    The vocal distinctiveness actually has been noted already since at least 2008: ID: X6257 :XC6257 :: topic 876 :: xeno-canto

    Ardeidae

    See conclusion in my note on Great Egret vocalizations mentioned above: <<Subspecies egretta apparently doesn’t utter the rattle call, which is the commonest call in Old World races (or it is uttered so fast that it looks identical to the "rraah" call). The vocabulary of egretta consists mainly...

    Ardeidae

    Thanks Laurent for the detective work ! And the genetic tree provides great info. It would seem that there are about similar arguments for splitting Intermediate Egret and Great Egret: Considerable genetic distance, morphological differences and some vocal differences. Relatively strong cases I...

    Ardeidae

    See also my note on vocal differences between Great Egret taxa: Birds of the World In summary, it supports a species-level split of egretta from the New World, a conclusion also reached by Pratt 2011 based on different arguments.

    Subspecies groups and future splits

    Is vocal difference based on personal assessment, different transcriptions in different sources or a published comparison? E.g. Black-capped Tinamou is vocally 'green', BoW is mentioned as source, but I don't see much evidence there. Yellow-legged Tinamou is vocally 'red', but in the remarks...

    Subspecies groups and future splits

    Your project could be extended to a pre-assessment by adding 3 columns (morphology, genetics, voice) in which a -, +,++,+++ is placed resp. for zero, minor, medium or major differences and a '?' if unknown or not investigated (I remember having seen something like this for future ABA splits)...

    AOU-NACC Proposals 2023

    That's indeed an achievement in itself 😄 Nowadays, I regularly write accounts about voice of particular species for Cornell's 'Birds of the World' database. I am not particularly focusing on implications for taxonomy, but in 'Geographic variation' I do touch the topic. I think to date I have...

    AOU-NACC Proposals 2023

    Last year I spent some time analyzing a single 2022 proposal (Spot-crowned Woodcreeper) to prove that all arguments that were provided against a split were either incorrect or very subjective. This was sent to the NACC team. Judging from the comments of the team members which were published...

    Spotted Nutcracker

    A thorough study that brings support for the BLI treatment. The latter interestingly was also based on a brief analysis of voice (see Birds of the World), which found two vocal groups: fast rattling northern birds and slow rattling southern birds. The power of vocal analysis :giggle:

    AOU-NACC Proposals 2022

    No, of course not (although it doesn't hurt to highlight inconsistenties before any decision is taken :)) And given you indicated that a failure to split Lilian's Meadowlark would upset you, I thought it was wise to put things in perspective... ;) At the end, it boils down to the issue whether...

    AOU-NACC Proposals 2022

    About the Meadowlark split and vocal analysis: The proposal says: <<Beam et al. (2021) published new research on meadowlark divergence using whole-genome data and song analysis. They obtained 81 meadowlark songs and 31 whole genomes from throughout the ranges of S. neglecta, S. magna, and S. m...

    AOU-NACC Proposals 2022

    I also had a quick read and agree that some proposals lack scientific objectivity/accuracy or in some cases contain clear errors. I am just back from a birdsound recording trip to Colombia, and unfortunately have little time on my hands, but I couldn’t resist to pick a single proposal in order...

    New species of Meadowlark Strunella lilianae

    Anyone with access to this paper? I am especially interested to know whether << It also has markedly different song patterns than all other S. magna subspecies>> refers to all races in the US or North-America, or really ALL races. My own preliminary findings were that song of lilianae best fits...

    horned larks

    After a quick read of this paper, I must say that the mentioned conclusions are rather an (over-)extrapollation, for which the validity was not discussed. I would rather summarize the findings briefly as: The song of a population of peregrina from a single location was found different from a...

    The information can be found here on page 96. One holotype and one lectotype is mentioned. I am no expert in this matter :)

    Owls

    The type specimens were not assigned to the proposed species based on location but based on genetic analysis. I haven't looked at it in detail however, since it is quite confusing: the type locality for watsonii is 'Orinoco river, Venezuela' (Cassin 1848) which could be either clade A or B based...

    Owls

    I am assuming that 'east of the rio Caura' is the correct statement. XC203228 of the rio Ventuari region has a pace of 8.04n/s while XC225494 at the eastern side of the rio Caura has a pace of 9.2n/s which places them rather in the ranges of respectively clade B and A.
