Titicaca Grebe decline

10-09-2001

A recent survey of the Titicaca Grebe Rollandia microptera has revealed that numbers have plummeted at many of its known breeding sites in Peru, apparently following the widespread introduction of gill-nets in the early 1990s. For example, at Laguna Umayo 1,147 Titicaca Grebes were counted in 1987, but the recent survey found only four birds.
