The bird´s uropygial gland has a papilla in its caudal end and it can also show a feather tuft. These feathers may have a raquis or not. The purpose of our study was to compare the number, dimensions and types of the tuft´s ...
Physiological and biochemical aspects of the avian uropygial gland
(Instituto Internacional de Ecologia, 2009)
This review discusses different aspects of the uropygial gland of birds. The gland exhibits a striking morphological
diversity in size, shape and presence/absence of tufts of feathers. It was shown that acidic mucins, ...
