8o4 PATAGONIAN EXPEDITIONS: ZOOLOGY. 



abundant where cover is thick, and occurs largely in the forests, where it 

 searches for minute insects just in the same manner as the Tits do in 

 Europe. 



"It is generally arboreal, though it often traverses the shrubs very low 

 down, and will descend to the ground to examine roots, fallen timber, etc. 



" Except when breeding, these birds keep in troops, and in this respect 

 as well as their call-note they are extremely like the Tits, for which they 

 might be mistaken by a person only knowing the former and not seeing 

 them close. 



"So far as I could see, they are strictly insectivorous. 



"They utter a rather loud chattering note and make some other sounds, 

 but none that could properly be called a song. When feeding in com- 

 pany they utter a call-note like that of the Coal-Tit." (Ibis, pp. 32-33, 

 1897.) 



Anairetes parulus patagonicus (Hellmayr). 



Spizitornis pandits patagoiiicus Hellmayr, Archiv. naturg. 1920, 85, p. 51 

 (Neuquen, Argentina). 



This race is described as differing from \x\x^ parulus '\xi having the belly 

 white and two light wing bars instead of one, but the Princeton Expedi- 

 tion series is difficult to separate on these grounds and leaves one in 

 doubt as to the true relationship of the forms. 



Three from Punta Arenas are all strongly yellow below with a single 

 wing band very faintly indicated. One from Coy Inlet is much whiter 

 with a faint yellow tinge on the abdomen only and with two well-defined 

 wing bars. Then there are two from "Chebunco, Patagonia," one of 

 which matches the Punta Arenas series while the other is slightly whiter 

 below and has two wing bars.
