BIRDS OF NAVASSA ISLAND 



Finally there may be listed the few birds known from distant 

 Navassa, an American possession that is included in the present ac- 

 count through its geographic position. Our present knowledge of 

 the life of this island comes principally from the work of R. H. 

 Beck who was there in July, 1917, and Dr. E. L. Ekman who visited 

 Navassa in October, 1928. The list at present contains twenty-one 

 forms, one peculiar to the island and two of doubtful status : 



Sula leucogastra leucogastra 

 " piscator 



Fregata magnificens 



Falco peregrinus anatum 



Sterna anaetheta melanoptera 



Golu-niba leucocephala 



Coluniba squamosa 



CJutemepelim passerina navassae 



Coccyzus americanus americanus 



Crotophaga ani 



fTyto glaucops 



Megaceryle alcyon alcyon 



Tyr annus dominicensis dominicensis 



fPetrochelidon fulva fulva 



Vireo olivaceus olivaceus 



Mniotilta varia 



Dendroica palmarum palmarum 



Seiurus aurocapillus aurocapillus 



Geothlypis trichas orachidactyla 



Setophaga ruticilla 



RECOMMENDATIONS REGARDING FURTHER STUDIES 



Attempt has been made in the present paper to make the account 

 for each form complete so far as existing information permits but the 

 many gaps in our knowledge of many birds are readily evident on 

 careful perusal. There are needed especially definite observations on 

 the nests, eggs, and nesting habits of numerous forms, and an 

 economic study of the avifauna remains to be undertaken. The range 

 of the high mountain species remains to be worked out in detail, 

 and there is required much information regarding migrants that 

 come to the island with regard to their arrival, departure, and relative 

 abundance. In a word, the present account with its summary of 

 present information may be taken as a starting point for further 

 detailed studies. 



Finally, recommendation is made that definite areas in both re- 

 publics be set aside as national parks and established as sanctuaries
