Improvements keep coming in HBW Alive!

We'd like to announce two new improvements to increase the functionality of HBW Alive and the available information:
  • New search tool
  • Contribution maps
The new search tool allows you to search the site by English common name and scientific name. Once you have typed some letters, a list of options is displayed from which you can choose. More information about this new tool is detailed in the HBW Alive Features section below.

In the Maps block of the species accounts and the family chapters you will find a new Contributions map, which anonymously displays aggregated data from the IBC and My Birding. This is a great tool to discover the locations where a species is most commonly seen!

For some particular species this map supplies remarkable information, like for long-distance migratory species and seabirds, as you can find out where they are most often observed. It is also informative for species with established populations outside of their native distributional ranges, as you can easily see how they have dramatically increased their ranges.

We hope you enjoy these two novelties and please know we are always working on more improvements! For example, we are currently developing new analytics tools for My Birding that will greatly augment your interaction with your birding data and make it easier for you to plan your birdwatching trips!

New Species from the Checklist Updated

New Split Species from the Illustrated Checklist Updated

As explained in our April Newsletter, we have been focusing our efforts on 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 the 43 “new species” (resulting from splits) of the family Furnariidae (Ovenbirds) and we started on Campephagidae (Cuckooshrikes). We've also continued to add multimedia links to the completed “new species”, with Thamnophilidae (Typical Antbirds) and Conopophagidae (Gnateaters) finished and Grallariidae (Antpittas) under way.

Here are six examples to browse:
Streak-fronted Antshrike

Northern White-fringed Antwren

(Formicivora intermedia)

(Conopophaga cearae)
Species with Multimedia Links
We are always busy adding multimedia links to the accounts to enhance the comprehension of the already detailed texts. Some of our recent favourites include links to four genera of Picidae, specifically the 12 Campephilus species, 14 Celeus species, 5 Hylatomus species and 3 Dryocopus species. We hope you enjoy them as much as we have!
Celeus species
Pied Thrush
Check out these “Top 5” species with recently incorporated multimedia links: Great Sapphirewing (Pterophanes cyanopterus), Twelve-wired Bird-of-paradise (Seleucidis melanoleucus), Chestnut-crowned Warbler (Phylloscopus castaniceps), Pied Thrush (Geokichla wardii) and Pink-throated Twinspot (Hypargos margaritatus).
HBW Alive Features
As explained above, the new search tool allows you to search by English common name and scientific name. Once you type in the English or scientific name of the species, genus or family that you are looking for, you get a drop-down list of options from which to choose.
To make things even easier (and to avoid problems with typos!), for scientific names, you can search by typing just the first three letters of the genus and the first three letters of the specific name. For English common names, you can try typing just the first three letters of the name.
In case you are looking for the generic common name that matches the family's English name, the family is shown first in the displayed results. Subspecies groups are also displayed if they match your input. And you can perform the search with the English name of the subspecies group you are looking for.
With these improvements, now it is easier to find the information you are interested in.

Does Wilson’s Storm-petrel breed in the Andes of Central Chile?

Wilson’s Storm-petrel (Oceanites oceanicus) is known to breed in antarctic and subantarctic latitudes. The subspecies chilensis breeds in Tierra del Fuego but there is increasing evidence that it may also nest in the Chilean Andes. Recent analyses have now revealed an occurrence pattern among the 49 birds found in the central Chilean Andes and nearby between 1920 and 2016 that strongly suggests the existence there of hitherto unknown breeding colonies. All the records are from a 500 km stretch of territory and over 90% were between San Felipe in the north and Rancagua in the south, a separation of only 160 km, at distances from the coast of 67–157 km. All were found between November and May, over 85% in April–May, and many of those found in April-May were juveniles.

The European Goldfinch is severely threatened by poaching in northwest Africa

The European Goldfinch (Carduelis carduelis) has been used as a cagebird for centuries. In the western Maghreb countries of Morocco, Algeria and Tunisia, a recent study shows that poaching is still a major issue, having in fact increased dramatically since 1990. In Algeria prices have exponentially grown so that one goldfinch is currently worth nearly a third of the average monthly income. Nearly 57% of the species’ distribution range has apparently been lost in the western Maghreb during the past 26 years, being already extinct or very scarce in Tunisia and most of Algeria, except for the western part. Recently poachers started to use mist nets, and this is thought to impact other Afro-Palearctic migratory birds as well.

The first ornithological field guide covering New Guinea, Bismarck Archipelago and Bougainville. With over 1780 illustrations, it describes all 943 species known to occur in the region, including the extraordinarily high total of 456 endemics, as well as 5 introduced species, 2 species yet to be formally described and a separate appendix with 75 vagrants. Subspecies are listed also to give a comprehensive overview of the remarkable regional avifauna.

Rodents include species that have colonized almost every available habitat on earth, and others that have adapted to human beings and followed them as they also spread across the globe.
Volume 7 completes the order Rodentia—which represents arguably the most important order of mammals, both in terms of number of species, and in geographic distribution—covering the families contained in the suborder Myomorpha, including the two largest families, Cricetidae and Muridae.
