This 12 months, it appears I wrote one put up on birding in Shanghai every month – and I’m nonetheless not even certain anybody is interested by these. Possibly the subject is simply too bureaucratic or irrelevant? Feedback are welcome.
In all probability essentially the most fascinating fowl this month was a Gray-headed Canary-Flycatcher exhibiting up within the Shanghai Botanical Backyard. This fowl will not be uncommon in any respect additional down south, however one wouldn’t anticipate it in Shanghai in mid-December.
My try at making a Hallmark card beneath.
It is a relatively photographer-friendly species, staying on the identical department for fairly some time and even returning to it after catching some bugs – you possibly can see this on video here and here.
The Japanese Marsh Harrier is usually thought of to be a subspecies of the Western Marsh Harrier, nevertheless it appears most sources now regard it as a separate species. There may be substantial hybridization within the Baikal area of Japanese Siberia (source), just like the hybridization between Western and Japanese Germans (which sometimes even produces viable offspring).
It is a feminine.
In distinction, this (badly photographed) Siberian Rubythroat might be a juvenile male, based on one pal who’s extra certified than me to make such statements.
Not a lot purple on its throat – however nonetheless higher than this Frequent Rosefinch seen at Tianmashan.
I do know – sexism is quite common within the birding world. Okay, it could possibly be a first-year male as properly.
An older paper on this species has the relatively shocking title “Mate alternative will not be necessary for feminine reproductive success within the Frequent Rosefinch”. The logic is that “roughly 50-99% of the variance in feminine reproductive success was attributable to nest predation throughout incubation” and “males didn’t defend nest websites”. I’m not fully satisfied by this logic, however unattractive male rosefinches could learn this paper with pleasure.
Azure-winged Magpies fail to cross the mirror check, a check generally used to find out self-recognition. Whereas the source doesn’t say so immediately, it hints that this implies the species will not be as clever as Eurasian Magpies (which cross the check).
However, the birds share meals with different birds of the identical species, notably if these should not have meals (and unsurprisingly, much more notably if they’re of the other intercourse). After all, the paper ends with the standard thinly disguised request for extra analysis grants: “This sharing habits might point out a excessive degree of social consciousness and prosociality that must be additional investigated. Additional research are wanted …”
Should you use a nasty on-line translation engine to translate the Chinese language identify of the Northern Lapwing into English, you’ll find yourself with the “Crested Wheat Hen” (Fèng tóu mài ji). Someway I really feel this can be a bit degrading to the species, nevertheless it in all probability doesn’t care.
The Frequent Kestrel has a barely derogatory Latin species identify – tinnunculus, or shrill-sounding. Whereas listening to its call on xeno-canto confirms that the decision certainly is a bit shrill, it appears a bit unfair to show this into the defining characteristic of the fowl, offering its identify. It’s just like the outdated sheepshagger joke …
Trying to find papers on the Frequent Kestrel, one abstract instantly caught my consideration. It begins as follows: “Historic variations (1966–2016) within the publicity to inorganic components in raptors of South West Spain have been little studied.” The sensation of not figuring out about that is nearly insufferable.
Sadly, as soon as Frequent Kestrels run into issues that lead to them being became rehabilitation facilities, their probabilities of survival are comparatively slim – in one study, solely 16% of the birds could possibly be launched again into the wild whereas 82% died.
Another paper checked out how feminine kestrels select their companions – do they like particular colours? The authors enhanced the colours of 1 male however not one other, after which let females select. Considerably disappointingly, the females didn’t actually differentiate between coloured and management males. My speculation is that internal values are rather more necessary to them.
The positioning birdstudies.net has a pleasant cute illustration of the Gray-capped Greenfinch.
Inequality in greenfinch society is partly attributable to assortative mating – cool/enticing/wealthy/educated male greenfinches ideally mate with cool/enticing/wealthy/educated feminine greenfinches. As scientists have found. Presumably, this additionally results in revenue inequality, if parallels to people are any guidance.
Tristram’s Bunting is called after Henry Baker Tristram (1822-1906), an individual described by Wikipedia as a “parson-naturalist” who “was an early supporter of Darwinism, trying to reconcile evolution and creation.” On condition that apparently “Tristram, after early acceptance of the speculation, rejected Darwinism”, this bunting could possibly be a superb candidate for being renamed as properly (until, in fact, it seems the species was created by Clever Design).
