Habitat changes in Laguna de Pozuelos, Jujuy, Argentina: Implication for South American Flamingo populations

The three South American flamingos, Chilean Flamingo (Phoenicopterus chilensis), Andean Flamingo (Phoenicoparrus andinus) and James' Flamingo (Phoenicoparrus jamesi), coexist in Laguna de Pozuelos (Jujuy Province, northwestern Argentina). This lake is an important overwintering habitat for Ande...
