Birding Shanghai in November 2022 – 10,000 Birds


November in Shanghai means the large-scale return of buntings, such because the smallest of them, the appropriately named Little Bunting.

 

Nevertheless, the most typical bunting at Nanhui in winter is the Pallas’s Reed Bunting. Curiously, eBird states that the “tune is a collection of moist buzzy ‘tsli’ notes”. What are moist notes?

 

Since 2016, the Rustic Bunting has been listed as Weak, as knowledge recommended speedy inhabitants declines (HBW). led its itemizing as Weak. Certainly, some papers have somewhat gloomy titles, equivalent to “The subsequent widespread and widespread bunting to go? World inhabitants decline within the Rustic Bunting Emberiza rustica“.

 

The migration patterns of Yellow-throated Buntings have been analyzed through a somewhat intelligent but considerably difficult methodology, isotope-based geographic task. Given the complexity of the analysis, the consequence seems like a little bit of a letdown – “northern populations begin migration sooner than southern populations, particularly in autumn”.

 

 

The species title of the Chestnut-eared Bunting is fucata, from the Latin “fucare”, to color crimson.

I didn’t discover a lot about this chicken on-line apart from a paper with the thrilling title “A brand new quill mite Torotrogla emberizae sp. nov. (Acariformes: Syringophilidae) from the Chestnut-eared Bunting (Passeriformes: Emberizidae) in Japan (morphology and DNA barcode knowledge)”. Ah, to be a scientist.

Hopefully, the winter time in Shanghai provides the Black-faced Buntings a while to calm down from the challenges of the breeding season. A problem for the males is getting cuckolded by members of the identical species – which required strenuous mate-guarding (supply). In distinction, the females want to verify to not get duped into elevating precise cuckoos – the buntings are a focused host species (supply). Thankfully for the buntings, they appear to detect most cuckoo eggs smuggled in (75% in a single research).

 

It appears that evidently the protection mechanisms towards parasitism by cuckoos might differ inside a species, relying on the dimensions of the menace posed by cuckoos. A research discovered that for Plain Prinia, egg traits in a mainland China location with many cuckoos make it a lot simpler to identify cuckoo eggs than in a Taiwan location with few cuckoos (supply). For individuals who suppose evolution is a improper principle, these variations might effectively have been created by god.

 

The Chestnut-crowned Warbler may be very uncommon at Nanhui – actually, it’s the first one I’ve seen right here in Shanghai. Elsewhere, it’s common sufficient to even be parasitized by cuckoos – which has made them begin to reject eggs based mostly on dimension (supply).

 

Provided that this chicken strikes very quick and thus results in chicken photographers spending loads of time getting principally utterly unusable images, I believe the parasitism is well-deserved. Possibly there may be some justice on this world in spite of everything.

 

Bramblings in Finland – although not really being parasitized by cuckoos – nonetheless rejected the overwhelming majority of non-matching eggs in a research – they thus appear well-prepared for a possible future cuckoo invasion. Higher secure than sorry.

 

I’ll have mentioned this earlier than, however thrushes at all times remind me a little bit of German housewives – sturdy and dependable, however not significantly sleek (there’s a motive I dwell in China and never in Germany). This definitely applies to the comparatively featureless Pale Thrush, which principally lives as much as its unpromising title somewhat effectively.

This thrush really is among the many prey gadgets of the very uncommon Iriomote Cat, a cat that lives solely on a small island. As it’s critically endangered (there are solely about 100 left), I believe it may be forgiven for killing the occasional Pale Thrush (which is listed as Least Concern).

The White-browed Thrush isn’t much more engaging. As a consequence, it solely performs a really small cameo position in a paper on the time required for species detection through digicam traps.

And what are you able to count on of a species named Dusky Thrush? Really, it appears to be like a bit extra fascinating than the title suggests, I believe.

Alternatively, it will get some factors deducted for trying too just like Naumann’s Thrush. The chicken is known as after Johann Andreas Naumann (1744-1826), a farmer and novice naturalist who – regardless of being a German – apparently didn’t commit any noteworthy atrocities.

