REPORT ON THE MIGRATION OF BIRDS. 



From Iceland a rejjort has appeared (1886 ; Orw/.s-, ii, Grondal), wlierein 

 28 species are designated. 



Giitke lias published three auniial reports on the migration of birds 

 on the island of Heligoland, in the form of continued diciry-notes (Jan- 

 uary, 1884 — December, 1880) on the weather and on the observed species 

 ( Onws, i-iii). Furthermore R. Blasius published (riitke's work "Die 

 Vogelwarte He]ig<dand", wherein are i)reserved the results of fifty- 

 three years' observations of the circumstances of the migration of the 

 birds on this remarkable migration station {Ornis, yii, p. 132). 



Some reports appeared on the migration of birds in Holland : 



Dubois also published the following reports from Belgium:

Three numbers of communications of the ornithological commit- 

 tee of the Iloyal Swedish Academy of S(!iences, })iepared by Sundstrom 

 and Smitt, contain the observations made l)y 107 correspondents in 

 Sweden during recent years up to 1886. 



From the Russian Baltic provinces, especially Livonia, E. von ^lid- 

 dendorff has sent three annual reports, 188r)-'87 [Oniis). 



Abstracts of the pheuological observations made in Finland have 

 been published by Ad. Moberg {Ofv. Finslca Yet. Soc. Fiirh.) for a num- 

 ber of years; and in the years 1878-'80, arrival data in tabular form 

 for 12 species of birds at 31-68 stations have been published. The re- 

 mainder is still being pre])ared for publication; also a cxunpreheusive 

 materia] of observations which were sent to the writer in reply to a 

 summons of the year 1885. Out of this material, oidy a few local 

 faunas have been published by way of ])reliminary. 



We may here remark that in most of the other countries of Europe 

 and in some isolated states out of Enrope, it has been resolved in prin- 

 ciple to join the above mentioned effiu-ts, and some observations are at 

 hand ready for printing, while in others the way has been prepared 

 for this accession only by a few calls to the friends of the birds. 



The investigations on the migration of birds in Great Britain have, 

 as is known, taken a form consonant with the insular character of the 

 territory. At the instance of the British Ornithologists' Union and with 

 co-operation of the Britisli Association for the advancement of Science, 

 observations were commenced at most of the British light-houses and
