Age and sex determination of monomorphic non-breeding choughs: a long-term study
Chough (Pyrrhocorax pyrrhocorax) Science Article 1 abstract We present criteria for sexing and aging non-breeding Choughs( Pyrrhocorax py rrhocorax) based on nine years of capture-recapture data. Shape of the rectrices, intensity of plumage colour and iridescent brightness , and the contrast between old flight feathers and freshly molted ones allowed us to distinguish three age […]

AMERICAN WIGEON MORTALITY ASSOCIATED WITHTURF APPLICATION OF DIAZINON AG500
American Wigeon (Anas americana) Science Article 1 abstract Nine fairways of a golf course located in Bellingham, Washington were treated with diazinon AG500 at a target application rate of 2.2 kg active ingredient (Al) per ha. The chemical application with a ‘boomless’ sprayer resulted in a variable distribution of diazinon residues on the turf (associated […]
