Some notes from various sources, indicated in each 

 case, have been added by the Compiler. 



In the last Report were stated the preliminary results 

 of the endeavours of Prof. Lütken to utilize the opportuni- 

 ties for observations on birds afforded by lighthouses and 

 light-vessels. In 1886 it was ordered by the Government, 

 that birds killed on striking the lights should be sent to 

 the Zoological Museum of Kjöbenhavn (in some cases only 

 samples, in other only parts of the birds), date and weather 

 being noted; the necessary means for postage etc. were 

 granted. Lightkeepers were also asked for such other in- 

 formation on birds as they might be able to give. The 

 scheme began to work on May ist. 



Clear nights being very common during the time of 

 passage not very many birds came to the lights. From 

 24 stations (out of 63) were received 469 specimens (entire 

 or in parts) of Sy species (identified by the Compiler). — 

 On the morning of May i4th many birds had arrived at 

 Kjöbenhavn, both fresh species and fresh individuals of 

 others; late in the previous evening 1 heard Actitis hj'po- 

 leucus passing overhead; the night was dark and rainy, with 

 a strong easterly wind. I therefore had expected something 

 from the lights; but only a few birds were sent or noted, 

 the night being however one of the very few in May when 

 any birds Struck the lights. — In autumn by far the most 

 birds came to the lights in two periods, the first being 

 September 3oth to October 2d, the next October i8th to 

 25th, more especially 2ist to 24th. There was a marked 

 movement of a few species at the close of December. 



A feature of the year was the exceptionally long and 

 continuous (though not very hard) frost, with considerable 

 snow, lasting to about March 20th and greatly delaying 

 the arrival of the earliest migrants. On March 2 ist thaw 

 set in at Kjöbenhavn, but no real passage was feit tili 24th, 

 when it was very marked. The species that habitually come 

 near this date or a liule later were not at all delayed.
