    (not my record): Raven or Large-billed Crow | Sapporo, September 2023

    I am often trying hard to find the common things that Common Crows share vs what Large-billed Crows share in Japan. The clear Common Crows are obvious, the clear Large-billed Crows are a lot more obvious...and then there is the odd Raven... Not usually in Honshu or farther south, but in...

    Hooded Crane x Common Crane or Common Crane | Izumi, JP | March 2020

    Good day all, I have been doubting the ID of this distant crane in farm fields surrounding the Izumi Crane Center in Southern Japan. https://www.inaturalist.org/observations/113082644 First I thought it was a nice 2CY Common Crane, albeit a bit pale. Then I stumbled upon this 'front page'...

    distant rattle sound recording: Taiga/Red-breasted Flycatcher or something else entirely | Hegurajima, JP | may 2018

    I was happy to squeeze out a label for this rattling call of a small bird somewhere in the thick growth on the central part of birding heaven Hegurajima (in the Sea of Japan): 'it could well be a Red-breasted Flycatcher' said Xeno Canto's main Japan responder as a reply to my post in the XC...

    [someone else's record] Common Sandpiper?? | Yokohama, jp 2023/11

    I came across this bird with bright green yellow legs, strong supercilium in the Inaturalist records. I am happy to accept an ID as Common Sandpiper, but can Spotted Sandpiper juvenile be properly ruled out? Common Sandpiper (Actitis hypoleucos) I have been reading quite a bit about the duo...

    not my record: difficult Orthetrum: near Amami, Japan

    On my regular rounds around inaturalist's Japan section I came across this record of an 'Orthetrum' female. I was astounded by the clean black and yellow thorax stripes and the head that did not seem to fit Orthetrum for me (with very little field experience in Japan). On 2nd thought, I think...

    not my record: What would you make of this rather dark Stonechat | Hokkaido, JP | aug 2023

    I try to make sense of the Stonechat taxa in Eurasia but I have some trouble doing it. What would you make of this bird? (As stated above: I am not the recorder, just one of the many lay users/reviewers at inaturalist) Recorder: orthoptera-jp) origin record: Stonechats and Bushchats (Genus...

    description only: smallish brown birds with 'whitish rails' on back | Drentse Aa, NL | 10 June 2023

    Unfortunately no recording or photo... Unidentified bird - Aves indet. 2023-06-10 | Waarneming.nl I was looking for a way through a mostly dry forest on the banks of a brook in nature reserve De Heest, Drentse Aa, Northern Netherlands. Objective was: to find the River Warbler that was found in...

    rubbish recording...still worth a shot? faint vivid warbler song | end of may | Lanaye, Northern Belgium

    Good morning all, I hate to present this almost inaudible file to you people. It is a reminder to not use the app I used for recording but stick to filming with my 7dii Canon camera for the best sound result. During a Maastricht to Maastricht hike via the Lanaye peninsula my attention was drawn...

    not my record: pale Pied Wagtail | Japan, January 2023

    This bird showed up in the inaturalist records yesterday; location is obscured. A very pale white wagtail. My layman's mind says it is not dissimilar to ocularis Pied Wagtail (pretty rare in Japan) but I have been wrong before. What would you say? White Wagtail (Motacilla alba) photo borrowed...

    another one via inaturalist: 'just' hybrid Mallard x Eastern Spot-billed Duck | NW Tokyo | march 2023

    Dear those interested, Note: this is not my record/photo, I am just passing on information as I deem it interesting for the greater BF community. This duck has been id'd on inaturalist as a hybrid Mallard X Eastern Spot-billed Duck male. It looks a bit domestic Mallard x Eastern Spot-billed...

    bleached photo warning: bird in pine tree | Ees, Netherlands | February 2023

    A fellow volunteer nature guide posted this in our appgroup, I suggested i have a go at it, and then i got stuck fast. Of course, the bird on this bleached out phone photo is near impossible to ID with certainty, but I still think it may be helpful in some ways to look at bad photos and try to...

