South-East Asia is currently facing an avian extinction crisis driven by a huge volume of domestic and international trade in wild birds (Nijman, 2010; Eaton et al., 2015). Indonesia in particular, is considered a central hub for trade, typified by recent evidence demonstrating how domestic trade is driving major population declines in wild birds in Sumatra (Harris et al., 2016). This PhD project aims to understand the characteristics of demand for songbirds, and using this information to investigate and identify measures that will reduce the impact on wild bird populations and improve sustainability of the industry.

Over 3,000 face-to-face interviews have been conducted right across Java - gathering data on the bird-keeping habits of respondents, alongside their perceptions and beliefs relating to bird-keeping, such as how many, and what types of birds they own, why they keep birds, and whether they see a connection between their birds and wild populations. The surveys have been by a team of students from Indonesia and Harry Marshall. Study sites were chosen to capture an equal share of urban and rural settings within each administrative region in Java. Previous work on this topic has mainly focused on urban populations of bird-keepers, however by including rural localities we hope to uncover a more nuanced understanding of demand across Java.

Another dimension to the situation is that as the sale of birds in markets appears to have decreased in recent years (in part thanks to work by NGOs exposing illegal trade), and it is now becoming easier to buy wildlife on the internet. Trade now happens over social media, which isn’t surprising considering Indonesia has one of the fastest growing social media markets, and has the fourth highest number of Facebook users globally. An online version of the survey will therefore be made available and shared at singing contests, at universities, and via social media links to allow access to a much larger audience. Another important part of the project is using web-scraping to gather information on the habits, perceptions and beliefs of hobbyists, and subsequently using text-mining analytics to determine what key factors influence a bird’s popularity, and what species may become threatened in the future. The results from these online-based techniques will be compared with the results from the face-to-face survey to determine whether they represent a cost-effective means for collecting crucial data on bird-keeping in Indonesia.
