extinction, and at least two taxa (the Red-and-blue Lory (Eos histrio ssp. histrio (Statius Müller)), and the Talaud Red-and-blue Lory (Eos histrio ssp. talautensis Meyer & Wiglesworth)) are already completely extinct.

The Unicolored Lory may have been restricted to a single, small island within the region, and its population may already have been very low due to deforestation and hunting, when the two individuals were caught and brought to the netherlands

There is no obvious reason why the Unicolored Lory should not have existed!
