Black-headed Bulbul (Brachypodius atriceps)

The original is a photo by Mike Rose (, who kindly gave me the permission to use it. This is actually the first time a did a background with actual aquarell colors (watercolors), I’m not totally okay with the background, but the bird is quite fine!

Der Harlequinkolibri – eine Art die nie existiert hat … oder doch?

Diese heute wohl kaum mehr bekannte ‚Art‘ wurde im Jahr 1788 anhand eines einzelnen Exemplars sowie einer Beschreibung von John Latham [1] als Trochilus multicolor Gmelin beschrieben.

Der Harlequinkolibri erreichte laut Beschreibung eine Größe von insgesamt 12,7 cm, hatte einen relativ langen Schnabel und war recht auffällig gefärbt.

Es sind einige Abbildungen dieser ‚Art‘ überliefert, im Ganzen existieren allerdings eigentlich nur zwei verschiedene Darstellungen, die wieder und wieder von verschiedenen Künstlern kopiert wurden. [2]

Wunderschön, aber ursprünglich wohl trotzdem eine aus verschiedenen Vögeln zusammengebaute Fälschung

Das einzige bekannte Harlequinkolibri-Exemplar wurde 1819 (?) als Fälschung erkannt und letzlich weggeworfen, so dass es nicht mehr für weitere Untersuchungen zur Verfügung steht. [2]

Neu beschrieben – Cremeaugenbülbül

Cremeaugenbülbül (Pycnonotus pseudosimplex Shakya et al.)

Diese Art wurde gerade erst beschrieben, es handelt sich um eine der vielen kryptischen Arten, die bis dahin übersehen wurden.

Die Art ist offenbar näher mit dem Graustirnbülbül (Pycnonotus cinereifrons (Tweeddale)) von der Insel Palawan, Philippinen verwandt als mit dem Weißaugenbülbül (Pycnonotus simplex Lesson), mit dem er seinen Lebensraum auf der indonesischen Insel Borneo teilt und dem er stark ähnelt. [1]

Pumiliornis tessellatus Mayr

Pumiliornis means as much as “dwarf bird”, and with that, all has been said.


No, not so fast ….

The genus/species was described in 1999 and is, to my knowledge, so far known from three skeletal finds, of which one even contains the remains of its last meal, namely pollen.

All in all, Pumiliornis tessellatus resembled today’s sunbirds (Nectariniidae) or the sunbird-asitys (Eurylaimidae) in being very small and having an elongated beak. Its beak, however, was quite unlike those of the members of the beforementioned two families, it resembled the beak of a plover (Charadriidae), especially its narial opening (nose hole), which was rather slit-like and not round.

Pumiliornis was apparently a flower-visitor that fed on nectar and pollen (as is known from the content of the gut of one specimen), however, it may not have been specialized to that diet and may also have taken insects and other small invertebrates.

The bird was small, very small, in my reconstruction it reaches a length of only 7,5 cm, this size, however, is of course depending on the length of its tail feathers, which unfortunately are not preserved in any of the known specimens. I’ve reconstructed the bird with a rather short tail, which may some day turn out to be completely wrong, who knows.

The feet corresponded to the typical scheme of recent passerine birds, i.e. they have three toes pointed forward and one towards the back. However, the feet appear to have been facultative or semi-zygodactyl, which in turn means, in simple terms, the first toe usually pointed forwards, but could be held backward when needed.


The genus/species cannot be assigned to any living bird family, not even an order, but is now known to belong to the extended Passeriformes-orbit, which in addition to the passerine birds also includes the falcons (Falconiformes) and the parrots (Psittaciformes). In fact it is now known to have been a member of the extinct family Psittacopedidae, that apparently also contains other unusual genera like MorsoravisPsittacopes and the recently described, very interesting Eofringillirostrum and probably others too.


Finally, it should be mentioned that this bird was not a dwarf spoonbill, as claimed by a certain person.   😉

Eleven steps to draw a bird

Hi there!

It’s coffee/tea time, whatever you prefer … and it’s dark outside, and thus it’s dark inside too.  


I have decided to make another >step by step<, or >how to do<, or whatever you may call it series, of how I draw a bird, this time it is another extinct one, yet only known from two of its bones, so the coloration is just imagined.  


1: a sketch is made

2: the sketch is fixed with the pencil 

3: the sketch is finished, the surroundings are included

4: the rubber color is put on the bird

5: the rubber color has dried, the background is created with water color and a sponge

6: the background has dried, the rubber color is rubbed away

7: the actual coloring begins, I use my loved watercolor pencils

8/9: the watercolor is blurred with a brush and with water

10: the water has dried, the details are now worked out using the watercolor pencils again

11: the most important step, probably; the last details are worked out with a pencil, and the white dot is placed inside the eye 

The end result is a drawing of a Cuban Tapaculo (Scytalopus sp.)
