"Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it.” — Samuel Johnson (1775)

We have endeavoured to make as much information about the birds available in one place - both formal peer-reviewed articles and reports and popular media including newspaper and magazine articles. Please feel free to browse through the titles in the list below and where possible we have made a pdf or web link available. Please help us keep this up-to-date with any other article you know of that we may have left off or that are new. We are in the process of making this searchable too.


Being updated all the time, so if you know of a link we missing, please forward it on to us.
