    Worth noting that there *are* photographs in the gallery of an exhibit for Pinyon Jay at Phoenix Zoo in 2010 - merely none of the inhabitants ;)

    On the off-chance that photos were uploaded but lost in the Great Purge - or merely not uploaded - I reach out to the following:

    @snowleopard
    @geomorph
    @Blackduiker

    Of course, if anyone else has photographs of this species wild or captive they would be more than welcome :)

    As you are probably aware, many taxonomists split this taxon into three species:

    Woodhouse's Scrub-Jay Aphelocoma woodhouseii
    California Scrub-Jay Aphelocoma californica
    Island Scrub-Jay Aphelocoma insularis

    Indeed - in point of fact I personally do so too, but for the sake of consistency I am keeping to the taxonomy laid forth within HBW as noted at the start of the thread.

    Similarly, this thread lumps Hooded and Carrion Crow as this is the taxonomy followed by HBW, even though I personally split the two species on my lifelist.

    Great thread! One of my favourite group of birds.
    I have uploaded a picture of Corvus corax hispanus to the gallery, in case you want to use it. From Santillana del Mar zoo.

    I am surprised HBW recognizes Northwestern Crow as distinct from American Crow, but not the scrub-jay split. The crow is extremely difficult to separate, the jays much less so. Other factors weighing in as well:

    "This long-anticipated split has finally happened. The two “new” species barely overlap in range. A recent study states that the only place this seems to happen regularly is the Pine Nut Mountains of Storey County, Nevada, and that hybridization is limited to this very small area; however, local birders report overlap in Reno, as well. Limited hybridization in addition to consistent differences in voice, habitat, behavior, and morphology, was enough to tip the scales toward a split." Quoting the ABA blog, regarding the AOU's decision in 2016

    The scrub-jays split as California, Woodhouse's, Island, and Florida seem to have been widely accepted (and indeed anticipated due to range and morphology) so far as I have seen.

    Curiously enough, the text regarding these taxa on HBW states that there is little-to-no difference in voice between them - but the last revision to this entry is noted as dating to 2013, so it is possible new genetic and behavioural evidence has come to light subsequently.

    Well, it certainly did as of a few years ago, because the photo I used illustrating the species was taken in New Zealand :p

    And that's the Zoochat Photographic Guide to Corvids completed :)

    Obviously, any subspecies which can be added will be very much more than welcome - and I certainly hope that we will have a good few more added in the coming days and/or weeks - but naturally the biggest priority will be hopefully filling gaps at species level!

    There are actually rather fewer than one would think, given the number of species we are playing with, but here are the major gaps in the Zoochat gallery in terms of corvid species:


    Malay Black Magpie
    (Platysmurus leucopterus)
    -----

    Hooded Treepie (Crypsirina cucullata)
    -----

    White-bellied Treepie (Dendrocitta leucogastra)
    Collared Treepie (Dendrocitta frontalis)
    Andaman Treepie (Dendrocitta bayleii)
    -----
    White-winged Magpie (Urocissa xanthomelana)
    Hainan Magpie (Urocissa whiteheadi)
    -----
    Siberian Jay (Perisoreus infaustus)
    Sichuan Jay (Perisoreus internigrans)
    -----
    Ethiopian Bushcrow (Zavattariornis stresemanni)
    -----
    Mongolian Ground-jay (Podoces hendersoni)
    Xinjiang Ground-jay (Podoces biddulphi)
    Turkestan Ground-jay (Podoces panderi)
    Iranian Ground-jay (Podoces pleskei)
    -----
    Asir Magpie (Pica asirensis)
    -----
    Southern Nutcracker (Nucifraga hemispila)
    Large-spotted Nutcracker (Nucifraga multipunctata)
    -----
    Cuban Crow (Corvus nasicus)
    Jamaican Crow (Corvus jamaicensis)
    White-necked Crow (Corvus leucognaphalus)
    Sinaloa Crow (Corvus sinaloae)
    Palm Crow (Corvus palmarum)
    Flores Crow (Corvus florensis)
    Piping Crow (Corvus typicus)
    Banggai Crow (Corvus unicolor)
    Slender-billed Crow (Corvus enca)
    Violet Crow (Corvus violaceus)
    Long-billed Crow (Corvus validus)
    Bougainville Crow (Corvus meeki)
    White-billed Crow (Corvus woodfordi)
    Brown-headed Crow (Corvus fuscicapillus)
    Grey Crow (Corvus tristis)
    Bismarck Crow (Corvus insularis)
    Little Crow (Corvus bennetti)
    Little Raven (Corvus mellori)
    Forest Raven (Corvus tasmanicus)
    Mariana Crow (Corvus kubaryi)
    -----
    White-throated Jay (Cyanolyca mirabilis)
    Dwarf Jay (Cyanolyca nanus)
    Black-throated Jay (Cyanolyca pumilo)
    Silvery-throated Jay (Cyanolyca argentigula)
    Beautiful Jay (Cyanolyca pulchra)
    Azure-hooded Jay (Cyanolyca cucullata)
    Quindio Jay (Cyanolyca quindiuna)
    Black-collared Jay (Cyanolyca armillata)
    White-collared Jay (Cyanolyca viridicyanus)
    -----
    Pinyon Jay (Gymnorhinus cyanocephalus)
    -----

    Unicolored Jay (Aphelocoma unicolor)
    -----
    Tufted Jay (Cyanocorax dickeyi)
    Azure-naped Jay (Cyanocorax heilprini)
    Campina Jay (Cyanocorax hafferi)
    Cayenne Jay (Cyanocorax cayanus)
    Bushy-crested Jay (Cyanocorax melanocyaneus)


    All in all, I reckon that having 79 out of 130 corvid species represented in the gallery is damn good :D but I am certain we can do better! Quite apart from anything else, I would be very much surprised if no one has photographs of at least one of the Ground-jays, the Pinyon Jay, the Siberian Jay and the three Australian natives we lack (Little Crow, Little Raven and Forest Raven). The Bushcrow might be a more distant hope, but one never knows.......

    Ah, excellent :D there are a lot of very nice corvid species which I have never seen flying around the European private trade, it seems.

    In that case, it is a genus I have never seen!

    I note many of these come from areas where few if any Zoochatters live. Though maybe through trip photos we can hopefully get some species represented! Going digging through some older photos here soon, see if I can turn up some subspecies!

    Someone's got to have Pinyon Jay... It ranges wide enough in reasonably accessible habitat, even if the species isn't really kept in zoos. The species is a thorn in the side for me as it is the only corvid I've been in the range of I've missed... Occasional visitor in my county even. :p

    Indeed, island endemics in the Caribbean and Pacific account for a lot of the missing taxa!

    As noted upthread, we have several members who posted photographs of an exhibit holding the species :p so we can but hope. It's certainly one of the missing species with the highest odds of being added to the gallery.

    Unfortunately the photo I was remembering proved to be canadensis, and very poor as I did remember. That said, I have seen obscurus at least 3 times, and they live within an hour's drive from me. Come spring when it will actually be possible to access the area they're best seen, it is hopeful I may be able to fill the gap if someone else has not!

    I noted that, with little surprise!

    I saw your request to those members, though haven't seen anything so far. I'd guess a Pinyon will show up sooner than later though.

    Florida Scrub-Jay is a very frustrating one for me as I went looking for it one day with no success. I had plans to go searching again early the following morning but I was too young at the time to go out on my own and my mother decided she didn't want me running around a preserve in general for some reason.

    I've seen over a dozen of those missing species in the wild. I'll look through my photos on the weekend and see what I can find (or not find, as the case may be. Don't expect too much).
