    How do birders want species-definition to be determined? Via Morphology, assortative breeding, or DNA analysis?

    it is easy to toggle between vernacular names - including between US and UK English names but you can't toggle between taxonomies as that would require restructuring the entire database, eBird, BOTW and Merlin accounts for all the different taxa etc etc. Better to continue moving towards a...

    Thanks Xenospiza. From de Knijff 2014's explainer of the Science paper One particular 1.95-Mb segment, on the avian chromosome 18, showed clear genetic differentiation between carrion crow and hooded crow individuals. This region encompassed 81 of all 83 fixed differences [of 8.4 million...

    Not really. Its like saying let's lump the Arctic Warbler complex or even the treecreepers as they are hard to ID - despite being field identifiable at times. What other examples apart from the Pterodromas upset you?

    Have a read of New research: Redpoll species are all one they aren't recognising each other which is why there is geneflow.

    There is a relatively narrow and stable hybrid zone between the crows but massive genetic admixture between redpolls. Who said they were similar in NL?

    Examples that upset you that are widely-accepted at the species level?

    I don't miss the point - you wanted to lump Zino's which is field identifiable in #15. Desertas has yet to be split by all authorities and may yet prove to be field identifiable. I can't ID various vizmig passerines but that doesn't mean we need to lump them - if you feel upset by seawatch views...

    Given that logic it maybe best to lump all 'jaegers' too as these are routinely misidentified on seawatches (and even when sat on reservoirs inland), then you can just tick 'Jaeger' or 'Small Skua'. One problem with this taxonomic concept is the historical geneflow between Pomarine and the...

    USFWS have got that now. They really need to invest in saving what remains of the insular avifauna of Hawaii.

    I heard that USFWS are working on sasquatch instead as it is more likely to be recoverable https://sasquatchchronicles.com/forums/topic/official-usfws-training-center-discussion-on-sasquatch-video/ my mate who is on QAnon says it is dead legit. Deep state conspiracy to delist IBWO by XXXXXX.

    If IBWO were extant I would anticipate sightings of birds out of habitat. Of course documenting them would be easy in that case.
