Red-billed tropicbird

This monitoring programme aims to assess the Red-billed Tropicbird population sizes and population changes. Since not all birds in the population are breeding every year, this programme provides a measure of the individual population size and its relationship with the number of nesting pairs. Additionally, with this information one can gain insight in the variation within and between colonies, between islands, years and pre/post conservation efforts.
