The Swirl Swirl ( Locustella lanceolata ) is a songbird belonging to the grass warbler family (Locustellidae). There are two subspecies.
The Strichelschwirl, which occurs from north-east Europe to Japan, is a very rare errant in Central Europe . Between 1988 and 2002 individuals of this species were observed five times in Belgium and once each in the Netherlands and on Heligoland .
features
The 11.5–12.5 cm long Strichelschwirl is a short-necked and short-tailed bird with matt brown plumage, which is striped black on the top and dashed black on the underside. Males and females are colored the same.
distribution and habitat
The breeding area extends from northeast Europe over the north Asian taiga to the Japanese island of Hokkaidō . The nominate form Locustella lanceolata lanceolata occurs from northeastern Europe to Kamchatka . The subspecies L. l. hendersoni is common from Sakhalin to Japan. The Strichelschwirl is a long-distance migrant whose main wintering quarters extend in Southeast Asia to the west of Java and Bangladesh . Breeding birds of Western Siberia initially migrate 5,000 kilometers eastwards and then migrate another 4,000 to 6,000 kilometers south via eastern China. The move to the wintering quarters begins in mid-August. They return to Western Siberia in the period from mid-May to early June. The European breeding bird population is estimated at 50,000 to 100,000 breeding pairs. That should make up a little less than five percent of the world's population.
The swirling swirl lives in dense bush and grassland near the water. More often than the striped swirl , it can also be found in dry terrain. In their wintering quarters, they can often be seen in rice fields.
behavior
This insect eater hides in the grass and deep foliage. Five eggs are incubated in a nest in a tuft of grass.
