Excerpt from The Migration of British Birds: Including Their Post-Glacial Emigrations as Traced by the Application of a New Law of Disperal Being a Contribution to the Study of Migration, Geographical Distribution, and Insular Faunas The present volume is the result of much additional thought and hard work generally upon the subject of Avian Emigration and Migration. It is a subject that has a peculiar fascination for me, doubtless because it offers all the charm of novelty, and is as yet a practically unworked field of research. No branch of Ornithology can possibly be more interesting than that which treats of the Dispersal - either by Emigration or Migration - of Birds over the globe. To many naturalists this dispersal may appear entirely fortuitous, or very largely due to such abnormal influences as Glacial Epochs. I honestly confess that for many years I was imbued with very similar ideas what all men accepted as true must assuredly have been truth. But after a long and careful study of the phenomenon of Emigration (or Range Extension) I began to doubt some of the most generally accepted views respecting the Geographical Distribution of Species. Difficulty after difficulty arose, convincing me more and more that the solution of the problem must be sought in other directions.
