| Abstract |
A study on the distribution, abundance, and habitat requirements of flame-templed babbler (Dasycrotapha speciosa) and Negros-striped babbler (Stachyris nigrorum) in Mt. Kanlaon Natural Park was conducted from 18 May to 2 June 2015. A total of 44.5 km of transects were surveyed using a combination of line transect and point count methods while 567 circular plots measuring 30 m x 30 m were established for habitat assessment. A total of 27 individuals of the flame-templed babbler were recorded in habitat types occurring from 604脙垄脗聙脗聯1,078 masl while 14 individuals of the Negros striped-babbler was encountered in primary forest and secondary montane forest from 1,105脙垄脗聙脗聯1,927 masl. D. speciosa was abundant in secondary lowland forest (n=16) while S. nigrorum was abundant in secondary montane forest (n=8). The presence of D. speciosa in plantation denotes that this forest serves as temporary habitat for this babbler. Both logistic regression analysis and Poisson distributions showed that increased percentage of climbing bamboos and trees with 16脙垄脗聙脗聯20 m height and decreased elevation implied increased likelihood of the occurrence and abundance of D. speciosa.
