The breeding season in Persina Nature Park and the Kalimok-Brushlen Protected Area has ended

July 15, 2022

Unfortunately, 2022 turned out to be an unkind year for the Dalmatian pelican of the Balkan Peninsula. In the spring, more than 2,000 adults from breeding colonies in Greece and the Danube Delta in Romania died as a result of avian influenza (the so-called bird flu). This resulted in nearly 40% decrease of the population of the species in the area!

This year 30 pairs of Dalmatian pelicans successfully raised 30 juveniles in the Kalimok-Brushlen Protected Area.

The breeding season for the Dalmatian pelicans in Bulgaria also turned out to be not so good. Due to the extremely low level of the Danube river, water didn’t enter the marshes of Persin Island and they remained dry during the breeding season. In February, 120 Dalmatian pelicans occupied the three wooden platforms in the Persina Marshes Conservation Reserve. However, after three nesting attempts, they abandoned the platforms at the end of April. Thus, for the first time since a new nesting colony was formed in the Persina Nature Park in 2016, the species failed to raise youth. The season for pelicans, as well as other waterfowl ususally nesting in the marshes of Persin Island, was not successful this year due to the lack of water level in Peschina swamp, Dead Marsh and Old Marsh.

Nevertheless, there is also positive news. 2022 turned out to be a record year for nesting of Dalmatian pelicans in the Kalimok-Brushlen Protected Area. This year 30 pairs successfully raised 30 juveniles. The lack of water, as well as the fires that broke out, failed to drive away the birds. All the young pelicans flew away in mid-June and are currently sticking to the sandbars along the Danube River. We also would like to remind you that in April 2021 a new nesting colony of the species was formed in the protected area, where three pairs successfully raised four youngs. This is a spectacular conservation success and another effective step in the preservation of this majestic species.

In 2016, for the first time in 60 years, a new nesting colony of the Dalmatian pelican was formed in Bulgaria – in the Peschina swamp. Before that the only place where the species successfully bred in the country was Srebarna Lake. In 2020, the pelicans also successfully occupied the platform in the Dead Swamp, that is also located on Persin Island. And finally in 2021, a new nesting colony of the species was formed in the Kalimok-Brushlen Protected Area, thus the number of nesting sites of this endangered species in the country turned three – Lake Srebarna, the swamps of Persin Island and the Kalimok-Brushlen Protected Area.

The conservation activities of the Dalmatian Pelican are carried out in the framework of the “Pelican Way of LIFE” initiative (LIFE18/NAT/NL/000716), funded by the LIFE Programme of the European Union and Arcadia Foundation, and with the assistance in Bulgaria of the Whitley Fund for Nature.
