title: Demonstration of acid phosphatase activity in the proventriculus of common weaver bird, Ploceus philippinus and whitebreasted kingfisher, Halcyon smyrnensis.
abstract: Acid phosphatase activity was histochemically localized in the proventriculus of two birds namely Ploceus philippinus and Halcyon smyrnensis. It was found that acid phosphatase-rich lysosomal activity appears to be relatively better developed in the proventriculus of piscivorous form, H. smyrnensis than that of granivorous form. P. philippinus. Simultaneously, a possible correlationship between the variable lysosomal activity and specific food diets of the birds has been discussed.
