452 Dr. E. Lonnberg on Birds from 



35. Piirygilus plebeius Cab. 



Iris brown. This was the most common bird at Moreno. 

 It resembles the European House-Sparrow in its habits. It 

 builds its nest in crevices in the rocks, but also under the 

 roof-tiles of houses and in bushes. The eggs are said by 

 Mr. von Hofsten to be white, measuring 22 mm. in length 

 by 15 mm. in breadth. Usually there are three or four in 

 a nest. The food of the bird consists of seeds, buds, and 

 caterpillars. 



IV. Birds of San Luis, near Tarija, in Bolivia. 



The third Station of the Swedish Expedition was near 

 Tarija, at a place named San Luis. In its surroundings 

 it resembled the second as regards the natural conditions, 

 but it was not so high above the sea as Moreno, and, 

 although "puna" prevailed round Tarija as well, there was 

 a richer vegetation, which made a change for the better. 

 The bird-life was almost entirely different from that of 

 Moreno, and decidedly richer. 



The following birds were collected at the third Station and 

 during excursions around the same. 



1. Nothura boliviana Salvadori. 



The specimen from San Luis which I refer to this species 

 (iris brown) has no markings on the inner webs of the three 

 outer primaries. Wing 125 mm., tarsus 29 mm. It was 

 shot in January 1902, and eggs taken on January lGth 

 probably belong to this species, as no other member of the 

 family was procured. They were laid in a shallow nest lined 

 with twigs, straws, and feathers of the bird. They were 

 four in number and measured from 43 to 45 mm. in length 

 to 32*5 mm. in thickness. They have the usual enamelled 

 or china-like surface and are in some lights greyish with 

 a plum-coloured tinge, in others brownish with a tinge of 

 chocolate. 



2. Columbula picui (Temm.). 



One specimen, shot at San Luis, January 27th, 1902. 

 Iris lilac.
