LITTLE WIDOW TYRANT 145 



Mr. Barrows observed them in autumn on the 

 Pigue (southern pampas) preparing for their migra-

 toward evening, and went through a series of aerial 

 evolutions accompanied with vocal exercises of a 

 varied and entertaining kind, lasting half an hour 



or more.

LITTLE WIDOW TYRANT 



Tsenioptera irupero 



Above and beneath pure white ; wings with the primaries black 

 except the innermost, which are white at their bases and tipped 

 with black, and secondaries which have narrow black shafts ; broad 

 end of the tail black ; bill and feet black ; two outer primaries 

 acuminated ; length 7 inches. Female similar. 



THIS pretty species is found throughout the Argen- 

 tine country, and is well known to the natives, and 

 usually called Viudita (Little Widow) on account of 

 its mourning colours. It is also sometimes curiously

 notion due to the intense whiteness of its plu- 

 mage and to its supposed habit of frequenting 

 graveyards.
