This data-set comprises validated species occurrence records of Weaver nests occurring in the continents of Africa and Asia, it includes all Weaver bird species. It is a collection of data from citizen science contributions, museum collections, and published literature records. Records range from 1779 to present.

PHOWN (PHOtos of Weaver Nests) is a citizen science monitoring project aimed at determining the distribution of colonies or nests of all weaver species globally, and studying the variation in their colony sizes. Counting weaver nests and taking photos allows tracking of changes in weaver breeding effort. This project provides an easy way of monitoring common weavers, while helping the conservation of threatened weavers.

Identification of citizen science records, based on the photos uploaded, is done by a panel of experts in the relevant taxa. The taxonomy is kept up-to-date by the project coordinator.

All data is available to the public. Records are provided at the recorded precision, usually point coordinates. The coverage is good for South Africa, moderate for Namibia, and it is very sparse for the rest of Africa and Asia.
