Some photos from Japan last year (sadly most of hand-held birds) part 4: Buntings, sparrows and finches
If anything, Japan should be known for its buntings, for there are (at least) 25 species recorded, of which three are endemic or near-endemic. Most of these pictures will be of juveniles, as that’s what we caught most of, and it can thus be a bit tricky to tell them apart.
The most common one in our catches was undoubtedly the Black-faced Bunting
Emberiza spodocephala:
which in Japan comes in two subspecies:
With the continental
spodocephala to the right, and the Japanese near-endemic
personata to the left. The former can be recognised by its lack of yellow on the body, and the greyer head and back. Brazil (1991) claims that
spodocephala is only a rare migrant, which is not really my experience. Perhaps every twentieth Black-face we caught was a
spodocephala, and I think we caught something like 3000 Black-faces in total while I was there. So they are quite common, at least in Hokkaido.
Second most common in the catches in Northern Hokkaido was the Grey Bunting
Emberiza variabilis, another Japanese near-endemic. While the female is rather nondescript:
The male is the very poster child for.. slate or lead coloured or whatever that colour is:
Some kind of blue, perhaps? The Japanese name – Kuroji – means “Black Sparrow”, which I guess is as fitting as “Grey Thrush” (called Kuro-tsugumi” = “Black Thrush” in Japanese).
The third most common bunting on Hokkaido was the Rustic Bunting
Emberiza rustica:
(though this picture is from Fukushimagata, north of Niigata on Honshu). This and the Arctic Warbler (see part 2) have some of the strangest migration routes of all Passerines. Both species breed in Northern Sweden, and fly across Asia and Japan to winter in the Philippines and East Asia. Only the curious Amur Falcon
Falco amurensis has a more unexpected migration route of the birds I know about.
Hokkaido gave only one more bunting, the Reed Bunting, which is the same species as the one in Europe (
Emberiza schoeniclus), but of subspecies
pyrrhulina:
The other “common” Reed Bunting over there is the near-endemic Japanese Reed Bunting
Emberiza yessoensis:
The name is from an old spelling of Ezo, the old name for Hokkaido, where it ironically doesn’t breed, though it apparently used to. It is quite widespread in the Amur area as well. It’s much smaller and more graceful than the Reed Bunting, and the males are easy to tell apart. The females and non-breeding males are a bit harder, especially as you run the risk of having Pallas’s Reed Bunting
Emberiza pallasi in Japan as well (I didn’t see this one), but Japanese Reed Bunting is never striated on the flanks and upper rump.
We got a lot more species at Fukushimagata, including the rare Yellow-throated Bunting
Emberiza elegans:
Here a juvenile, which looks nothing like the adults. In fact, I was not able to tell what it was when I saw it, and still am not quite sure that this photo is actually
elegans. I will look through my notes again and update if I find that it isn’t. Either way,
elegans is one of the many continental species that appear every now and then in Japan: Yellow-browed Bunting
Emberiza chrysophrys, Tristram’s Bunting
Emberiza tristrami, Little Bunting
Emberiza pusilla, Yellowhammer
Emberiza citrinella, Ortolan Bunting
Emberiza hortulanaBlack-headed Bunting
Emberiza melanocephala and Chestnut Bunting
Emberiza rutila, of which I saw none.
We did get quite a lot of these Siberian meadow Buntings
Emberiza cioides, though:
Which goes “thyyy” when you hold it in your hand, a bit similar to Meadow Pipit. Probably the cutest of the lot.
The only true endemic is this one:
(male)
(probably female or young)
Japanese Yellow Bunting
Emberiza sulphurata, an unbelievably small bunting. The last one is the Chestnut-eared Bunting
Emberiza fucata:
which I can’t remember if we had on Hokkaido, but we did have it a lot on Honshu. The brown ear covers and the characteristic, but hard to describe, head patterns are indicative of this species, which like the Grey Bunting and the Meadow Bunting is also much larger than most of the others.
It should be mentioned, perhaps, that I saw very few of these species outside the nets. Only at Fukushimagata and at Hamatombetsu were there large flocks hopping around in the reeds or on the ground, and these flocks were mainly
spodocephala and
schoeniclus.
Japan has NO resident House Sparrows
Passer domesticus. I recall having seen a report that they had had their first straggler in 2005 or so, so there’s at least one record, but otherwise they only have Tree sparrows
Passer montanus in the cities. There is another species in more rural areas, the Russet Sparrow
Passer rutilans:
And at a distance, they can be hard to tell apart and often occur in mixed flocks in smaller villages. However, whereas the Tree Sparrow female is more or less identical to the male, the Russet Sparrow female looks like a House Sparrow female. The males can be told apart on head colour (brown in Tree, obviously russet in Russet) and the lack of the black cheek patch in Russet. Tree Sparrow is also marginally larger, but while that feels obvious in the hand, it’s nothing of the sort in the field.
Moving, finally, to finches, there’s really only a few I had much to do with. While there are both Siskin
Carduelis spinus and Redpoll
Carduelis flammea in Japan, we never caught either, nor any Grosbeaks (Chinese
Eophona migratoria, Pine
Pinicola enucleator, or Japanese
Eophona personata). We missed all Bramblings
Fringilla montifringilla, Pallas’ Rosy Finches
carpodacus roseus, and Rosy Finches
Leucosticte arctoa by leaving Hokkaido too early, and the Rosefinch
carpodacus erythrinus by being in the wrong part of the island. There’s Red Crossbill
Loxia curvirostra and Two-barred Crossbill
Loxia leucoptera, but we never once went to the right sort of place. We did catch some Hawfinches
Coccothraustes coccothraustes and some Bullfinches
Pyrrhula pyrrhula griseiventris (with grey chest and stomach), but they were all juveniles, and I have no good pictures of them. The only finches I got good pictures of are the adorable Benimashiko, or Long-tailed Rosefinch
Uragus sibiricus:
And the Kawarahiwa or Oriental Grenfinch
Carduelis sinica:
This species occurs with two subspecies, the resident
kawarahiba and the migrant
sinica, and we caught both. The one in the picture I would say is
sinica, which generally is larger and has a darker head, but I found it hard to tell them apart unless you had both at once. I seem to recall that
sinica had much more white on the primaries than
kawarahiba, which also speaks for the one in the picture being
sinica. If I find any good comparison pictures, I will post them as well.
We end with an unknown species of spider that was very common in the Tokyo area:
