Moustached warbler

Description

The Royal Warbler (Acrocephalus melanopogon) is a species of passerine bird in the family Acrocephalidae.It reproduces in southern Europe and in temperate zones of southern Asia and in a small portion of northwest Africa.It is partially migratory,in the southwest of Europe they are residents,in the south of Eastern Europe the birds winter in the breeding area of the Mediterranean,and the Asian subspecies migrates to Arabia and India.It is scarce in the north of its distribution,but there have been sightings in latitudes as far north as Poland and Denmark.There are some reports from Britain,including a couple who grew up in Cambridgeshire in 1946,but these records have recently been removed from the official list of British birds.This species is usually located among vertical aquatic vegetation,such as reeds and reeds.They deposit between 3 and 6 eggs from mid-April and incubate for 14-15 days.The nest is built on the water between the reeds or reeds,or in a bush on the shore.This species is usually monogamous.It is a medium-sized sylvy,12-13.5 cm long,slightly larger than the similar common warbler Acrocephalus schoenobaenus.The adult has a finely striped brown back and white underparts.The forehead is flat,with a prominent whitish eyebrow,gray ear covers,and the beak is sharp and pointed.The sexes are identical,as with most of the sylvidos,but the young birds are have more lists and marks on the chest.It is insectivorous and includes water snails in its diet.The trill is fast and similar to the warbler.His song is softer and more melodious than that of his relatives,and may remind him of the nightingale.Unlike the warbler,they do not sing in flight.
