I^O BoNHOTE, Migration at some Bahama Ltghl/ioitses. \ a"^ 



the 15th April and the 13th May were the richest in variety of 

 species, and on three of these occasions the wind was southeast. 

 On the 15th April, however, the night in which 17 different species 

 were procured, the wind was north-northwest. Although we 

 think it is well to draw attention to these facts, too much stress 

 should not be laid on the direction of the wind, as the number of 

 birds striking is probably far more dependent upon the state of 

 the atmosphere (/'. <?., rainy, misty, cloudy, etc.) than on the actual 

 direction of the wind. In the cases under consideration it will be 

 noticed that, with the exception of the 13th May, Mr. Thompson 

 records rain or mist in every instance ; it may be well also to 

 notice that the birds invariably come up to the light against the 

 wind and strike on the lee side of the antern. 



As regards species which were observed but of which no speci- 

 mens were sent, we notice Swallows on the 20th and 31st August ; 

 Kingfisher {Ceryle alcyon) 21st August and ist Sept.; Rice Birds 

 {Dolichofiyx) ist and 8th Sept., and Mr. Thompson estimates that 

 on the last mentioned date the flock consisted of at least 200 

 individuals. A Barn Owl also was seen on the ist September. 

 Flocks of small birds visited the island on the 4th and 9th Sept., 

 28th Oct. and 27th November. 



On the 20th April a large migration took place, the greater 

 bulk of which were small Passeres, but it also included Fighters 

 {Tyrannus) and Rice Birds {Dolichonyx). The last spring move- 

 ment recorded is on May 10, when a small flock of Passeres 

 rested on the Cay. 



There remains only for me to give my best thanks to Messrs, 

 Thompson and Solomon for all the trouble they have taken and 

 to hope that they may send us many more equally interesting 

 consignments.
