Richard (with thanks to Fernando Angulo Pratolongo for forwarding on NEOORN)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

Thurber, Lohnes & Schulenberg 2009 (Neotropical Birds Online).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.
