Birding Sepilok, Borneo (Section 1)


Sepilok is among the very best puts I ever frolicked birding at – I did so for per week and will have simply spent extra time there. So, to be able to economize somewhat, the Sepilok birds are described in 3 separate posts.

The Ashy Tailorbird is a great instance of the other views of describing a hen – whilst the English identify specializes in the frame of the hen, the Latin species identify ruficeps refers back to the rufous head.

Birding Sepilok, Borneo (Section 1)

Whilst those pictures are non violent sufficient, a paper at the predation of an Ashy Tailorbird by means of a paradise gliding snake has extra dramatic illustrations. Viewer discretion is suggested, specifically in case you have a look at the paper within the corporate of Ashy Tailorbird chicks.

Against this, a paper at the foraging conduct of 2 tailorbird species (together with the Ashy Tailorbird) makes for a extra non violent studying, which is a well mannered approach of claiming that I discovered it reasonably dull. I suppose the gratuitous violence within the different paper is extra interesting.

It seems that, there are 12 species of babblers at Sepilok – I best noticed 3 of them, partially because of their traits (they typically keep on the subject of the bottom and like colours corresponding to grey, brown, or black to these colours reputedly worn by means of beginner cyclists these days [which I take as proof for my theory that most of these cyclists must be color blind]) and partially as a result of It’s not that i am an excellent birder. (I simply re-read the remaining sentence, discovered it somewhat complicated however sooner or later made up our minds to depart it unchanged – in the end, it’s you who has to learn it, now not me).

Anyway, some of the babblers of Sepilok is the Bornean Black-capped Babbler – the results of a break up of the Black-capped Babbler (neatly, no less than from a human point of view – the birds themselves are most definitely moderately nonchalant about it). Because the break up best took place in 2021, it’s going to most definitely take no less than 5 extra years for the web model of the HBW to create a separate species web page for this babbler. Perhaps the HBW will have to be administered by means of a school with a more potent pastime in birds than Cornell.

The break up makes the hen some of the six species endemic to Sabah, Borneo (supply), 4 of which I noticed all the way through my week at Sepilok.

The Brief-tailed Babbler is assessed as Close to Threatened. eBird highlights its “virtually nonexistent stump for a tail” however then the author of this description perhaps has no tail in any respect.

 

I were given alongside slightly neatly with the Brief-tailed Babblers at Sepilok as in step with eBird, they’re “now not as social as different woodland babblers”. So we agreed that I simply take a couple of pictures of them, then we went our separate tactics, none of the standard spherical of beverages after a photograph capturing that appears to be virtually obligatory when coping with maximum different babbler species.

Probably the most fascinating function of the Chestnut-winged Babbler is the presence of blue pores and skin patches (regardless that I’m afraid that my pictures don’t totally do them justice). A paper discusses the serve as of those patches, hypothesizing that “blue facial pores and skin purposes as a visible sign in sexual conversation for a variety of species, most likely as a trademark of health”. Perhaps this may be the place the colourful garments of the cyclists have their beginning?

The paper cites the instance of the Blue-footed Booby: Its foot colour turns into duller when the birds are malnourished. If the male’s colour fades after the primary egg, the feminine reacts by means of laying a smaller 2d egg – reputedly deciding that it’s higher to chop her losses because the male it appears is the avian similar of a deadbeat father.

The Chestnut-winged Babbler is referred to as some of the host species of the Asian Drongo-cuckoo in Southeast Asia (supply), a declare to status that the majority hen species would most definitely wish to steer clear of. However perhaps mentioning a cuckoo brings excellent karma, who is aware of …

After the preliminary posting, Andrew Bailey knowledgeable me that once a break up, the babbler above is now Gray-hooded Babbler. My excuses are that the 2 species appearance very identical, and that It’s not that i am a excellent birder.

The 2 most simply noticed pittas of Sepilok have been already mentioned in an previous submit – the Hooded Pitta

… and the Black-crowned Pitta (some other Sabah endemic).

Whilst monarchies and monarchs will have to be abolished in all places on the planet (word to the Economist: have some ideas on this topic, some spine!), the Black-naped Monarch will have to now not.

However then, the Black-naped Monarch hasn’t ever claimed to reign by means of divine proper, nor has it ever been accountable for large-scale wars, slavery, colonialism, and so on. (one thing that the enthusiasts of constitutional monarchies appear to disregard, focusing as an alternative at the heat and fuzzy feeling of getting a monarch as a type of ersatz father).

