Avian communities of Lundy 2008-2016

Nine years of citizen science data about avian abundance on Lundy are analysed for diversity and similarity. Diversity is relatively stable across the nine-year period, as is similarity in year-to-year comparisons, but there is approximately 30% dissimilarity between years. This appears to be caused by migrant and vagrant birds, and passerines predominate. We make comment on the nature of the data collected, its limitations and also suggest how to improve data collection. We see this as a first step, and it is our hope that this article will stimulate further analyses of existing data, and encourage current and future researchers to further develop data collection and analytic techniques to better understand Lundy’s ecology. Such activity will be of direct use to management and conservation efforts on the island but also of intrinsic scientific interest.
