The striped swirl ( Locustella certhiola ) is a songbird from the genus of the swirl (Locustella) and the family of the grass warbler (Locustellidae). Several subspecies are distinguished.
Although its breeding grounds are thousands of kilometers away from Europe, the streaked swirl can be observed as a stray visitor in Europe, albeit very rarely. Observations from the last two decades of the 20th century have been made in Belgium, the Netherlands, Great Britain, Poland and Ireland.
description
The bird, measuring a good 13 centimeters, is reminiscent of the reed warbler in its plumage . The rump and upper tail feathers are rust-brown with a few dark dashes and clearly stand out from the gray-brown tail. The indistinct transverse banding of the tail widens to a dark end band. In the fresh plumage, an indistinct, bright end edge of the tail can be seen.
The under tail-coverts are yellow-brown in color, the back is striped and usually more brown than that of the Feldschwirl , the underside is greyish-white. Fledglings often show a yellowish tinge of the chest and sides of the body and a chest band made up of indistinct dark spots.
His singing begins sharply, which is followed by a short “rü-rü-rü”, which ends with a reed-warbler-like stanza. In winter quarters he calls "tschirr-trschirr".
distribution and habitat
The striped swirl lives in Siberia as well as Central and East Asia. He is a long-distance migrant whose winter quarters are in front and rear India. Occasionally it also winters on the Great Sunda Islands. The departure from Siberia begins in August and lasts until the end of September. The homecoming begins at the beginning of May. It arrives in its Siberian breeding areas in late May to early June.
The striped swirl behaves inconspicuously in the way of the swirls and inhabits damp, swampy meadows with tall grass and shrubbery. Even in winter it can be found in swampy places, for example in rice fields.
