Lynx Edicions and the Cornell Lab of Ornithology join forces on HBW and IBC

We are pleased to announce a new partnership between Lynx Edicions and the Cornell Lab of Ornithology as we join forces to create a permanent home for the Handbook of the Birds of the World, along with the Internet Bird Collection and its passionate global community of contributors. These two projects will undergo further expansions and enhancements in their new digital home at the Cornell Lab, benefitting from the Lab’s technological infrastructure for supporting web-based publications, the Macaulay Library’s 100-year legacy of media archives and capabilities, and the rapidly growing data resources and global birding community of eBird.

Updated Species from the 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 continued updating species of Muscicapidae (Old World Flycatchers and Chats).

At the same time, we are adding multimedia links to the completed “new species”, with the family Dicaeidae (Flowerpeckers) completed and Nectariniidae (Sunbirds), Sittidae (Nuthatches) and Ploceidae (Weavers) under way.

Here are six examples to browse:
Plain Flowerpecker
Plain Flowerpecker
(Dicaeum minullum)
African Spotted Creeper
Sumba Flowerpecker
Sumba Flowerpecker
(Dicaeum wilhelminae)

Bahama Nuthatch
Maroon-bellied Sunbird
(Leptocoma brasiliana)
Red-cowled Widowbird
African Spotted Creeper
(Salpornis salvadori)

Bahama Nuthatch
(Sitta insularis)

Red-cowled Widowbird
(Euplectes laticauda)

The multimedia links we add to the accounts enhance the comprehension of the already detailed texts. Some of our recent favourites include links to all species of genera Dendropicos, Colaptes, Mycerobas and Pheucticus. We hope you enjoy them as much as we have!

2.1 billion birds cross the Gulf of Mexico during spring migration

A new study combining data from the citizen science platfom eBird and 11 radar stations used during 21 years of surveillance (1995–2015) estimated an average 2.1 billion birds pass through the Gulf of Mexico in just 18 days, between 19 April and 7 May. The timing of peak spring migration was consistent over 20 years along the 1680-mile coastline. However, they found that the earliest seasonal movements through the region occurred significantly earlier over time (1.6 days per decade). Additionally, body mass and migration distance explained the magnitude of phenological changes, with the most rapid advances occurring with an assemblage of larger‐bodied, shorter‐distance migrants.

Montane birds are declining in Europe

An international team of authors has compiled an initial account of the population trends of 44 bird species from four major European mountain regions: Fennoscandian, UK upland, south‐western (Iberia) and south‐central (Alps), covering 12 countries. Overall, the upland bird species declined significantly (−7%) during 2002–2014, a similar rate to that affecting European common birds during the same period. Montane specialists showed a significant population decline of −10%. Alpine habitats are highly vulnerable to climate change, which is certainly one of the main drivers of mountain bird population trends. However, observed declines can also be partly linked to local changes in land use. In general, in Europe montane birds are declining less markedly than farmland birds but to a greater extent than forest birds. The severe declines of farmland birds are mainly driven by agricultural intensification rather than by climate change. However, climate change can have a more profound impact on montane specialists, whose climatic niche is shrinking physically, driving these species to higher elevations where these exist and ultimately to local extinction where they do not.
