Stray notes on two phthirapteran species occurring on Indian grey Horn Bill, Tockus birostris Scopoli (Coraciformes: Bucerotidae)

Two phthirapteran species (an amblyceran Chapinia clayae and an ischnoceran, Buceroemersonia clarkei) were recovered from eight Indian grey Horn Bills, during 2009 in district Rampur (India). The occurrence of B. clarkei on Indian birds has not been noted earlier. The population characteristics of both the species have been recorded. On the basis of crop contents C. clayae appeared to be a probable haematophagous. The egg chorion of B. clarkei appeared smooth that of C. clayae bears sculpturing.
