Birding Sepilok, Borneo (Section 1) – 10,000 Birds


Sepilok is among the perfect puts I ever hung out birding at – I did so for every week and will have simply spent extra time there. So, to be able to economize a little, the Sepilok birds are described in 3 separate posts.

The Ashy Tailorbird is a superb instance of the other views of describing a hen – whilst the English title makes a speciality of the frame of the hen, the Latin species title ruficeps refers back to the rufous head.

Whilst those footage are non violent sufficient, a paper at the predation of an Ashy Tailorbird through a paradise gliding snake has extra dramatic illustrations. Viewer discretion is suggested, specifically for those who take a look at the paper within the corporate of Ashy Tailorbird chicks.

By contrast, 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 manner of claiming that I discovered it rather uninteresting. 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, in part because of their traits (they generally keep just about the bottom and like colours reminiscent of grey, brown, or black to these colours reputedly worn through novice cyclists lately [which I take as proof for my theory that most of these cyclists must be color blind]) and in part as a result of I’m really not an excellent birder. (I simply re-read the remaining sentence, discovered it a little complicated however ultimately determined to go away it unchanged – in spite of everything, it’s you who has to learn it, no longer me).

Anyway, some of the babblers of Sepilok is the Bornean Black-capped Babbler – the results of a cut 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 cut up best came about 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. Possibly the HBW must be administered through a school with a more potent pastime in birds than Cornell.

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

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

 

I were given alongside somewhat neatly with the Brief-tailed Babblers at Sepilok as in keeping with eBird, they’re “no longer as social as different wooded area babblers”. So we agreed that I simply take a couple of footage of them, then we went our separate tactics, none of the standard spherical of beverages after a photograph taking pictures that appears to be nearly obligatory when coping with maximum different babbler species.

Essentially the most attention-grabbing function of the Chestnut-winged Babbler is the presence of blue pores and skin patches (even though I’m afraid that my footage don’t absolutely 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 quite a lot of species, perhaps as a trademark of health”. Possibly this could also be the place the colourful garments of the cyclists have their starting place?

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 through laying a smaller 2d egg – reputedly deciding that it’s higher to chop her losses because the male it appears is the avian identical 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 reputation that the majority hen species would most definitely like to keep away from. However possibly mentioning a cuckoo brings excellent karma, who is aware of …

The 2 most simply observed pittas of Sepilok had been already mentioned in an previous publish – the Hooded Pitta

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

Whilst monarchies and monarchs must be abolished far and wide on this planet (notice to the Economist: have some rules on this subject, some spine!), the Black-naped Monarch must no longer.

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

Figuring out that during writing about this I’m speaking (or moderately writing) myself in a heartfelt however possibly very uninteresting and self-righteous nook, let’s get again to the deficient hen species which isn’t at fault for being referred to as a monarch. eBird talks of the “gorgeous azure-blue male”, which my footage would possibly not absolutely seize. On the similar time – and possibly as reimbursement 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 a little when I’m on the lookout for attention-grabbing knowledge on a hen species to go together with my footage, and the one articles I will be able to in finding are both at the mitochondrial genome of the species (sure, we get it! Sure, you’ll be able to get that knowledge! Most certainly with no need a unmarried concept whilst doing it! And you’ll be able to nonetheless get a paper out of it! You’ll be able to even upload 3 or 4 of your folks as coauthors – as truly no person is aware of how a lot paintings any such paper is anyway – and hope they could go back the desire later) or a paper with a name like “composition of combined species flocks” or ” survey of avian inhabitants at xy” (those papers are truly simply eBird lists changed into papers) or papers like “first prevalence of hen species xy at location z”. Sadly, it sort of feels that the Black-winged Flycatcher-shrike is any such hen.

The species title hirundinaceus is a little unusual – it method “swallow-like”, which when it comes to colour would possibly in fact make some sense however aside from that, this isn’t a hen comparable to a swallow.

 

The Bornean Black Magpie lacks the white stripes (additionally a band title: 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 temporary 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 enchantment of Donald Trump.

I used to be anticipating to look moderately a couple of barbets in Sabah however ultimately best were given respectable footage of 1, the Brown Barbet. Thankfully, barbets are somewhat not unusual in Yunnan, China, so it used to be no longer a selected sadness. In reality, this can be a moderately attention-grabbing barbet, meriting the eBird description as a “distinctive, strange-looking barbet with an enormous invoice and vivid purple legs”.

Given the colour of the invoice (brown, no longer black), this must be a feminine.

