out and hanging over the rim; as if the horsehair or other fine 

 material, had been caught on the claws of some small mammal. These 

 depredations, apparently occurred at night and were done at a time 

 when squirrels and chipmunks had been cleaned out of the orchard. 



The following notes show the gradual increase of mountain- 

 breeding birds and the first movement of the fall migration. 



July 12, 1916 A slight increase in the numbers of birds in the 

 orchard. Broods of Audubon Warblers (Dendroica auduboni audu- 

 boiii), Western Vesper Sparrow, Shufeldt's Junco (Junco hyemalis 

 connectens) , and Calaveras Warbler (Vermivora rubricapella 

 gutturalis) appear. 



July 15, 1916 The hedge full of birds, feeding on service 

 berries; Catbirds unusually plentiful. 



July 26 to July 28, 1916 Hundreds of swallows of all species, 

 passing through. 



July 16 to August 8, 1916 A steady increase during this time. 

 Broods of Red-naped Sapsucker, Townsends Solitaire, Wright's Fly- 

 catcher (Empidonax wrighti) and Olive-backed Thrush (Hylocichla 

 ustulata swainsoni) appear. 



August 10, 1916 Large flocks of Cassin's Purple Finch, juvenals 

 and adults arrive. 



August 11, 1916 Spurred Towhee, adults and juvenals very 

 plentiful. Several juvenal W'estern Evening Grosbeak (Hesperiphona 

 vespertina montana) and Lazuli Bunting (Passerina amoena) seen. 



August 12, 1916 Large increase in the number of Bullock's 

 Oriole and further increase of Cassin's Purple Finch. 



August 14, 1916 Bullock's Oriole, Cassin's Purple Finch, and 

 Western Tanager very destructive in the orchard. The locally bred 

 robins have left. 



August 15 and 16, 1916 The orchard nearly empty of birds. 



August 17, 1916 Large flocks of Shufeldt's Junco, Pine Siskin 

 (Spinus pinus), Western Robin and Western Chipping Sparrow 

 arrive. Arkansas Kingbirds and Bullock's Orioles have all left. 



August 20, 1916 Nearly all the catbirds have migrated. 



August 21, 1916 The common kingbird left to-day. 



August 24, 1916 Cedar W T axwing and Cassin's Purple Finch 

 are still numerous. The former prefer the wild fruit to the 

 domesticated.
