had accidentally wandered from the islands, or a case of unusual variation of 
actia. 
D. R. Dickey, L. M. Huey and I found horned larks most abundant on the 
open uplands of the northwest end of San Clemente in the spring of 1915. 
Young on the wing were noted March 25; and during the first week in April see- 
ond sets were being laid with remarkable uniformity. A number of nests were 
found, containing either two or three eggs. They were located at the edge of the 
ice plants, or in the lee of a wisp of grass. 
J. Grinnell (8) says that it was the commonest species on San Nicolas, but 
that (ZS) on Catalina horned larks were decidedly rare except at the northwest 
end. Here he heard them on the hillsides near Johnson’s Harbor, August 27, 
1903; G. Willett (ZS) saw them occasionally on this part of the island during 
March, 1905. On Santa Barbara Island the larks are everywhere under one’s 
feet. A nest which I discovered May 1, 1910, held a single egg and was of the 
usual construction, flimsily built of dry grass only. H. C. Burt (35) reports the 
species as common on Anacapa. 
A number of observers have found it in numbers on the more exposed por- 
tions of Santa Cruz Island, but it is inclined to be local here, for in the vicinity 
of Prisoner’s Harbor in the spring of 1911, A. van Rossem and I made a very 
diligent search for it without results. H. W. Henshaw (11) found a nest here, 
placed in one of a large pile of abalone shells, overgrown with herbage. He said 
that horned larks occurred in flocks of both sexes all through June. 
G. Willett (34) found this to be one of the commonest land birds on San Mig- 
uel. They had evidently raised one brood and were starting to nest again the mid- 
dle of June, 1910. Here, on June 21 of the same year, O. W. Howard (23) collect- 
ed a set of three eggs, in which incubation had begun. Several have reported the 
species from Santa Rosa, but it does not seem to be especially abundant there. 
Eggs are indistinguishable from those of actia. From the above dates I judge 
that this subspecies must raise at least three broods a season.
