SEX-RATIOS OF AN ENDANGERED LARK AFTER CONTROLLING FOR A MALE-BIASED SAMPLING.

The article explores the application of avian sex ratios to the Dupont's lark Chersophilus duponti in Spain. The species, accordingly, has already been considered as near-threatened by the International Union for the Conservation of Nature (IUCN) criteria as well as endangered in Spain. To investigate the effect of adult sex ratio, both male and female Dupont's larks were subjected in a study which attempts to answer whether a failure to achieve 1:1 sex ratio in one trapping means unbalanced sex ratios into the population during the breeding season. Nonetheless, the author claims that the concept of adult sex ratio is needed in order to clarify the conservation status of the said species.