Presumably, the photographs beneath present Swinhoe’s White-eye. However then, who could be certain? The HBW cryptically states that the “5 subspecies acknowledged as a part of Swinhoe’s White-eye right here had been till just lately thought of a part of three separate species, together with what was as soon as Japanese White-eye, now Warbling White-eye (Zosterops japonicus), what was as soon as Oriental White-eye, now Indian White-eye (Z. palpebrosus), and what was as soon as Enggano White-eye (Z. salvadori).”
This one seems a bit involved about not figuring out which species it’s. A bit like being adopted, I assume.
Why the species was named after an individual who already has given his identify to 5 different species of birds will not be fairly clear to me.
The HBW additional guarantees that the species account “continues to be being revised, and future variations of this account will absolutely mirror these taxonomic adjustments.” On condition that the present account was ready in 2016, I’m not holding my breath although.
If you wish to see a White’s Thrush consuming, you possibly can have a look here or here. This species is wintering at Tianmashan, a forest park in Shanghai, and the HBW additionally calls it a “pretty widespread winter customer in [the] Shanghai space”.
Relying on which photograph you have a look at, you may even be capable of perceive the species identify aurea, or “golden” (although it nonetheless appears a little bit of a stretch to me).
Given that almost all nests should not have operating water put in, it’s not shocking {that a} examine discovered that Pale Thrushes (and two different thrush species) constructed their nest inside 40 meters of a stream (source).
Is it the equal of a “Miss Moist T-Shirt” contest to indicate photographs of moist birds, resembling this Daurian Redstart …
… or this Pallas Leaf Warbler?
As Covid spreads in Shanghai (not an issue, it’s now not harmful, based on the Chinese language authorities), the Little Egrets beforehand spending time close to my compound withdraw to some bushes. I assume they don’t fairly belief the federal government announcement and thus follow avian social distancing …
… whereas juvenile Black-crowned Evening Herons follow their “Grim Reaper” pose.
Reed Parrotbills are getting more durable to seek out in Shanghai as the federal government has changed reedbeds with bushes (there’s a quota for bushes however none for reedbeds or parrotbills). Misguided incentives, anybody?
Possibly the parrotbills simply have to adapt and put their nests in bushes. Isn’t that what evolution is all about? A further profit can be much less nest predation by tidal mudflat crabs, the first reason behind Reed Parrotbill egg predation in tidal reed-bed habitat (source). Win-win.
This particular person is seemingly working towards some type of bizarre yoga.
The Black-winged Kite has (a minimum of in my impression) grow to be extra frequent in Shanghai previously few years. Apparently, that is a part of a broader development – it has additionally been noticed in Taiwan (source). In the long term, this may increasingly grow to be an issue for the Eurasian Kestrel because the kites are extra aggressive and should power kestrels to hunt different wintering websites (same source). In the meanwhile, a minimum of on Chongming island each species are current.
I used to be lucky to go to Chongming island on the day of the twentieth Nationwide Congress of the Chinese language Spoonbills.

Apparently, the Eurasian Hoopoe is listed within the Previous Testomony as unclean and forbidden meals for Jews. And certainly, the Tel Aviv McDonald’s doesn’t promote any Hoopoe Burgers.
Nevertheless, this makes it a bit shocking that it was additionally named Israel’s nationwide fowl.
I do know. I’ve already proven many photographs of the Daurian Redstart. Not a adequate cause to not present some extra, although.
Ditto Gray Heron.
The Gray Heron is hoping to get some sponsorship from a producer of taking part in playing cards, because it thinks it has perfected the artwork of symmetrical photographs.
Based on one paper, the Noticed Redshank is the German among the many waders, a minimum of in Finland: its arrival and departure on the breeding grounds are essentially the most predictable. Surprisingly, they solely keep on the breeding grounds for about 5 weeks. Then once more, that’s in all probability the size of summer season in Finland.
The Chinese language Gray Shrike solely involves Shanghai in winter, primarily to go to its resident relative, the Lengthy-tailed Shrike. Household ties are necessary.
And to finish this put up, a mammal.
Cute, admittedly – however nonetheless a mammal, not a fowl.
