A lot has changed since the first Checklist of the Birds of REGUA was published in November 2010. The taxonomy and nomenclature of many South American birds has changed enormously as molecular studies reveal a better understanding of cladistic relationships. A further 10 bird species have also since been added to the REGUA list bringing the total up to a whopping 462, which surely makes REGUA one of the most avian rich reserves on Earth for it's size.
I've updated the list to include the latest taxonomy adopted by the CBRO (Brazilian Committee of Ornithological Records), and this edition also has all text in Portuguese as well as English. I've included revised seasonal abundance data for many species, and to the best of my knowledge this is still the only checklist for any site in Latin America that includes abundance/movement bar charts (click on the image below to see a preview of selected pages).
The list is currently with the printers and will be available for purchase in the UK (as well as Brazil) from this Saturday. If you would like a copy please email me at email@example.com. Copies cost £3 plus £1.60 postage, and all funds go towards REGUA's conservation work.
