Lesser whitethroat

The Lesser whitethroat is a migratory species, arriving in the Danube Delta in spring and departing for wintering regions in North Africa and the Middle East in autumn. During the nesting season, they are extremely territorial. They build well camouflaged nests in bushes, where females lay an average of 4-6 eggs. Both sexes raise and feed the young. Outside the nesting season they become more sociable and can be seen in small groups.

Description and how to observe Lesser whitethroat:

The Lesser whitethroat is a small bird, about 12-14 cm long. Its plumage is predominantly grey, with a lighter abdomen and a pronounced dark mask on the face, making it relatively easy to identify by contrast. The eyes are emphasised by a whitish ring. It is best seen in spring and summer, when males are most active and display their trills to mark their territory. Common in areas with shrubs and dense vegetation.

What it feeds on Lesser whitethroat:

The diet of the Lesser whitethroat is predominantly insectivorous, consuming insects and larvae, which helps to control insect populations in the habitat. Outside the breeding season, their diet expands to include berries and seeds, adapting to available resources even in colder periods.

Threats:

Although not considered a globally threatened species, the Lesser whitethroat is facing various local threats in the Danube Delta, such as loss of natural habitats due to expanding urbanisation, intensive agriculture and pesticide use. Climate change is also influencing migration patterns and food availability.

Ecological role:

The Lesser whitethroat has a significant ecological role in controlling insect populations, which helps maintain the ecological balance of the Danube Delta. In addition, by eating the fruit, it facilitates seed dispersal, contributing to vegetation regeneration and habitat biodiversity.
