The Little Bittern (Ixobrychus minutus) is a discreet and well-camouflaged bird, difficult to spot in the dense vegetation of wetlands. The smallest of the herons, this bird is known for its characteristic posture: when it feels threatened, it stretches vertically, aligning itself with the reeds to blend perfectly into its surroundings. It moves stealthily among the reed stems and is most active at dawn and dusk.

Distribution in Romania
This species is common in Romania’s wetlands, especially in the Danube Delta, river floodplains, and lakes with abundant vegetation. It arrives in spring and departs in autumn, being observable from April to September.
Behavior
The Little Bittern is solitary or lives in pairs. It is a nocturnal or crepuscular hunter, feeding on small fish, amphibians, aquatic insects, and crustaceans. It nests in reeds, building a small nest from dry vegetation, where the female lays 4-6 eggs, incubated by both parents for about 17-19 days.
Conservation Status and Threats
Although classified as a species of Least Concern, its population is vulnerable to habitat destruction due to wetland drainage, pollution, and climate change. Protecting reed beds is essential for maintaining its population.
Where Can It Be Observed?
The Little Bittern can be seen in the Danube Delta, lakes in Călărași, Brăila, Balta Mică a Brăilei and other wetlands rich in aquatic vegetation.
Fun Facts
When threatened, it adopts a “camouflage” posture, aligning perfectly with the reeds.
It can fly swiftly through dense vegetation.
Its calls are soft and difficult to hear, resembling a “bup” sound.
Chicks grow quickly and become independent at around three weeks old.
Conclusion
The Little Bittern is a fascinating bird, well adapted to life in wetlands. Though difficult to spot, with a bit of patience and a pair of binoculars, nature enthusiasts can enjoy a memorable encounter with this small heron.
