Acrocephalus arundinaceus Detailed Introduction

The Great Reed Warbler is a small bird, commonly known as the Great Reed Warbler, the Reed Casper and the Reed Grasshopper. It is sexually active, often jumping and climbing between grass stems, reeds and bushes alone or in pairs. It is extremely alert, changing its position from time to time and suddenly appearing in another place. During the breeding period, it often stands on the top of reeds or small branches near the nest to sing. Sometimes it stands on the branch and sings continuously for a long time, sometimes it changes its position to sing, or moves for a while, sings for a while, or moves while singing. The call is loud, harsh and incoherent, with a heavy guttural sound, mixed with sharp and high calls and low croaks. The call includes a harsh "tack" and a squeaking "churr".

The breeding season of the Great Reed Warbler is from May to July. During the breeding season, it makes a noisy "quack" sound. It builds its nest in reeds and bushes, fixed on a bunch of plants or reed stems 0.5-1.2 meters above the water surface (or the ground). The nest is cup-shaped and is mainly woven from reed leaves, dead grass stems, grass leaves, flower stalks, plant fibers and spider webs. The inside is padded with dry grass leaves, thin grass stems, fibrous roots, etc., and sometimes feathers. The female bird is mainly responsible for nesting, and the male bird often accompanies the female bird in transporting nesting materials. The size of the nest is: 9-14 cm in outer diameter, 5-9 cm in inner diameter, 27 cm in height, and 6-7.5 cm in depth. Each nest lays 3-6 eggs, which are green-white or blue-green, with brown or olive brown spots and black-gray or gray spots. The size of the egg is 21-25 mm × 15-17 mm. The female bird is responsible for incubation, and the incubation period is 14-15 days; the chicks stay in the nest for about 12 days.
