Baya Weaver Count (10 to 24 June 2018) Organized by BNHS

Weavers are highly social birds; these species are very similar to House Sparrows Passer domesticus and these are known and famous for their nest-weaving skills. Four species of weavers, belonging to family Ploceidae, are resident in India, these are, Baya Weaver Ploceus philippinus, Streaked Weaver Ploceus manyar, Black-breasted Weaver or Black-throated Weaver Ploceus benghalensis and Finn's Weaver or Yellow Weaver Ploceus megarhynchus.


Among the four species of weaver birds, Baya Weaver Ploceus philippinus  is the most familiar and common bird in the country. This species builds overhanging nests built in colonies, usually above water or in a well. It’s food includes grains, seeds, and small insects. The breeding season ranges between April to August. The male weaver appears yellow in breeding plumage, male builds their retort-shaped nests in colonies, they continuously sing during nest building. The Baya Weaver has a polygamous breeding system means one male builds multiple nests and mates with many females (not necessarily at the same time). Urbanisation, agricultural practices, industrialization, development, human population, deforestation are the major threats to this species.


All Indian Weaver species are protected and listed in Schedule IV of the Wildlife (Protection) Act, 1972.


Objectives of Baya weaver count


1) To gather information on year-to-year and longer-term changes in population levels for a wide range of Baya Weaver across different habitats across India.

2) To understand whether the population trends.

3) To promote bird conservation through the involvement of a large number of volunteer observers in survey work.

4) To collect the data, ideally every year during breeding season of Baya Weavers, so that in the long run we can get information about the changes in the population of the Baya Weavers.
