• Site establishment and measurements
  • Started: 1992-06-01
    
  • Method Description: An 8.8 ha population monitoring plot was established south of the summit of the mountain in 1992, where 5-30 m radius circles per forest type were used for point counts and habitat plots. This ranged in elevation from 1160-1200 m, in krummholz and spruce-fir forests. Measurements included species, frequency, sighting locations, habitat measurements.

• Additional Plots 1995
  • Started: 1995-06-01
    
  • Method Description: Additional plots added in 1995: a 20 ha plot in Ranch Valley, and a 20 ha plot at a lower elevation in the Nose Dive Pod area. Elevation range expanded to 885-1200 m. 25 m grid sampling points used. Measurement include: population density, territory dispersion, sighting locations and movements of known-identity individuals, habitat measurements, survival and productivity and site fidelity.

• Additional Plot 1996
  • Started: 1995-06-01
    
  • Method Description: An additional plot was added in 1996: a 10 ha plot northeast of the Forehead, off the Long Trail in spruce-fir forest.

• Reduced Plot 1997
  • Started: 1998-06-01
    
  • Method Description: Nose Pod Dive plot discontinued after 1997.

• Mist nets and vocal lures
  • Started: 1992-06-01
    
  • Method Description: Strategically placed mist nets were deployed on two plots (Mansfield ridgeline and Octagon) in combination with tape recorded playbacks of Bicknell's Thrush vocalizations to attempt to capture and color band Bicknell’s Thrushes.

• Passive mist nets and metrics collected
  • Started: 1992-06-01
    
  • Method Description: Up to 30 mist nets were used simultaneously to passively capture thrushes as a complement to the use of vocal lures. Detailed mensural (e.g., wing chord, weight, tarsus, culmen) and body condition (e.g., subcutaneous fat, molt, feather wear) data were recorded for all captured birds. Sex was determined by status of cloacal protuberance and brood patch. Individuals were aged, too.

• Banding
  • Started: 1992-06-01
    
  • Method Description: Each individual was banded with a numbered aluminum band and three color bands to uniquely identify birds for resighting.
