ИСТИНА

Despite the small number of species, breeding biology of broadbills (Eurylaimidae – a family of the Old World Suboscines passerines) is still poorly studied. I explored characteristics of nest locations in the Black and Red Broadbill (Cymbirhynchus macrorhynchos) in Cat Tien National Park (southern Vietnam). I searched for nests in the forest, paying special attention to forest clearings of natural and artificial origin. For each nest (n>200) I recorded several characteristics: height above the ground, nest site, habitat type, illumination, entrance orientation, etc. Broadbills preferred to build nests in the relatively open, light-filled forest areas like openings, wide stream beds and ponds, and especially forest roads. I will discuss factors, which affect the choice of nesting location in the C. macrorhynchos.
