As I am, in a measure, godfather to this Edition of Mr. Gatke's Observations on the avifauna of Heligoland, it becomes a real pleasure to me to draw the attention of English-reading ornithologists to the true value and worth of the author's work. He has studied the subject of Migration of Birds and Bird-Life at all seasons at his great observatory, with little cessation or interruption, day after day, and night after night, for the last fifty years: and I consider that the unstinted gratitude of all fellow-workers in the same field is due to him for adding such a luminous and important contribution to our knowledge of the ways of Birds.The plan of Mr. Gätke's work is excellent, and at once stamps it as representative of good work done both in the field and in the study. He tells us, and we can realise the fact, that Heligoland stands pre-eminent as an ornithological observatory in the west of Europe. It is the key, as it were, to the situation, so far as ascertained by these fifty years of observation and experience; and as such is expounded in the present volume.
