Breeding behaviour and conservation of Charadrius falklandicus and Charadrius modestus.

Collection of data related to the reproductive behavior of two species of shorebirds (Charadrius falklandicus and Charadrius modestus). These data consist of identifying of nesting sites, number of eggs in the nests, monitoring of the nests, sampling of chickens and adults. All this to understand in the long term how it has affected in their history of life (the absence of mammalian predators) in the population dynamics of both species.