Admittedly, the male Japanese Thrush doesn’t fairly match into the thrush sample as it’s fairly engaging. One Japanese research discovered that it arrives at its breeding grounds sooner than prior to now, probably attributable to elevated spring temperatures. Why these have occurred, no one is aware of – it can’t be attributable to world warming as Donald Trump in 2012 has made clear that local weather change was “created by and for the Chinese language so as to make US manufacturing non-competitive” (supply).

 

 

The feminine isn’t fairly as engaging however nonetheless simply beats most German housewives.

 

Given the experience of Mr. Trump, the Chinese language should even be chargeable for the sooner laying date of Northern Lapwings, as described right here.

Unusually, the Latin title of the Hair-crested Drongo is Dicrurus hottentottus – Hottentot is a reputation beforehand given to the Khoikhoi, a nomad pastoral individuals of Namibia and South Africa, distant from the place this drongo lives. The title Hottentot is best not used attributable to its unfavourable connotations: “The primary Dutch to come across the San and Khoikhoi peoples referred to them as ‘Hottentots,’ or stutterers, as a result of their Khoisan language employs clicks to indicate consonants, a characteristic of speech unsympathetic to European ears.  Thus, the disparaging time period “Hottentot” grew to become an ordinary identifier of the inhabitants of southwest Africa” (supply). Thus, the poor drongo is contributing to the perpetuation of racism …

Do the male Hair-crested Drongos search to have intercourse with females apart from their fastened accomplice (they’re socially monogamous)? Sure, however provided that there are sufficient females round, finds a research. Hm.

As with many different chicken species, the Latin title of the Hen Harrier, cyaneus (“darkish blue”), isn’t an excellent description of the feminine.

Sadly, Hen Harriers die disproportionally close to British Grouse moors – probably killed illegally by individuals searching grouse for sports activities (supply). I believed the British see themselves as very reasonable sportspeople – that is undoubtedly not a great instance. I want there was a method to give some weapons to Hen Harriers in order that they might shoot again.

In response to this paper, “Feeding by Black-faced Spoonbills usually seemed chaotic as a result of they normally stroll all around the feeding website at a variable velocity”. You possibly can see for your self right here.

 

And sure, they’re combined with Eurasian Spoonbills. If you’re a frog and need to learn a horror story, you could need to try this paper. Wherein a largish marsh frog – resisting being swallowed by a Eurasian Spoonbill by spreading its limbs – will get them damaged one after the other till resistance is futile and the frog will get swallowed after 10 minutes. Guantanamo for frogs. Although to be traditionally correct, the breaking wheel could be a greater comparability. Then once more, what the spoonbill does additionally has its waterboarding element: “[The bird] shook the marsh frog underneath the water to interrupt the limbs one after the other”.

 

Amongst philosophically-minded Dunlins, the dichotomy between being a person …

… and being half of a giant society is extensively mentioned.

In an evaluation of birds offered at Indonesian chicken markets, the Scaly-breasted Munia was discovered to be by far probably the most quite a few species, accounting for greater than half of all people. Weirdly, this chicken can be described as a standard pest in Indonesia, chargeable for substantial losses of rice. Alternatively, within the West, mice, and rats are additionally saved as pets, perhaps with the identical logic.

The Pallas’s Leaf Warbler shares its title with not less than 6 different chicken species together with the bunting proven above – a little bit of an overkill when you ask me. Alternatively, he bought his Ph.D. when he was 19 whereas it took me 10 years extra. No marvel no species are named after me.

 

It appears that evidently Black-tailed Godwits are a bit extra individualistic than many different species. A research discovered that they arrive at their breeding grounds throughout a span of greater than 5 weeks – considerably bigger than for many different birds. Presumably, the late arrivals then mate with different late arrivals, additional saying the variations and finally main to 2 subspecies, Black-tailed Godwit rapidus and Black-tailed Godwit tardus (sure, I studied Latin in highschool and am joyful to indicate off about this).

I don’t have something fascinating to say in regards to the Purple-flanked Bluetail proper now, however the male is a really lovely chicken.

 

A research on the breeding success of the Gray Heron had one very predictable consequence (“chick mortality considerably decreased with rising numbers of feeding visits per nest”) and one barely horrifying one (“siblicide was additionally a vital motive of chick mortality in these colonies – 54% and 32% chicks died in nests the place sibling aggression was noticed”). So assuming that these outcomes are transferable to people, mother and father ought to feed their offspring usually (first discovering) however limit themselves to at least one youngster (second discovering).

