(IREAT UESTRUCTION OF BIRDS’ EGGS AND NESTLINGS 
83 
June 7 and July 9, 1912, within a radius of two miles of Cisco Postoffice, will en- 
able the reader to form a fair idea of the tremendous loss in young- birds and 
eggs in nests exposed to the elements and to the jays. 
One nest of Plumed Quail ( Orcortyx p. plumifera) . The nest was evident- 
ly destroyed by an animal having sharp claws and long black hair — presumably a 
skunk. Sticky pieces of egg-shell were scattered around the nesting hollow. 
One nest of Red-breasted Sapsucker (Sphyrapiciis daggeiti). Nest about 
ready for eggs, v/hen birds were shot by a man camping under a nearby tree. 
One nest of Olive-sided Flycatcher {Nuttalloniis borealis). Nest was ex- 
amined by means of a glass from a distance of 80 or 90 feet below. Previous to 
June 22 the birds were often seen, but not after that date. 
Three nests of Traill Flycatcher (Eiiipidonax trailli). A jay was seen at 
nest that had contained two eggs a few hours before. The other nests were 
wrecked, before completion, by miow bending apart the willow stems between 
which the nests were placed.

Nine nests of Western Wood Pewee { Myiochaiics r. ricliordsoiii) . One nest 
and three eggs were taken by myself. One was partially dislodged by a scjuirrel 
running over same, when frightened by me while climbing an adjoining tree to 
examine a Kinglet’s nest. Two nests were wrecked by snow. Two were emp- 
tied by jays ( ?). A bird was flushed from a single egg in a nest that contained 
two eggs when examined a few days previously. Two nests containing two and 
three eggs, respectively, were later observed to have brooding liirds on each. 
Four nests of White-crowned Sparrow (Zoiwtricliia /. Icucophrys). One 
incomplete nest abandoned ; also a nest with a fresh egg was abandoned for rea- 
son unknown to me. A nest with four eggs was later found to contain but a 
single sucked egg. One nest and four eggs were taken by a guest at the hotel. 
Seven nests of Western Chipping Sparrow (Spieiella p. aricoiine). One 
nest and four eggs taken by a guest at the hotel. Two ne.sts were emptied bv
