Methods
The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures
Current Methods
Bird counts
Started: 1991-06-01Counts began shortly aftern dawn on days where weather conditions were unlikely to reduce count numbers (i.e., calm winds and very light or no rain).
Point count intervals
Started: 1991-06-01Observers recorded all birds seen and heard during a 10-min sampling period, which was divided into 3 time intervals: 3, 2 and 5 minutes. Observers noted in which time interval each bird was first encountered, and placed birds into one of 2 distance categories (within or beyond 50 m).
Elevation-dependent sampling
Started: 1999-05-01The number of surveys at each site was dependent on elevation; montane fir-spruce sites were sampled once, LBWA and Underhill were sampled twice during the breeding season.
