154 TRINIDAD AND TOBAGO BULLETIN. [XX. 2, 36-4. 



The recorded species are given below. The ten species marked 

 with an asterisk I have seen myself at various dates between 1918 

 and 1921.

Leotaud, {Oiseaux de lisle de Trinidad, 1860) describes fifteen 

 of these species and one other (the Saphir-Savan) which may possibly 

 refer to the Carib Emerald, but cannot be determined with certainty 

 from his description. 



Chapman in 1894 notes ten species and remarks on the habits of 

 several of these . {Bull. Amer. Museum Nat. Hist. VI 1 894 pp. 1 -86). 



Hellmayr in his collection from Trinidad described in Nooitat 

 Zool. XIII (1906) had fifteen species represented, the missing ones 

 being the Amethyst and Lesson's Emerald. 



In spite of a general supposition that humming-!: irds sip the 

 nectar from flowers, they are in reality almost exclusively nsect 

 eaters which will be seen from the notes given below and which has 

 been found elsewhere by other observers. They visit flowers almost 

 entirely for the purpose of getting the small insects which are 

 found therein. 



The nests of humming-birds fall into two very distinct groups. 

 First the " saddle " nests, which are attached to a branch or a fork 

 of a branch in such a way that the opening of the nest is pratically 

 always above the level of the branch which passes through it. A 

 typical example of this is seen in Plate III fig. 6.
