As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

March of the multiple penguin genomes

The Penguin Genome Consortium sequences all living penguin species genomes to understand the evolution of life on the ice

Published today in the open-access journal GigaScience is an article that presents the first effort to capture the entirety of the genomic landscape of all living penguin species. The Penguin Genome Consortium —bringing together researchers from China, Denmark, New Zealand, Australia, Argentina, South Africa, the UK, the US, France and Germany— has produced 19 high-coverage penguin genome sequences that, together with two previously published genomes, encompass all surviving penguin species. This extensive study provides an unparalleled amount of information that covers an entire biological order, which will promote research in a wide variety of areas from evolution to the impact of human activities and environmental changes.

Penguins are a diverse order of species that span the Southern hemisphere, ranging from the Galápagos Islands on the equator, to the oceanic temperate forests of New Zealand, to the rocky coastlines of the sub-Antarctic islands, finally reaching the sea-ice around Antarctica. This iconic bird group have transitioned from flying seabirds to powerful, flightless marine divers. With their specialized skin and feathers and an enhanced thermoregulation system they are able to inhabit environments from the extreme cold Antarctic sea ice to the tropical Galápagos Islands.
