摘要：In Romania, the Greater Flamingo (Phoenicopterus roseus) is considered an Extant & Vagrant species. However, this status asked to be reconsidered in the spring of 2021, when they began to appear in flocks in the south-eastern part of the country, in the territory of the Danube Delta Biosphere Reserve and its surroundings, especially over the lacunar complex. The first two flocks (with a total of 116 birds) appeared in May but the numbers increased gathering adults, immatures and juveniles. The highest number of flamingos recorded was 265, but the flock was not stable, usually splitting, moving or disappearing temporarily, dealing also with anthropogenic disturbances. One individual was ringed, what allowed us to state it was born in the south of France. Although some adult birds displayed rituals and behaviour characteristic for breeding, we did not find any colony or nesting place and the timing of the observations does not support a successful breeding attempt. It is quite plausible that most of these birds come from other colonies, most likely those on Lake Tuz, in Turkey, where this year an ecological tragedy caused the loss of the entire generation of chicks. Here we hypothesize that they might have nested in other unknown colonies outside the borders of Romania. In conclusion, we cannot confirm the breeding of flamingos in the studied area and we reaffirm the vagrant character of the species as non-nesting summer guests.
