If you are interested in the pattern of bird migration in Ireland and Britain you may like to visit the BTO/BirdWatch Ireland Migration Site.
Phenology is the study of the dates of recurring natural phenomena such as the arrival and departure dates of migratory birds and the dates of bud break and flowering of plants and trees. It is thought that this type of study may be of particular relevance to Global Warming and other climatic phenomena.
The Irish Native Woodland Trust web site has a page via which you can contribute to this study.
