In winter many enter towns, where rivers usually stay unfrozen and food, including household waste, is available.

Seasonality in Romania

Resident in Romania but very mobile outside the breeding season. In winter gulls from elsewhere arrive, while some Romanian breeders winter abroad.

About this data

Source-verified months inform the seasonal filters. Local timing can vary. Unconfirmed months do not imply absence. Presence verification is separate from monthly status; each month's details identify its verification. Lighter bands mark estimated timing. Empty event rows mean no event is recorded, not confirmed absence.

Breeding

Breeds in dense colonies, often on islands, from April or May; 1–3 eggs on a scrape lined with plant material and feathers. The Romanian population is estimated at 3,500–8,000 pairs.
