Field identification of individual Little Bustard Tetrax tetrax males using plumage patterns.
Little Bustard (Tetrax tetrax) Science Article 1 abstract We examine the variability in phenotypic characteristics in Little Bustard Tetrax tetrax males to determine which are the elements that better allow individual recognition throughout a season. Six variables were chosen, for which individual variations could be classed into clearly distinguishable categories and for which all categories […]
