9000 species with videos on the Internet Bird Collection!

The Internet Bird Collection (IBC) is an important sister-project to HBW Alive and is the most globally comprehensive website of audiovisual materials of the birds of the world.

We are proud to announce that the IBC now has videos of more than 9000 bird species. Specifically, as of today, there are 120, 263 videos of 9016 bird species, many showing rich behavioural information. This is an invaluable collection that hasn't been assembled anywhere else before. This new IBC record is especially remarkable considering that the number of people taking bird videos is much less than those dedicated to bird photography. The record-breaking video was of Snow Mountain Tiger-parrot Psittacella lorentzi by Hervé Jacob, who has been uploading some tremendous videos of his last trip to New Guinea – thanks, Hervé!

We extend our sincere gratitude to everyone that has joined and contributed to the IBC over all the years, helping us to achieve this and many other goals, like an astonishing 10,339 bird species with photos and 6585 bird species with sound recordings.

But, of course, there are many more records to be broken. There are still species without videos, photos or sound recordings on the IBC and places in the world where no contributor has set foot... Here you can find three lists that show species that lack videos, photos or sound recordings, so that together we can fill in more gaps and cover more species.

And how does all of this relate to HBW Alive? Well, right now more than 6500 species accounts in HBW Alive have multimedia links and we continue adding more. As IBC multimedia links in HBW Alive are conveniently displayed directly in the species page (instead of in a new window), we prioritize these links and are constantly reviewing new IBC contributions to see where they may enhance HBW Alive information.

So, we encourage you to get out there and keep taking bird videos, photos and sound recordings and to share them with the IBC community and, thus, with the HBW Alive community as well!

Updated Species from the Checklist

Updated Species from the Illustrated Checklist

Our efforts continue with updating the passerine splits derived from Volume 2 of the Illustrated Checklist, both the original “mother” species and the resulting “daughter” species.

Last month we completed all “new species” (resulting from splits) of the families Polioptilidae (Gnatcatchers), Remizidae (Penduline-tits) and Malaconotidae (Bush-shrikes). We also continue adding multimedia links to the completed “new species”, with Pycnonotidae (Bulbuls) and Polioptilidae (Gnatcatchers) finished.

Here are four examples to browse:
Aceh Bulbul
Aceh Bulbul
(Pycnonotus snouckaerti)
 Olive-headed Bulbul

What do coloured bullet points mean in the “Subspecies and Distribution” section?


Just a reminder that the colour-coded bullet points in the Subspecies and Distribution section of the Species accounts mark “subspecies groups”. These are informal taxonomic units used to highlight seemingly monophyletic groups of taxa (sometimes single subspecies) that at present appear to sit between the species and subspecies levels. The black bullet points mark subspecies that do not separate into such groups.


Furthermore, the same colour coding system used for the bullet points is repeated in the illustration section of the species page; the same colours are used in the headers for the figures of each subspecies, clearly marking the same groups and helping the user make clearer connections between the texts and drawings.

Unlike adults, juvenile Streaked Shearwaters overfly mountains during their first migration


Telemetric studies have shown that juvenile Streaked Shearwaters Calonectris leucomelas from a colony in the north of Honshu Island, Japan, take a different route from adults during their first southward migration. Juveniles orientate south, resulting in an overland crossing that includes mountains. Adults travel over water, around the land mass. Experience, thus, seems to modify an innate tendency to migrate south, so that birds remain in contact with the marine environment.

This species was first described by T. A. Parker and O’Neill in 1985 as Thryothorus euophrys schulenbergi, the subspecific name “schulenbergi” honoring Dr Thomas S. Schulenberg, a US ornithologist, ecologist and conservationist at the Cornell Lab of Ornithology, who is an important author and editor of ornithological works, including of our own HBW.
