Wing morphometrics

The Redshank is a wader species that shows no sexual dimorphism in plumage, but some dimorphism in size. To propose a method for sexing birds of this species by linear measurements, a discriminant function analysis was applied to a set of morphometric traits in birds captured during the spring migration in southern Belarus. In total, 113 males and 75 females were measured and sexed molecularly. On average, females were larger in all measurements than males. The most sexually dimorphic trait was wing length, which was included in the discriminant function analysis.

Apis mellifera scutellata and A.m. capensis (the Cape honey bee) are western honey bee subspecies indigenous to the Republic of South Africa (RSA). Both bees are important for biological and economic reasons. First, A.m. scutellata is the invasive “African honey bee” of the Americas and exhibits a number of traits that beekeepers consider undesirable.

Knowledge about the morphological adaptations of body and wing in birds helps to know about their aerodynamic performance. The present study was aimed to analyze the morphometry of the wing of the blue and yellow macaw (Ara ararauna) with reference to aerodynamics. Various aerodynamic measurements namely body weight, body length, wing span, wing area, wing load and aspect ratio were measured in three adult male birds. The wings were short, elliptical and rounded.

A study was conducted at department of Poultry science, Madras Veterinary College, Chennai to record the qualitative characters of Aseel male chicken and to measure the biometric Characters of the birds. The skin, shank and eye colour were yellow and the colour was red in all the birds (100%). Sixty per cent of bird had red ear lobe and remaining 40% had pinkish red ear lobe. The comb type was ‘Pea’ in 80% of the birds, while it was ‘Rose’ in the remaining birds (20%). The beak colour was either brownish yellow (60%) or blackish yellow (40%). None of the birds had wattles (0%).
