Expedition to Tucuman and Salta. 423 
about fifteen miles, and stopped for the night at Lo Noyalitos, 
a collection of huts in open camp-land. 
The scenery is more beautiful after leaving Rosario, and 
the road finds its way over many little hills and valleys. 
Hawk, one shot; only one seen. 
Buenos-Ayres White Falcon (Elanus leucurus), black wings ; 
a few seen on open lands. 
Patagonian Falcon (Circus cinereus), the common kind; 
female brown, male white; a good many seen. 
June 12. Started early from our rancho of last night, and 
did about eighteen miles, stopping the night at Rio de las 
Piedras. Scenery lovely, the low Sierras dotted with trees 
to theirsummits. The weather is more favourable, and today 
has been very warm, the thermometer at 8 p.m. marking 71°. 
Scenery continues lovely ; the birds as yet do not, however, 
differ much from those seen near Tucuman. I intend stop- 
ping here tomorrow to rest the mules, and in three or four 
days afterwards I hope to be in Campo Santo and call on 
Sr. Cornejo. 
This (Rio de las Piedras) , I think, would be a good spot for a 
collector. The woods axe large and thick, and the river 
always well supplied with water. Scenery improves still 
more as we advance. Synallaxis?, one shot, three seen, 
male, frequenting low scrub in open spots. 
June 18. Remained all day at a rancho close to Rio de las 
Piedras, where I slept all night. Shot a few birds. 
Limnornis common in the low bushes ; it has a loud jarring 
note, like L. curvirostris, and hides continually in the low 
bushes; one shot. 
Minute Woodpecker, one shot, only one seen ; habits similar 
to others of this genus, but frequents smaller trees. 
Small Flycatcher, common, one shot. I believe same as 
that shot on the 8th, but I am not certain. 
Pigeon, one shot, very common, frequents pretty low trees, 
seen everywhere ; sometimes raise long feathers on head. 
One other bird shot and skinned. 
Junel4, Started at 9 this morning on my journey; about 
6 arrived at the Rio Pasaje, the largest I have yet seen.
