Troglodytes aédon parkmanii (Audubon). Parkman Wren. 
The Parkman wren was met with commonly in June and July 
of each year in the vicinity of Seven Oaks, where broods of full- 
grown young were often seen. The species was also nesting in 
the lower part of Mountain Home canon, where, near Skinner’s, 
June 9, 1906, a nest with four eggs was found in a hole in an alder 
seven feet from the ground; and another nest with young was 
loeated. I do not believe the species breeds much above the upper 
edge of Upper Sonoran—the lower Transition at highest. Early 
in July a general scattering began, and Parkman wrens were 
noted almost everywhere we went thereafter. In Foresee creek 
canon, up to 7000 feet altitude, several were seen on July 12. 
By July 15, 1906, they had appeared commonly along the upper 
Santa Ana, and its tributaries, one beine seen as high as the 
South Fork cienaga, 8500 feet. At Bluff lake Parkman wrens 
were common in the willow thickets in July and up to September 
3, 1905. They were also numerous in August at the north base 
of Sugarloaf, about springs at Doble, Cactus Flat, and Cushen- 
bury springs. A series of twenty-one examples were taken. 
In all these localities they were doubtless purely migrants. I 
had in previous years wondered what became of the many Park- 
man wrens with their large families, which had been reared in the 
foothill canons of Los Angeles county. They were wont to for- 
sake the region in July almost completely. It is now plain that 
there is an upward movement in summer into the higher moun- 
tains where food conditions are better at that season. 
Certhia americana zelotes (Osgood). Sierra Creeper. 
The Sierra creeper was found to be chiefly an upper Transi- 
tion bird, though it ranged into lower Transition below and into 
Boreal above. It was very common along the upper Santa Ana 
and the tributary canons running down from the San Gorgonio 
ridge. It was noted at Dry lake, 9000 feet elevation, up to 8500 
feet near the head of the South Fork, on the north side of Sugar- 
loak at 8500 feet elevation, and on San Bernardino peak at the 
same altitude. It was also common at Bluff lake, both in July 
and the last of August and the first of September. It was seen
