Birdwatching in the Danube Delta
Europe's greatest wetland, with over 300 recorded bird species, the continent's largest pelican colonies and a labyrinth of lakes and reedbeds best explored by boat.
Migration & season calendar
Spring (March – May)
The best all-round season. Dalmatian pelicans are back by early March, white pelicans follow in April, and spring migration fills the lakes and reedbeds. Colonies form, the vegetation is still low and the light is superb.
Summer (June – August)
Breeding season at its peak: pelican fishing parties, egrets and spoonbills with young, bee-eaters along the sandy banks, mute swans with cygnets. Go out at first light — mornings are active, afternoons hot and quiet.
Autumn (September – October)
Departure migration: summer visitors gather and head south, waders pass through, and the Delta turns gold. Fewer tourists, soft light — a favourite season for photographers.
Winter (November – February)
The quiet season. White-tailed eagles are at their most visible, and large flocks of wintering geese and swans gather on the lagoons south of the Delta — the globally threatened Red-breasted Goose winters in the Razim–Sinoe lagoon area. Boat access is limited; plan carefully.
Key species and when to see them

| Great White Pelican | Pelecanus onocrotalus | April – September; spectacular group fishing at dawn and dusk |
| Dalmatian Pelican | Pelecanus crispus | Returns early March; breeding season spring–summer |
| Great Cormorant | Phalacrocorax carbo | Year-round; colonies most active in the warm season |
| Great Egret | Ardea alba | Mostly April – October; smaller numbers stay over winter |
| Mute Swan | Cygnus olor | Warm season; grey cygnets visible roughly May – August |
| White-tailed Eagle | Haliaeetus albicilla | Year-round; often easiest to spot in winter and early spring |
| European Bee-eater | Merops apiaster | May – August only (summer migrant) |
| Eurasian Spoonbill | Platalea leucorodia | April – September |

Where to go
The inner lakes
The lake systems around Crișan — Roșu, Fortuna, Uzlina — hold the richest concentrations of pelicans, egrets, cormorants and terns. Explored by small boat, ideally at slow speed or by kayak.
Crișan & Mila 23
The classic central bases: fishing villages with guesthouses on the water, local guides and the shortest runs to the colonies. Mila 23 sits on the quiet Old Danube, perfect for kayaking.
Letea & the lagoons
The Letea forest with its dunes adds raptors and songbirds, while the Razim–Sinoe lagoons to the south host huge flocks of wintering geese — including the Red-breasted Goose.
