Francisco Cornell  :  He is my choice for the extremely diverse Northwest Argentina. Living in Jujuy since a child, he travelled and explored his region extensively. As a self-taught birder, with fluent English, he has developed good ability in finding and identifying birds by their sounds.
Guide for foreign birders since 2000, he is official guide at the Calilegua National Park; co-authored the Bird Checklist of the Jujuy Province and took part in bird censuses and conservations projects.
Francisco works for the official board of tourism, is married and has two kids
