Long-Term Changes in the Breeding Success of the Dalmatian Pelican Colony in the Srebarna Nature Reserve (NE Bulgaria) and Conservation Measures Over the Years

A long-term study (1955–2024) of the Dalmatian pelican colony in Srebarna Nature Reserve, Bulgaria, reveals a significant improvement in breeding success over decades despite recent declines. The number of nests fluctuated between 7 and 150, with a notable downward trend in the last five years. Conservation measures, such as raised wooden platforms and protective fences, have proven effective in maintaining the colony's viability. However, external factors like human disturbance, predation by invasive species, and competition from alternative nesting sites pose growing threats. The study underscores the need for continued conservation efforts to ensure the long-term survival of this vulnerable population.
