Transect observation and counting methods were applied in the simplest way to observe the birds during the research. Aim of the count is to separate the bird species into ordinal categories of their abundance. As a result of this study 47 of 88 bird species found in research area are insectivorous bird species. They belong to 19 families. When encounter rates of insectivorous birds are considered, one of them is common, nine of them are frequent, thirty six of them are uncommon and one species is rare.
