IMMIGRATION OF SUMMER BIRDS*

Under the heading of " Stray Notes," on page 198 of Vol. IV.

N.S. 1906, we referred to the first Report issued by the Committee

appointed by the British Ornithologists' Club to collect evidence

regarding the immigration of summer migrants. This was very

instructive and valuable, bnt it will be at once recognised that

the results of one year's observations are entirely inadequate to

elucidate the complex problems presented by this phenomenon.

The combined results of several years observations are necessary

before any definite results can be obtained, and hence it is in-

tended to carry on these observations for several years.


The Second Report is now published, and deals with the

immigration of the Spring of 1906. The number of observers

has been largely increased, but more are still required as a few

districts are still unrepresented. The Report is a valuable record

and reflects great credit on the observers and especially the

Migration Committee of the British Ornithologists' Club. Those

who are interested in the subject of Bird Migration should not

fail to possess themselves of it as well as the previous Report

issued last year.
