form, these being the first recorded from Hispaniola. Two were 

 taken at Fort Liberte February 8 and 11, and three at En Cafe on 

 Gonave Island March 5, 6, and 7. One from Fort Liberte and two 

 from Gonave are young birds with the black feathers of the facial 

 mask just appearing. From examination of these it seems that the 

 black comes in first on the cheeks and from there extends across the 

 crown. 



This form of the yellowthroat has been reported from Cuba and 

 from various islands in the Bahamas so that it is to be expected to 

 range to Hispaniola. It is closely similar to the northern yellow- 

 throat, differing only in less extent of yellow below, slightly less 

 greenish upper surface, and slightly smaller size. It may be dis- 

 tinguished only by careful study of specimens in the hand.

Winter visitant; common. 



The yellow-throat 1 is found in numbers at the proper season in 

 weed-grown fields, and the borders of marshes in the lowlands, and 

 also ranges widely into the higher altitudes where there is suitable 

 cover for it. It lives near the ground concealed in the dense growths 

 that it affects, coming out on open perches for a few seconds and 

 then dodging back quickly out of sight, or flushing with tilting 

 flight to fly for a few yards before disappearing again into its 

 coverts. Attention often is directed to it by its harsh call note, a 

 low chimp, as it scolds whenever disturbed.
