  • (1) Method used for measuring from Baldwin et al. (Baldwin et al. 1931).
  • (2) Wing measurements are unflattened chords.
  • (3) Tarsus measured from the midpoint of the posterior juncture of the tibia and the metatarsus to the anterio lower edge of the scute opposite the insertion of the proximal base of the hind toe.
  • (4) Culmen length measured from the edge of the skin covering the culmen near its base to the bill tip.
