Abstract: 

Chrysomma sinense sinense breeds only in the scrub forest and the success was only 25% during 1999- 2001. To provide the feeding and breeding biology especially nest-site characteristics of the Yellow[1]eyed Babbler in tropical forest, India. Field observations on feeding and foraging behaviour, estimation of insect availability and breeding strategy by opportunistic and behavioral methods in 5ha area. The Yellow-eyed Babbler is distributed mainly in the Scrub forest where C.odorata, L.camara and P.indica are more. Four plant species have been selected by this bird to feed on the preferred height between 0 and1m, fed mainly on insects by gleaning on twig partly on leaf, from the middle and edge than center of the horizontal strata of the plant. Altogether, 35 nests were observed. Of the 28 successful nests studied 21 were built in Chromolaena odorata and 7 in Pavetta indica. There existed two breeding seasons from October to January with peak in November and April to June. Average clutch size was 3.4+ 0.6 and preferred more of C. odorata (75%) and less of P. indica (25%) for nesting. Both parents participated in all the nesting activities. Incubation and nestling period was about 13 and 12-13days respectively. Predation, anthropogenic pressure along with cattle grazing which has to be arrested. YEB appeared to select scrub forest as the specific nest-sites; hence the landscape is important for the conservation of this species before it becomes included in the IUCN Red Data Book list.