    (not my record): Ferruginous Duck hybrid? | Greater Tokyo | feb 2023

    This duck turned up on my daily check of Japanese inaturalist bird records. I thought it might be a female Ferruginous. An English forum on Japanese birds suggests it might be a Baer's hybrid. Any thoughts on its ancestry? Ferruginous Duck (Aythya nyroca) Again: this is not my record... I have...

    ad winter gull | Choshi harbor, Japan | 5 March 2020

    Going over my Choshi photo series for the third time I seem to have skipped this one earlier. Pale Iris, smudgy eye-socket, partly streaked head and neck, very powerful bill; yellow with a red bib and black smudge. Mantle a tad darker than the Vega Gull photographed literally seconds before and...

    juv Song Thrush or Mistle Thrush | Groningen, aug 2013

    This (unfortunately out of focus) young bird is tucked in my archive as juv Mistle Thrush, also admin confirmed at waarneming.nl*. Inaturalist-users don't buy that and at least the main reviewer of thrushes there says it is Song Thrush... I remember having studied it quite closely (at my pc) and...

    pale (aberrant?) finch | 3 October West aan Zee, Terschelling nl

    This is the best I got from a finch I saw quickly disappearing in thick thorn bushes just behind the coastal dunes on Terschelling Island. Any thoughts? cheers, G erben

    2nd CY gull | 5 March 2020 Choshi harbour, Japan

    Here we go again.. After my Thayer's refind has been approved (at observation.org) I keep looking for id´s. This not so very well documented 2CY gull I saw speeding past near the river mouth at Choshi. It looks to me quite a bit like other Glaucous-winged Gulls but I think the photos do not show...

    Pomarine Skua - right? | 2020 march 8 | 12km off Izu Oshima Island, Japan

    An early-season search of seabirds in my archive made me return to this set of photos of a skua some 12 km NE of Izu Oshima Island, Japan on March 8, 2020. (close to the southern tip of the Boso or Chiba peninsula) I think it is a Pomarine Skua but I have little experience with skuas and would...

    Lanceolated Warbler? | Inba Numa, Chiba, Japan | may 2018

    I have been busy uploading Japanese records to observado.org, inaturalist and a bit of ebird for a few years now. I had Japan 2018 almost completed, yet a few puzzles remained. One was this soft rattle of which I noted down; "a bit like Savy's Warbler". I did not really put energy in it as I...

    long shot: Common Snipe (?) in flight | Izumi Crane Center, Kyushu Japan | march 2020

    Morning all, While scanning the fields with scattered Hooded cranes feeding this snipe was probably flushed by a Hen Harrier. I managed to get some rubbish shots with the subject at least in it... I know this is a difficult species group anywhere, not least in East Asia. The crop compilation...

    snipe | march 2020 | Izumi, Southern Japan

    This is the one group i fear to have to delve into but there it is was: a flying snipe in the fields surrounding the Izumi Crane Center in Southern Japan, march 2020. I only have these flight shots which are not even half-decent, but is there something in there that determines its ID? I...

    One of the thrushes...but which one? | 10 March 2020 Izumi, Kagoshima, Japan

    Thrush spec: observado.org link Sho, Izumi, Kagoshima, Japan | 10 March 2020, 8:52AM location: 32°04'49.8"N 130°16'47.3"E · 1272 Shō, Izumi, Kagoshima 899-0435, Japan (approx. 1 km south of the Izumi Crane Center) I have not even noted down this record in my obsmapp app at the time, probably...

    petrel spec or tubenose spec? | Off Oshima Island, Japan | 8 March 2020

    Hi, still working on my stormy day at sea: a ferry trip from Hachijojima to Tokyo on 8 March 2020. 99% of birds that day appear to be Streaked Shearwater 0,5% is one of the three albatross species I was lucky to see (Laysan common, the other two only 2-5) And then there are these that are some...

    Not a Thayer's....right? ad. winter large white-headed gull | Choshi harbour, Japan | march 5 2020

    I have been trying to determine what this is myself for quite some time now. But I fail to see what others seem to clearly see: something is or is not a Thayers Gull. It is a bit like a firstgrade student trying to solve a 5th grade puzzle with only the firstgrade tools and knowledge. So here...

    all dark storm-petrel with forked tail | 15km East of Toshima, Japan | 8 march 2020

    I have been going through my still unseen archive of shots fired on my last japan trip (foreshortened by covid risk increase). What would you make of this bird which in the field I put down as storm-petrel spec. There are a few all dark, fork-tailed storm-petrels in the area. I think Tristram's...

    seabirdwatching potential new ferry route between Eemshaven NL and Kristiansand NO

    Good morning, after having had 2 two nice ferrytrips to the Tokyo Islands in 2018 en 2020. I started wondering if such a thing would not be nice to do for a birding trip in the Northsea. Now this week news came out that a ferry is going to take up a new route from the Northern Netherlands to...
