10. Mirropus melanoleAieus. White-throated 

 Swift. A flock of about lift}' observed Jan. 

 r2th, and ai>ain on Jan. 21st. Mr. Bryant seems 

 to think tliey l)reed on the ishind. Two females 

 obtained. 



11. 7Vor/i(7«.s- (tnna^ Anna's lIiMinnin«jbird. 

 Three sju'eimens obtained. 



12. StiirncUd magnd najlprUi^ AVestei'ii Mead- 

 ow Lark. One bii'd observed. 



13. Carpodacus amplus^ Guadalnpe House 

 Finch. Large series obtained. Two nests 

 found in cypress trees Feb. 22nd. Set of five 

 egos Marcli 1st. Last nest taken April 7th, 

 with five eggs, containing small embryos. The 

 nest, was nearly always in the brancli of a cy- 

 press tree, but some were in tlie tops of i)alnis. 

 The most common height from the ground was 

 from ten to fifteen feet. Mr. Bryant thus de- 

 scribes the n(*sts and eggs : 



"The material used for the outer structme of 

 the nests consisted of the dark, dead stems of 

 weeds, only the finer ones being selected. One 

 nest found in a pine tree, had the foundation 

 and sides made of pine needles, with the invari- 

 able lining of goat's hair, black or white being 

 used indiscriminately. The external diameter 

 of the nest is al)out 130 nini., with a central 

 cavity of about (i") mm. "•The eggs, sometimes 

 four in number, butoftener five during the early 

 l)art of the season, are colored precisely like the 

 average specimens of C. frontalis rhodocolpus, 

 the sjjots being either sparingly applied or en- 

 tirely wanting. The}' also resemble them in 

 general sliap<', but the size serves to distinguish 

 them. The five eggs of set No. 792, measure 

 respectively 22 x 1") ; 22 x ]').'> ; 22 x 15.5 ; 23 x 

 15.5; 23x10.5 mm. Tlie length measurement 

 varies from 19.5-24 mm., and width 15-10.5 

 nun. The average of thirty-two specimens is 

 21.3 x 15.5 nun."' 



14. LoxAit ctirrirostru atrlctlnndi^ Mexican 

 Crossbill. Nine specimens obtained. 



15. Zonotrirltia coroiuUd, (iolden-crowned 

 Sparrow. Three females secui-ed. 



10. ,Sj)i."idhi tiorialits arlzowM^ Westei'ii Cliip- 

 ping Spairow. A single specimen, a male 

 taken. 



17. .Imiro lii/mi((lis orci/oinis, Oregon Juiico. 

 One specimen taken. 



18. JuHco insulariii, (Juadalupe Junco. Large 

 series collected. On March 10th Mr. Bryant 

 found a nest of this species, and on the 10th it 

 contained three eggs. It was in the cleft of a 

 pine tree, six feet from the ground, and was 

 composed "of a few i)ieces of bark-moss, light- 

 colored dry grass blades, and a tail feather of 

 a Petrel, all surrounding a quantity of grass 



blades, lined within with goat's hair. The 

 three eggs whidi the nest contained (set No. 

 797. Author's Oological Collection) were i)rob- 

 ably a second setting, the ragged appearance 

 of the female's plumage indiciiting previous 

 cares. In color the eggs are a i)ale greenish- 

 white, marked with fine dots of reddish-brown 

 clustered around the larger end. They measure 

 19.5x15; 10x15.5; 20x10 millimeters.^' 



19. Mdospiza linrohii., Lincoln's Sparrow. 

 One pair secured. 



20. Passcndl/i iliaca unaJasrhoisis^ Town- 

 send's Sparrow. One specimen taken. 



21. Pipilu roiisobrinus^ Giuadalu])e Towhee. 

 Large series secured. 



22. Ampidia rcdrnrinn, Cedar Wax wing. One 

 male taken. 



23. Lanins ludoviciannti ey.cuhUorldcs^ White 

 rumped Shrike. Two specimens secured. 



24. Dendroica auduboni, Audubon's Warl)ler. 

 Two males of this species were taken. 



25. Anthus pcnnsylvanicus, American Pipit. 

 One flock of about twenty-five seen, of which a 

 single specimen was secured. 



20. Oroscoptca montanus, Sage Tlu'asher. One 

 nude was shot. 



27. Mimiis jiol>/(/l(ittns, Mock'w^ l?ird. A sin- 

 gle specinu-n taken. 



28. Salpincees g^iadalotipeusiti, (Juadalupe 

 Rock Wren. The most abundant species on 

 the island, and a large series taken. Mr. Bry- 

 ant's notes concerning the nesting of this spe- 

 cies are very full. Some of tliese birds com- 

 menced constructing their nests as early as 

 December 25th, though the regular breeding 

 season is from the middle of January until the 

 end of March. The " nests were found in cav- 

 ities of imense boulders, under I'ocks, in fallen 

 and decayed trunks of trees, the latter location 

 being apparently a favorite one. But where- 

 ever the nests were located the passages leading 

 to them were, with one or two exceptions, paved 

 with fiat pebbles ranging in size from a Lima 

 bean to a half dollar. Fully a quart of these 

 pebbles wei'e removed from the entrance to a 

 nest built in a boulder at a height of four feet, 

 where, at some previous time, other birds had 

 evidently built and contributed their share of 

 the pavement. As a rule scarcely an ordinary 

 handful of stones are used. The nest is built 

 in close conformity to the size and shape of tht; 

 cavity which it occupies, being usually circular 

 and varying from a shallow bed of fine dry 

 grasses to a nest of the same material meas- 

 uring 150 mm. in diameter and 00 mm. high. 

 The egg receptacle is from 55 mm. to 70 mm. 

 in diameter, and not more than 30 mm. in depth.
