INTRODUCTION Understanding the basic ecology of a bird species starts from its distribution, at least from nearest history until nowadays, does the distribution broaden or tighten, what is the population trend, what is the habitat requirement and availability of potential nesting habitat for the species, clutch and brood size, sex and survival rate at different ages. It is important to understand the features of high-quality nesting sites while the production of the offspring that eventually recruited into the breeding population is related to territory quality (Sergio et al. 2009).
