Striped Owl

Mauricio Ugarte-Lewis on Birdingperu today [6 Jan 2011]:

Striped Owl form

Hi Everyone:

I am glad to inform you that with my colleagues Fernando Angulo from Birdlife/CORBIDI and Victor Gamarra from MUSA/UNIANDES, are now describing a new form of striped owl Pseudoscops (Asio) clamator, the only population of this species known from Peruvian – Ecuadorian western slope.

We have collected different records of the species in the last years, including study skins, voice recordings, photos, and comments from other observers, we also have covered most of the online resources (Xenocanto, Macaulay Library, ORNIS, etc). As far we know this new owl inhabits forested dry areas from southern Ecuador to southern Peru, we have confirmed records of at least 10 different localities in the whole range. Apparently nowadays the distribution is relictual since we had review archeological material from 800 years ago in localities with the presence of forests in the past.

The bird also have morphological differences, starting with the eye color what make the main difference with the rest of subspecies of striped owl in the rest of the distribution, some other features as measurements and body coloration are also noticeable.

Ecological differences on habitat selection and social behavior is also known, vocal differences with the rest of the subspecies are obvious but records are scarce. The genetic part of the work is ongoing and we are waiting for the final results.

We would like to ask if any of you have or is aware of someone who have any evidence of this new form of owl, we are interested in any kind of records but specially on voice records, any collected specimen, incl. tissue, bones, feathers, etc and photos. Of course any help would be formally recognized in the future publications.

Thanks in advance for any comment and help, Regards

Voice records of Striped Owl (Pseudoscops clamator)

Hi all NEOORN,

Some colleagues are studying the only population of Striped Owl (Pseudoscops clamator) of Peruvian and Ecuadorian western slope. This population have some morphological differences, with the others populations of Striped Owl in the rest of the neotropical distribution. Now, we need to confirm the voice differences.

In the last years, we have completed the collection of different records (study skins and photos). But we need more voice records, we know that these records are scarce, it is for this reason that I ask your help to know if anyone has or knows of voice records available of these populations.

We would love to receive these voice records of the population of this species from Peruvian and Ecuadorian western slope. Any help would be formally recognized.

Please contact me off the list and thanks in advance for any help.

Regards

A further, as yet unnamed subspecies has been found on the western slope in Ecuador and Peru, where confirmed records exist from more than ten localities; it appears to differ in voice, eye colour and morphology.

Don't know if this was already known, communicated via birding-aus by robert morris:Ornithological Discoveries - The work Paul Walbridge, Dave Stewart, myself and a few others elsewhere are doing on this as yet unidentified Storm-Petrel will be a major event - once we have more data. This is work in progress - it's either a long lost rediscovery (Lined Storm-Petrel - last seen & collected in the mid 1800s) or a totally new species. Watch this space - approximately 40 birds have been sighted and one examined in the hand. More field work is planned for early 2016.

Is this 'New Caledonian Storm-petrel'...?

 

[JustinJansen]

I guess so Richard!

 

[GMK]

Alice Cibois and colleagues are about to publish a genetic analysis of one of the other storm petrels sometimes thought to be the same as, or closely related to, the type of lineata, Peale, 1848.

Is anyone willing to post an anthology of the birds they know are being described, but have not yet been published? I thought about starting one from this thread, but figured someone had already done it. Thanks.

 

[reibwo]

Also, if you had to take an educated guess at which three areas/regions of the world were still most likely to contain undescribed taxa of any sort, what would those locations be and why? I have some vacation time coming up...perhaps I'll plan a trip.

If you can access HBW Special Volume (2013), Jon Fjeldså's excellent article The discovery of new bird species includes a section titled Where will the next new birds be found? reviewing the areas most likely to host unknown species.

It has been a long time I haven't shared this file. Not sure it has been properly updated since then.

Editing welcomed.

Some of these now seem to have been described:

I think it should be checked generally against the HBW new species volume also - some of those antbirds etc.

This is the best way to find a new species ():

1) Study wide-ranging pan-Amazonian "species"
2) Identify major interfluvia where there is no described form and / or specimen from that "species"
3) Visit interfluvia and describe new form as a new taxon and species
4) Have proposal rejected by SACC..but be confident that you will be proved right in the end!

cheers, alan

Thank you Thomas, spreadsheet updated accordingly.

Will do ... when I find the time.

 

[reibwo]

Daniel,

Thanks for the excellent spreadsheet. Must have taken 100s of hours to put together. Do you do it for fun?

Specimens of two Grallaria sp. and one Scytalopus sp. may represent new taxa, two of which appear to be endemic to Ayacucho (the third extends into adjacent Junín Department).

Hosner et al 2015. [pdf]

...our results suggest that three taxa—"Ayacucho" (Vilcabamba) Thistletail (Asthenes vilcabambae ayacuchensis), a "Rufous/Chestnut" Antpitta (Grallaria cf. rufula/blakei), and an "above tree line" tapaculo (Scytalopus cf. altirostris/simonsi)—are distinct and could be considered species endemic to the narrow belt of humid montane forest-puna ecotone in eastern Ayacucho (see species accounts).
...
Bay Antpitta (Grallaria capitalis).—...differences in plumage and voice are comparable to differences between other species in the bay-backed antpitta complex, and suggest that this newly found population in Ayacucho and Junín represents an undescribed taxon.
Streak-necked Flycatcher (Mionectes striaticollis).—... Recordings from Ayacucho and Cuzco and phylogeographic analyses are needed to understand the distributional limits of these vocal groups, which may constitute separate species.