Knowing that during writing about this I’m speaking (or moderately writing) myself in a heartfelt however probably very dull and self-righteous nook, let’s get again to the deficient hen species which isn’t at fault for being known as a monarch. eBird talks of the “stunning azure-blue male”, which my pictures won’t totally seize. On the similar time – and perhaps as repayment for the reward showered at the hen’s look – the music is described as “a bland, unremarkable ‘wi-wi-wi-wi-wi-wi-wi.’” 

My center sinks somewhat when I’m in search of fascinating data on a hen species to move together with my pictures, and the one articles I will in finding are both at the mitochondrial genome of the species (sure, we get it! Sure, you’ll get that data! More than likely with no need a unmarried idea whilst doing it! And you’ll nonetheless get a paper out of it! You’ll be able to even upload 3 or 4 of your folks as coauthors – as actually no one is aware of how a lot paintings this sort of paper is anyway – and hope they may go back the prefer later) or a paper with a identify like “composition of blended species flocks” or ” survey of avian inhabitants at xy” (those papers are actually simply eBird lists became papers) or papers like “first incidence of hen species xy at location z”. Sadly, it sort of feels that the Black-winged Flycatcher-shrike is this sort of hen.

The species identify hirundinaceus is somewhat unusual – it method “swallow-like”, which in the case of colour might in fact make some sense however with the exception of that, this isn’t a hen corresponding to a swallow.

 

The Bornean Black Magpie lacks the white stripes (additionally a band identify: White Stripes, see right here) of the (Malaysian) Black Magpie and is now known as a separate species. It’s endemic to Borneo.

Within the medical literature, the Bornean Black Magpie best makes an excessively transient cameo look – a paper describes a brand new genus of chewing lice discovered at the museum specimen of this hen. Why somebody would read about a specimen accrued in 1888 for mummified chewing lice is a thriller to me, however so is the attraction of Donald Trump.

I used to be anticipating to look moderately a couple of barbets in Sabah however sooner or later best were given first rate pictures of 1, the Brown Barbet. Thankfully, barbets are slightly not unusual in Yunnan, China, so it used to be now not a selected unhappiness. Actually, this can be a moderately fascinating barbet, meriting the eBird description as a “distinctive, strange-looking barbet with a large invoice and vivid pink legs”.

Given the colour of the invoice (brown, now not black), this will have to be a feminine.

I didn’t discover a unmarried paper in particular protecting this species – only some informal mentions in papers with titles corresponding to “Elevational distribution patterns of understorey woodland hen in Western Sarawak, Malaysian Borneo”. Perhaps one of the most guys spending such a lot time on mitochondrial genomes may just challenge out in their labs and perform a little fieldwork …

The Java Myna appears to be spreading, probably crowding out any other myna species such because the …

 

Not unusual Hill Myna.

It seems that, the Better Coucal is related to some superstitions – in India, seeing one is assumed to be auspicious, and in some spaces, consuming the flesh used to be looked to lend a hand with sicknesses corresponding to tuberculosis.

In imperial British India, inexperienced persons to India frequently mistook the coucal for a pheasant and shot it, best to be upset, calling it “evil flavored” later. I feel they only were given what they deserved.

And naturally, some Chinese language researchers labored at the whole mitochondrial genome of the Better Coucal. Are those the paper generators one once in a while reads about relating to Chinese language analysis papers?

A slightly difficult to understand paper stories at the Better Coucal feeding on a Not unusual Myna chick. Now, that’s what we actually need to examine! (“Das ist die Artwork von Gewalt, die wir sehen wollen. Wenn wir auch nichts spueren wollen”, ‘Los Paul‘, Das Trio).

Sepilok is a great position to look a variety of woodpecker species. As amongst experts, this is a cardinal rule to at all times observe some roughly ordering concept, listed below are 5 Sepilok woodpeckers so as of dimension, ranging from the smallest one. This dimension comparability will mean you can simply choose the species that very best serves your whole woodpecker wishes.

The smallest on be offering is the Rufous Piculet (8-9.5 cm).

It’s obviously your best option in case you like your woodpeckers small – eBird explicitly calls it an “completely miniscule woodpecker”

Its medical species identify is abnormis, and certainly it’s odd some of the woodpeckers (regardless that it stocks this with any other piculets). Actually, John MacKinnon (of “Information to the Birds of China”) in a up to date Shanghai presentation known as it “now not an actual woodpecker in any respect”, and whilst he’s fallacious about that, I kind of see his level.

Because the expenses of piculets are shorter and no more dagger-like than the ones of the opposite woodpeckers, they re-use woodpecker holes for nesting, moderately than making their very own holes. Makes them kind of the renters of the woodpecker global moderately than house owners.

If the piculet is just a bit bit too small for you, why now not opt for the Gray-and-buff Woodpecker (13.5 cm)?

