    Methods

    • Current Methods
      • Capturing study specimens
        • Started: 2000-05-01
        • Method Description: Individuals of the focal avian species, Bicknell's thrush, were captured using standard arrays of 6-m and 12-m, 36-mm nylon mist nets throughout the study site. All captured birds were banded with USFWS aluminum leg bands, aged, and sexed according to standard criteria and weighed prior to release. A series of morphometric measurements was also taken.

      • Collecting blood samples
        • Method Description: From each individual, 30-50 microliters of blood were collected from the cutaneous ulnar vein. Subsequent blood samples were selectively collected from individuals captured one week or more after collection of their previous sample.

      • Sample processing
        • Method Description: Sampled were analyzed at the Texas A&M University Trace Element Research Laboratory. Total mercury was measured in each compartment.
