The European Bee-eater (Merops apiaster) is a spectacular migratory species associated with open landscapes, sandy or clay soils for nesting and an abundance of flying insects. In Dobrogea and the Danube Delta area it is present from spring to late summer. Identification: multicoloured plumage (turquoise, yellow, chestnut-red), black eye-mask, slender slightly curved bill; buoyant flight, often in small groups. Ecology: specialist insectivore (bees, wasps, dragonflies, butterflies). Nests in burrows dug into banks. Observation: warm mornings near exposed banks and open fields; calls are an excellent cue for locating the species. Conservation: sensitive to changes in nesting habitat and decline in insect prey; responsible observation means avoiding disturbance close to colonies during the breeding season.

Identification

Unmistakable when seen well: a slender, long-tailed bird with vivid green upperparts, yellow throat, blue-green underparts, and a chestnut crown and back. The long central tail feathers project beyond the tail tip, giving the bird a distinctive elongated silhouette in flight. The call — a liquid, rolling prrrip — is the first indication of presence and carries considerable distance.

Field Marks at a Glance

Size 27–29 cm including projecting tail feathers.
Upperparts Green with chestnut crown and upper back.
Throat Vivid yellow, bordered below by narrow black band.
Underparts Blue-green.
Tail Green with two elongated central feathers projecting 2–3 cm.
Call Liquid rolling 'prrrip' — distinctive and far-carrying. The first sign of presence overhead.

Confusion species: Unmistakable in Europe. No other species combines these colours with the elongated central tail feathers. The European Roller is similar in size but completely different in plumage.

Sandy banks along the Caraorman canal — Bee-eater nest burrows are visible as horizontal holes dug 50–60 cm into the soft substrate.

When to See It in Romania

The European Bee-eater arrives in Romania from sub-Saharan Africa from late April. Colonies are established by early May. Breeding activity peaks May–July. Pre-migratory gatherings in August can involve hundreds of birds on overhead wires. Most have departed by September.

Where to See It

Bee-eaters require vertical sandy banks for nesting burrows and open ground for hunting. In the Danube Delta, the most accessible colonies are along the Caraorman canal and at several Dobrogea plateau locations visited on the Letea excursion day.

Colony site

Caraorman canal banks

The primary accessible colony site in the delta — sandy vertical banks with 30–80 nest burrows. Visible from the motorboat; birds perch on wires above the bank.

Dobrogea

Road cuttings and gravel pits

The plateau approach roads have exposed sandy banks with multiple Bee-eater colonies. Easily observed from a stationary vehicle.

Flight hunting

Over open water

Bee-eaters hunt dragonflies and large insects over the open channels — aerial acrobatics visible from the floating hotel deck.

Perch sites

Overhead wires

Lines of Bee-eaters perching on wires above the bank are a classic delta sight — easy photography from below.

Behaviour & Ecology

Bee-eaters are aerial hunters, catching insects in flight and returning to a perch to process and eat them. Despite the name, they take a wide variety of large insects — dragonflies, wasps, moths, butterflies, and beetles in addition to bees. The prey is struck against the perch to remove stingers before eating. Nesting is colonial: pairs excavate a horizontal burrow 50–60 cm long in soft vertical banks, with an egg chamber at the end. The colony is surprisingly quiet except during incubation relief and food delivery. Pre-migratory congregations in August see hundreds of birds gathering on overhead wires before departure — one of the most atmospheric wildlife spectacles of the late delta season.

🛡 Conservation Status

Currently Least Concern (LC) globally and expanding its range northward in Europe as climate change shifts the suitable zone. Romania remains a core stronghold, with Dobrogea and the delta among the most productive areas. The species requires intact sandy banks and open hunting habitat — both well-preserved in the Danube Delta Biosphere Reserve.

Photography Guide

Bee-eaters are among the most rewarding photographic subjects in Europe for one simple reason: they return to the same perch repeatedly after each hunting foray. You have unlimited time to compose, wait for the right light, and select the moment.

📸 Photography Tips

  • Perch shots: Identify a regularly used perch and position yourself below it for upward shots. The bird will return within 30–60 seconds of a successful hunt.
  • Background: Blue sky backgrounds for perch shots can work well with backlit plumage. Reed or foliage backgrounds give more natural images.
  • Colony: Early morning at the colony gives the most activity — pairs returning to burrows, chicks calling at the entrance, aerial hunting above the bank.
  • Lens: 400–500mm for perch shots. 500mm+ for flight shots.
  • Flight shots: Bee-eaters fly in predictable patterns between the colony bank and hunting territory. Pre-focus on a known flight line and use continuous AF.

See It With Expert Guides

European Bee-eater colonies are visited on the Caraorman excursion (Day 2–3 of both cruise programmes). Pre-migratory August gatherings are one of the delta's most spectacular late-season sights.