 

Presumably a survivor of siblicide (which might make it a killer, proper?)

In a paper on the Oriental Turtle Dove, Toshio Okazaki and Shinichiro make the daring declare that the “research represents the primary demonstration of protoporphyrin IX in dove plumage”.

 

It appears Black-winged Stilts have a desire for utilizing one or the opposite eye relying on the exercise (“behavioral lateralization”, to sound like an actual scientist). They’re extra profitable catching meals when trying with their proper eye however the males desire to take a look at the females with their left eye. If that isn’t proof of an almighty creator god, then what’s?

 

eBird calls the Black-winged Stilt a “placing giant black-and-white wader with a skinny, straight invoice and shiny pink legs” – a mistake, as my photograph reveals the chicken clearly solely has one leg.

My guess is that (just like some actors who didn’t efficiently make the transition from silent motion pictures to talkies), Pied Kingfishers have been extra in style with chicken photographers earlier than coloration images grew to become extensively used. It’s the solely kingfisher with none coloration apart from black and white (the male Crested Kingfisher has some rufous bits on its breast).

 

As this video signifies, these birds spend loads of time not doing a lot – or in scientific phrases, “resting/perching”. This was present in a research – do you need to guess the place this research was accomplished? A slight trace – the title of the research is “Exercise patterns of pied kingfisher (Ceryle rudis) and stork-billed kingfisher (Pelargopsis capensis) on the Chittagong college campus, Bangladesh” …

Chinese language Penduline Tits apparently bury their eggs inside their nests to stop them from falling out of the nests on windy days. The plain different resolution – constructing sturdier nests constituted of concrete strengthened with metal, as any first rate human would suggest – doesn’t appear to cross their minds.

 

Black-crowned Evening Herons (not less than the adults) appear to benefit from the autumn colours, as they properly complement their very own look.

 

The juveniles look depressing as common.

 

The sector identification part of the HBW entry for the Chinese language Gray Shrike has a a lot nicer photograph than this one, taken by me 5 years in the past. Nicely, I assume I used to be a greater photographer then.

Eurasian Woodcocks are normally a lot better hidden than proven in my latest put up. A typical daytime encounter might seem like this:

And I’m positive that if this put up had been written by Dave Barry, he would comment that Eurasian Woodcocks could be an ideal title for a punk band.

The HBW entry for the Mallard has a 300-word part on priorities for future analysis solely – sort of puzzling provided that that is definitely a well-researched species. However then, perhaps not – it appears to be the character of science that the extra , the extra you need to know. A lot for this put up’s pseudo-philosophical thought.

The courtship of the Higher Scaup sounds a bit horrifying to me: “Throughout courtship, males collect in teams of as much as 17 and encompass a single feminine whereas calling” (supply). Alternatively, perhaps some feminine readers of this weblog suppose that this sounds somewhat thrilling. Amongst newly revealed books (the titles of which I generally scan), fairly just a few are titles within the “reverse harem” style – goodreads even has its personal web page on the style.

 

There may be (or was?) a journal with the considerably improbable-sounding title of “Journal of Thermal Biology”. I’m not positive what precisely thermal biology is, however the journal revealed a paper on the thermal properties of nests of the Eurasian Tree Sparrow. Which finds that the “insulating worth of nests principally trusted their completeness and the proportion of feathers within the lining”.

The species title of the Narcissus Flycatcher was most likely not chosen with the feminine in thoughts (proven right here) – based on the HBW, “Narcissus was a lovely youth who grew to become enamored of his personal reflection in a pool and wasted away”. This was later taken up by Oscar Wilde within the story “The Disciple” (“Keats and Yeates are in your facet whereas Wilde is on mine”, The Smiths, “Cemetery Gates”).

 

Vinous-throated Parrotbills are parasitized by the Frequent Cuckoo, the Vladimir Putin of the chicken world – based on the HBW, “cuckoos’ eggs are at all times of a blue kind however bigger than these of host, and host rejected greater than 60% of cuckoo eggs when laid in blue-egg clutches and 100% when laid in white-egg clutches.”
