PHOWN (PHotos Of Weaver Nests) is a monitoring project aimed at determining the distribution of colonies or nests of all weaver species globally. Counting weaver nests and taking photos allows tracking of changes in weaver breeding effort. Many weavers are common and this project provides an easy way of monitoring them, while some weaver species are threatened and this project would help their conservation. The software for the ADU Virtual Museum projects was written by Rene Navarro and the current software allows users to submit photos directly to the web, rather than emailing photos. PHOWN is the fourth Virtual Museum project and was launched in time for the 2010 breeding season. In the Western Cape Southern Masked and Cape Weavers had started to build nests.
