For the seventh year in a row, the breeding season for Dalmatian pelicans in the Persina Nature Park has started. In mid-February, during the regular monitoring of the marshes on Persin Island, a team of the Bulgarian Society for the Protection of Birds (BSPB) and the Persina Nature Park Directorate found that the pelicans had occupied all the wooden platforms built for them – two in the Peschina swamp and one in the Dead Marsh on Persin Island. At the time, experts observed about 120 adult birds actively preparing their nests.