I didn’t discover a unmarried paper particularly overlaying this species – only a few informal mentions in papers with titles reminiscent of “Elevational distribution patterns of understorey wooded area hen in Western Sarawak, Malaysian Borneo”. Possibly probably the most guys spending such a lot time on mitochondrial genomes may just undertaking out in their labs and do a little fieldwork …

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

 

Commonplace Hill Myna.

It seems that, the Higher Coucal is related to some superstitions – in India, seeing one is thought to be auspicious, and in some spaces, consuming the flesh used to be looked to lend a hand with diseases reminiscent of tuberculosis.

In imperial British India, freshmen to India incessantly mistook the coucal for a pheasant and shot it, best to be disillusioned, calling it “evil flavored” later. I believe they only were given what they deserved.

And naturally, some Chinese language researchers labored at the entire mitochondrial genome of the Higher Coucal. Are those the paper turbines one once in a while reads about when it comes to Chinese language analysis papers?

A somewhat difficult to understand paper studies at the Higher Coucal feeding on a Commonplace Myna chick. Now, that’s what we truly 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 superb position to look quite a lot of woodpecker species. As amongst specialists, this can be a cardinal rule to all the time observe some more or less ordering theory, listed here are 5 Sepilok woodpeckers so as of dimension, ranging from the smallest one. This dimension comparability will can help you simply make a selection the species that perfect serves your whole woodpecker wishes.

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

It’s obviously your best option for those who like your woodpeckers small – eBird explicitly calls it an “completely miniscule woodpecker”

Its medical species title is abnormis, and certainly it’s odd a number of the woodpeckers (even though it stocks this with another piculets). In reality, John MacKinnon (of “Information to the Birds of China”) in a contemporary Shanghai presentation referred to as it “no longer 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 international moderately than house owners.

If the piculet is just a bit bit too small for you, why no longer opt for the Gray-and-buff Woodpecker (13.5 cm)?

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

It seems that, this woodpecker has a reasonably odd roosting conduct, with solid teams of 3 and 4 woodpeckers roosting in my opinion in within reach cavities, with many extra cavities on the roosting web page than woodpeckers. This permits the person birds to modify cavities each evening, they usually like this added selection such a lot that the grownup men are even ceaselessly operating at the excavation of extra cavities (supply).

In client merchandise, infrequently small sizes are best on be offering to make the client really feel higher about going for one thing larger. If so, possibly the Banded Woodpecker (23-26 cm) is the fitting selection as it’s proper in the midst of the Sepilok woodpecker portfolio and thus an excessively forged 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, even though with an exquisite look (“small however brightly-colored woodpecker with a spiky crest”).

So possibly that dimension isn’t sufficient, and you need one thing just a bit bit larger, such because the Orange-backed Woodpecker (30 cm)? This species elevates you from the ones simply in search of a median woodpecker to people who call for a little extra from their avian alternatives.

Pleasingly for the ones choosing this woodpecker, one web site already calls it a “somewhat wide woodpecker” – even though to be truthful, the HBW calls it “medium-sized”. So, it will simply be the fitting selection for discerning woodpecker customers who on the similar time need to keep away from any trace of being flashy.

In spite of everything, for those who 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 fitting 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 bring to mind you as a little of a show-off. However for those who already power a Porsche, this must no longer truly hassle you.

And you’ll be able to sleep within the protected wisdom that except your neighbors get both a Black Woodpecker or a Nice Slaty Woodpecker, yours will without a doubt be the most important locally. For some males, such issues could also be necessary.

A last benefit of this woodpecker is that with 14 or 15 subspecies (relying on supply), it gives plenty 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 totally other. The pretty Crimson-bearded Bee-eater differs from maximum different bee-eaters in that it’s not a colonial breeder however moderately nests solitary or in pairs (supply).

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

The male and the feminine Crimson-bearded Bee-eater appearance rather other – the lilac crown of the male extends additional and is larger. So, what you spot here’s a feminine.

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

That paper additionally has some great footage of the Crimson-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 within the wooded area.

Whilst about 72% of its chicks are sired through the nominal folks, 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 feminine (supply).

Nonetheless, the 28% of chicks no longer associated with each folks could also be some of the causes for the reasonably top degree of infanticide a number of the chicks (eggs no longer laid through the paired feminine are much more likely to be added at a later level of the egglaying, as the feminine ejects all eggs put into the nest earlier than she begins laying eggs herself). Thus the infanticide seen could also be a protecting measure to cut back intra-specific brood parasitism, specifically when the meals provide is tight (supply).

At Sepilok, it may be exhausting to keep away from taking footage of a few non-birds, reminiscent of primates. As you recognize, some primates face quite a lot of courtroom circumstances, each prison and civil ones. Thankfully, those at Sepilok shouldn’t have those problems and appearance marginally extra sexy as neatly.
