We are from Neotropical ornithological stations situated between Yucatan, Colombia, Ecuador and Peru. Countries, bio-regions and places that boast the greatest bird diversity on the planet. We ring all the year round often in places where investigation of this kind has never before taken place. We set up constant effort sites where our work includes satellite marking, the marking of juvenile flamingoes, terns and waders and other long term projects. Also, making use of our expertise and equipment, we help colleagues in Africa and Asia to set up related projects and activities.