Don’t let the medical identify concretus (wide, robust, robust) idiot you – it’s certainly a small woodpecker, but it surely already fulfills lots of the wishes of moderate woodpecker shoppers.

It seems that, this woodpecker has a slightly odd roosting conduct, with strong teams of 3 and 4 woodpeckers roosting for my part in within reach cavities, with many extra cavities on the roosting website than woodpeckers. This permits the person birds to modify cavities each night time, they usually like this added selection such a lot that the grownup men are even incessantly operating at the excavation of extra cavities (supply).

In client merchandise, now and again small sizes are best on be offering to make the buyer really feel higher about going for one thing larger. If so, perhaps the Banded Woodpecker (23-26 cm) is the appropriate selection as it’s proper in the course of the Sepilok woodpecker portfolio and thus an excessively cast selection for middle-class woodpecker customers.

The species it appears tries to get extra such customers – a systematic paper states that “The Banded Woodpecker (Chrysophlegma miniaceum malaccense) has a ‘classical’ promoting name”.

Then again, eBird nonetheless regards this woodpecker as small, regardless that with a fantastic look (“small however brightly-colored woodpecker with a spiky crest”).

So perhaps that dimension isn’t sufficient, and you wish to have one thing just a bit bit larger, such because the Orange-backed Woodpecker (30 cm)? This species elevates you from the ones simply in quest of a mean woodpecker to people who call for somewhat extra from their avian possible choices.

Pleasingly for the ones choosing this woodpecker, one web site already calls it a “slightly wide woodpecker” – regardless that to be honest, the HBW calls it “medium-sized”. So, it will simply be the appropriate selection for discerning woodpecker customers who on the similar time need to steer clear of any trace of being flashy.

In any case, in case you already power a Porsche and need the neighbors to envy you even within the woodpecker realm, the White-bellied Woodpecker (40-48 cm) is the appropriate one for you. Make your neighbors envy you much more once they learn within the HBW that this can be a “wide to large woodpecker”!

Granted, if you select this woodpecker, your neighbors might also call to mind you as somewhat of a show-off. However in case you already power a Porsche, this will have to now not actually trouble you.

And you’ll sleep within the secure wisdom that until your neighbors get both a Black Woodpecker or a Nice Slaty Woodpecker, yours will indisputably be the largest in the community. For some males, such issues could also be essential.

A last benefit of this woodpecker is that with 14 or 15 subspecies (relying on supply), it provides a variety of choices to compare your actual woodpecker necessities. And it additionally comes as a video and but some other video.

And now for one thing utterly other. The pretty Pink-bearded Bee-eater differs from maximum different bee-eaters in that it isn’t a colonial breeder however moderately nests solitary or in pairs (supply).

Thus on this case the species identify amictus is smart, as this implies unsociable. It additionally method I’ve discovered some other soulmate within the avian global.

The male and the feminine Pink-bearded Bee-eater appearance reasonably other – the lilac crown of the male extends additional and is greater. So, what you notice here’s a feminine.

This bee-eater is some other hen species with a slightly underwhelming paintings ethic. A paper states that “Nyctyornis bee-eaters are slow all the way through foraging, spending lengthy sessions of time on a look-out perch within the center to higher cover stage and flying down to select up arthropod prey when noticed”. 

That paper additionally has some great pictures of the Pink-bearded Bee-eater on the front of its nest burrow, feeding its chicks.

The Blue-throated Bee-eater is way smaller than its relative, and more uncomplicated to look because it likes to seek from open wires moderately than throughout the woodland.

Whilst about 72% of its chicks are sired by means of the nominal oldsters, about 7% are the results of intra-specific nest parasitism (i.e., an unrelated feminine dumps an egg right into a nest), 7-12 % are the offspring of the paired male and an extra-pair feminine, and no more than 5% are the offspring of the paired feminine and an extra-pair male (supply).

Nonetheless, the 28% of chicks now not associated with each oldsters could also be some of the causes for the somewhat prime stage of infanticide some of the chicks (eggs now not laid by means of the paired feminine are much more likely to be added at a later degree of the egglaying, as the feminine ejects all eggs put into the nest ahead of she begins laying eggs herself). Thus the infanticide seen could also be a protecting measure to scale back intra-specific brood parasitism, specifically when the meals provide is tight (supply).

At Sepilok, it may be exhausting to steer clear of taking pictures of a few non-birds, corresponding to primates. As you understand, some primates face a variety of court docket circumstances, each felony and civil ones. Thankfully, those at Sepilok don’t have those problems and appearance marginally extra horny as neatly.
