![]() ![]() House sparrows use a broad range of materials for nest building, including feathers, grass inflorescences, stalks and roots of plants, barks, threads, strings, and pieces of paper and wool ( Indykiewicz 1990). The species mainly nests in holes and crevices of man-made structures and nest-boxes ( Summers-Smith 1988). ![]() This multi-brooded species is widely distributed in cities and are known to build open-cup nests which may be reused during the same season as well as in successive breeding seasons ( Cavitt et al. Nest building is most intense during January to May ( Vincent 2005). ![]() House sparrows generally build single or semi-colonial nests. One of the reasons predicted to be the cause for their decline is lack of nesting sites. 2002 Royal Society for the Protection of Birds 2003 Vincent 2005 Anderson 2006 Dhanya 2012). The decline of the species is being recorded from different parts of the world ( Hole et al. House sparrows are closely associated with human dominated landscapes ( Summers-Smith 1988). Kajian ini telah menunjukkan perhubungan antara penggunaan bahan untuk membina sarang sepanjang gradien kawasan bandar ke luar bandar, untuk burung yang berkaitan rapat dengan manusia. Satu pengurangan beransur penggunaan bahan tumbuhan mengarah ke kawasan bandar telah dikenal pasti ( p<0.05). Penggunaan bahan antropogenik tinggi di kawasan bandar ( p0.05). Bilangan bahan antropogenik berbeza mengikut gradien kawasan. Dalam kajian ini, kami telah mengenal pasti 11 spesies tumbuhan, 2 jenis bahan haiwan, dan 6 jenis bahan antropogenik, termasuk kepingan plastik dan tali halus. Sarang-sarang tersebut mempunyai 2 lapisan jelas, iaitu lapisan struktural dan lapisan dalaman. Daripada 30 sarang yang diperhatikan, 15 merupakan dari kawasan luar bandar, 8 daripada kawasan subbandar, dan 7 dari kawasan bandar. Untuk kajian ini, kami telah memilih jalan Coimbatore ke Anaikatty (State Highway-164), satu jalan lebuh raya 27 km panjang, yang melalui satu kawasan bandar ke luar bandar di Coimbatore. Di sini, kami menerangkan tentang bahan-bahan yang digunakan oleh burung ciak rumah untuk membina sarang sepanjang gradien kawasan bandar ke luar bandar. Spesies ini mempunyai perhubungan yang dekat dengan manusia, maka ia bersarang atas struktur-struktur buatan manusia. This study explicitly documents the links between nest material usage along an urban to rural gradient, in a human associated bird.īurung ciak rumah ( Passer domesticus) merupakan spesies burung yang tersebar luas di seluruh dunia. A gradual decrease in the usage of plant matter towards the urban area was noticed ( p<0.05). The usage of anthropogenic materials was high in urban areas ( p0.05). The amount of anthropogenic materials in the nest formation varied along the gradients. In the current study, we identified 11 plant species, 2 types of animal matter, and 6 types of anthropogenic matter, including plastic pieces and fine rope. The nests had two distinct layers, specifically the structural layer and the inner lining. Of the 30 nests observed, 15 nests were from the rural, 8 were from the suburban, and 7 were from the urban areas. For the current study, we selected the Coimbatore to Anaikatty road (State Highway-164), a 27 km inter-state highway, which traverses along an urban core to rural outstretch of Coimbatore. Here we describe the materials used by the house sparrow for making nests along an urban to rural gradient. Being a species which has close association with humans, they chiefly nest on man-made structures. The house sparrow ( Passer domesticus) is a widely distributed bird species found throughout the world. ![]()
