BIRD SPECIES DATABASE OF EGG VOLUMES AND SURFACE AREAS

I. S. Mytiai, A. V. Matsyura

Abstract


The computer-based analysis of 13458 photographs of avian eggs belonging to 257 species of 19 orders provided empirical data for the coefficients of egg volume and surface area calculation using the dimensions of length and breadth. The calculated species-specific and order-specific coefficients are given. The method of estimation of egg volume and surface by means of taking digital photographs with further computer calculation may be used to study the intrapopulation variability and to estimate incubation efficiency.


Keywords
