2 1/4 mi. S + 1/2 mi. W Inyhean Ple., 2000 m., San
Bernardino Co., Calif. [T. 2N, R. 2W]
29 July Chickadees again thick here. Lots of flocking
young birds.
Black Mtn. Area, 1740+1820m., Pasadena Co., Calif.
[T. 4S R. 2E]
30 July Chickadees again quite common + flocking. Song
here seems normal, perhaps slightly higher on 3rd
note.

Co., Calif. [T. 15 S, R. 5E, SE 1/4 sec. 20]
1 August Chickadees sound normal, but with odd (prob.
juvenile) songs it is hard to say.
