5. Contopus richardsonii —Western Wood Pewee. 
I took an adult female on May 20, and an adult male on May 
23. The former was shot from its perch on a fence wire, from 
which it was making- frequent sallies after flies. The latter spec¬ 
imen was flying along the beach in front of camp early in the 
morning and lit on a ledge of rock. Both were undoubtedly 
migrants. 
6. Otocoris alpestris strigata —Streaked Horned Lark. 
The most abundant bird of San Nicolas Island; numerous every¬ 
where, but especially on the grassy mesa at the summit of the 
island. At the time of our visit the nesting season seemed to 
have just begun. On May 24, however, a brood of juveniles 
were noted, but these were the only ones seen. Mr. Gaylord 
found a nest on May 26. It was on the ground in a depression 
and consisted of an unusually generous lining of dry grass-blades 
and stems. The set of three eggs were considerably incubated. 
They are indistinguishable from eggs of the Mexican Horned 
Lark, and measure, .86X.65, .79X.63, .86X.63. Another set of 
three eggs was found by a member of our party, but on revisit¬ 
ing the vicinity it could not be located Forty-six skins of the 
Horned Lark were taken from this island. One of the speci¬ 
mens is remarkably deformed. The upper mandible is normal, 
but the lower manible is three-fourths of an inch long, and 
curved like the bill of a California Thrasher. It would be puz¬ 
zling to decide how the bird could manage to pick up anything. 
7. Corvus corax sinuatus —American Raven. 
Common. One specimen taken. 
8. Carpodacus mexicanusfrontalis —House Finch. 
Only about twenty were seen during our stay on the island, so 
this bird is by no means common. Fully-fledged juveniles were 
noted, and a nest found May 25. It was in a hole in the sand¬ 
stone bluff above the beach but could not be reached. The 
female was seen to leave it on several occasions. Four speci¬ 
mens of the House Finch were taken. 
9. Salpinctes obsoletus —Rock Wren. 
Very common over the whole island, but especially along the 
banks of the dry water courses. Juveniles, from stubby-tailed 
fellows just out of the nest, to full-grown ones were more num¬ 
erous than the adults. The latter were very shy and hard to
