Mr. H. Durnford^s Notes on the 
^SyCALIS LUTEOLAf. 
Common throughout our journey in the valleys. They 
congregate in the winter in large flocks^ and^ I believe, are 
then partially migratory. 
.-4- ^Molothrus bonariensis. 
A few occasionally observed at Chupat, but not seen during 
our journey to Lake Colguape. 
Iris wood-brown; beak, legs, and feet black. 
*Agel^us thilius. 
Resident. Seen commonly throughout our journey where- 
ever there were any reed-beds. 
*Sturnella militaris. 
Resident. Common throughout our journey. .Of all birds 
(of course excepting water-birds and reed-loving birds) this 
is the surest indicator of the presence of water in the thirsty 
plains of Patagonia, never being found far from this element, 
and being consequently of great use to travellers. 
Beak dark horn-colour, under mandible lightest; legs pale 
grey; feet and claws darker. 
AgRIORNIS MARITIMUS. 
I shot one at Tombo Point 31st December, 1877, but did 
not see any other specimens. 
Myiotheretes rueiventris. 
A few visit Chupat in the spring, remaining till the end of 
the summer j and I observed them occasionally throughout 
our journey. They often consort with Oreophilus ruficollis. 
Iris light brown; beak, legs, feet, and claws black. 
^T^nioptera rubetra. 
Observed at Chupat in September, but rarely. Common 
in the valley of the Sengel in November. ^ 
Iris light fulvous; beak, legs, feet, and claws black. f 
*Lichenops perspicillatus. 
Resident and common everywhere throughout our journey. I
