Gracula religiosa intermedia once a month for 12 months in 2002. The majority of Hill Mynahs were infected with Myrsidea invadens (64%) and Brueelia chayanh (34.5%). The other four ectoparasites found, accounting for 1.5% of all, included: Androlaelaps casalis (0.3%), Ornithonyssus bursa (0.4%), Montesauria sp. (0.7%) and Analges sp. (0.1%). On average, eleven M. invadens and six B. chayanh were found per bird. The study of habitat preferences and intensities of M. invadens and B. chayanh showed that the two species avoided interspecific competition. M. invadens preferred dorsal area whereas B. chayanh preferred ventral area of birds. The number of M. invadens was low in January, February and March meanwhile the number of B. chyanh was high but when the number of M. invadens was high in June, July and August, the number of B. chayanh was low. Although no bird died in this study, these ectoparasites caused weakness and weight loss by eating skin and annoying.]]>
