Coban Baung is a location close to Mount Kawi, a dormant volcano in East Java. It isn’t too far-off from Kepanjen, the place I stayed the night time earlier than going there.
Probably the most attention-grabbing birds there may be the Ruby-throated Bulbul.
Sadly, like so many different hen species in Java, it’s threatened by trapping and thus categorized as Weak.
It’s virtually as typical that Cornell nonetheless has not up to date the profile web page of the Ruby-throated Bulbul accordingly, stating that the species is “Not globally threatened. Pretty widespread to widespread; uncommon in Bali. In most of vary nonetheless fairly widespread in drier forests of lowlands, regardless of heavy degradation; widespread even in japanese and southern Java”.
The scientific identify Rubigula dispar presumably signifies that the bulbul is completely different (“dispar”) from many different bulbuls.
In a examine performed in Java, Ashy Drongos had been discovered to play the function as leaders of combined flocks, main and defending the combined flock.
I’m not positive they will apply for maternity/paternity depart on this function when nesting.
The Black-naped Fruit Dove lives on Java and likewise within the Basel Zoo (Switzerland).
Although in fact, there it’s known as the Schwarzkappen-Fruchttaube. One way or the other, this identify makes me really feel the hen belongs to some right-wing Nazi celebration. Most likely not although.
In case you are extra occupied with schooling than in birds, and likewise communicate Indonesian, you would possibly wish to pay money for a paper titled “Abundance of Chook Species in Tadulako College Campus Space and its Utilization as a Studying Media”. After all, the species on the campus embrace our hero, the Black-naped Fruit Dove.
The “Systematics Historical past” part of the Cornell profile has the assertion “A particular type of unsure affinities”, which sounds reasonably complicated to me, or ought to I say it makes me really feel distinctively unsure?
As in people, the feminine seems completely different from the male.
For me, the 2 species of flowerpeckers had been a significant attraction of Coban Baung. First, the Crimson-breasted Flowerpecker.
Cornell describes the 56 species of flowerpeckers as “frenetic fruit-cruisers of tropical Asian forest canopies”.
Cornell additionally feedback on the identify of the household: “So far as we all know, they by no means really peck flowers, as a substitute consuming a weight loss program of fruit (particularly mistletoe) and nectar, which in addition they feed to their younger.”
Presumably, the percussus (“blood-stained”) within the scientific identify Prionochilus percussus refers back to the purple on the breast and likewise on the crown.
In case you are within the meals of this species, take a look at this put up (spoiler alert: it’s principally fruit, with just a few spiders combined in for protein).
Regardless of data comparable to this one, the Wikipedia entry on the genus Prionochilus ends with the standard assertion that’s routinely added to each analysis paper on the planet in a barely modified kind: “Details about the weight loss program (and plenty of different elements of the biology of this genus and certainly household) is patchy and extra analysis is required.”
Presumably, most flowerpecker specialists would agree that the identical applies to the Orange-bellied Flowerpecker, although it’s in one other genus (Dicaeum, which is by far the biggest genus of flowerpeckers).
The total scientific identify Dicaeum trigonostigma sounds vaguely Christian to me, but it surely actually simply signifies that the hen has a triangular mark on its again. It’s orange, and my photographs fail miserably to indicate it, apart from this one.
As with many flowerpeckers, the feminine is far much less engaging than the male, however specialists typically affirm that the females with out exception have a stupendous soul.
In keeping with Cornell, Orange-bellied Flowerpeckers take nectar from, and pollinate, a species of durian tree in Borneo – so, it’s fairly attainable they aren’t allowed to enter lodge rooms in Singapore.
The Javan Sunbird is a Javan endemic that has been cut up from Temminck’s Sunbird. To me, it seems very related, and I couldn’t discover any word on seen variations between the 2 species.
The mystacalis of the scientific identify Aethopyga mystacalis means “moustached”, however so is Temminck’s Sunbird (Aethopyga temminckii).
Equally, the Sangkar White-eye can also be the results of a cut up. Says Cornell: “A latest cut up from the previously giant wastebasket taxon Oriental White-eye, this small white-eye is now thought-about endemic to Java and Bali”.
The scientific identify Zosterops melanurus signifies that the hen has a black tail, which certainly appears to be a particular function. Then once more, with 111 species within the genus Zosterops alone, it most likely just isn’t.
Lastly, the Scarlet Minivet just isn’t the results of a cut up but – however the Cornell entry sounds ominous:
“Morphological and plumage analyses counsel races might symbolize 4 or 5 species, however exact boundaries unclear.”
