“…The secretory epithelium of the six species included in our study was composed of the same epithelial layers as those of other species (Jacob and Ziswiler 1982;Montalti et al 2001;Sawad 2006;Harem et al 2010;Kozlu et al 2011;Sadoon 2011). The lobes showed a PAS positive reaction, as demonstrated in the rock pigeon (Columba livia) (Montalti et al 2001).…”

“…The histology of the uropygial gland has been studied in different bird species and some dissimilar characteristics have been described (Hsu 1936;Bo 1953;Bhattacharyya 1972;Bride 1975;Menon et al 1981;Kamiya et al 1986;Suzuki 1994;Montalti et al 2001;Sandilands et al 2004;Sawad 2006;Harem et al 2010). However, no studies have linked the histological structure of the gland with the environment.…”

The uropygial gland is morphologically different in diverse bird species. This gland was macroscopically and microscopically examined in penguins, storm petrels and skuas. In all the studied species, the gland showed a connective tissue capsule and one papilla. A negative relationship was observed between the relative glandular mass and the body mass, being highest in petrels (small glands) and lowest in penguins (large glands). Birds that spend much time in water (penguins) have gland characteristics related to a continuous, but not stored, secretion, such as straight adenomers, the presence of abundant elastic fibres in the connective tissue and the absence of a primary storage chamber. Instead, birds that have less contact with water (storm petrels) have a gland with much more tortuous adenomers and a small primary storage chamber. The secretory cells showed a positive PAS reaction in all the glandular zones. Therefore, no differences could be seen between the sebaceous and glucogenic zones, as proposed in other birds. These results allow the conclusion that, in aquatic birds, there is no connection between the relative mass of the uropygial gland and the time in contact with water, though the differences found in the histological structure could be related to a different contact with the aquatic environment.

“…The shape is as has been described by Johnston (1988) for this species. The uropygial gland of the Southern Caracara has a primary chamber or cavity, and this structure is also present in other bird species (Jacob and Ziswiler 1982;Harem et al 2010;Kozlu et al 2011;Chiale et al 2015). The uropygial gland of the Southern Caracara has a primary chamber or cavity, and this structure is also present in other bird species (Jacob and Ziswiler 1982;Harem et al 2010;Kozlu et al 2011;Chiale et al 2015).…”

“…These researchers have pointed out to differences in the thickness of trabeculae and the cells composing the epithelial layers lining the tubules in the glandular structure pertaining to wild and domestic ducks. In a previous study conducted by Harem et al (2010) in the osprey, the epithelium lining the tubules was determined to be composed of 4 different types of epithelial cells from the base to the lumen. Similar findings were obtained in the uropygial gland of the stork in the present study.…”

“…These cavities collect the secretion of tubules, which are arranged radially in their periphery. The secretion of the gland is transported to the surface of the skin by ducts and is discharged into a narrow papilla, which in general is single in number (Sawad, 2006;Harem et al).…”

KOZLU, T.; AKAYDIN BOZKURT, Y. & ATES¸, S.A macroanatomical and histological study of the uropygial gland in the white stork (Ciconia cicionia). Int. J. Morphol., 29(3):723-726, 2011. SUMMARY:The present study was aimed at the macroanatomical and histological investigation and the demonstration of the structural characteristics of the uropygial gland in the white stork. The uropygial gland of two adult male white storks constituted the material of the study. It was determined that the gland was situated subcutaneously in between the caudal aspect of the lumbosacral bone and the first coccygeal vertebrae. The gland was composed of two lobes, which displayed an oval appearance when viewed from above and resembled a water drop when observed medially. Tuft of feathers were present on the caudal margin of each lobe. The present study revealed that the uropygial gland of the white stork is a simple tubular gland, which discharges its secretion into the lumen by a holocrine mode. Each lobe, possessed centrally located large cavities and a main excretory duct and displayed the presence of externally situated "peripheral tubules" and interiorly situated "central tubules". These secretory tubules, which composed the parenchyma, were separated by connective tissue septa referred to as "trabeculae", and released their secretion into a centrally located lumen. The wall of the secretory tubules was comprised of four layers, referred to as the germinative, intermediary, secretory and degenerative layers. The silver-staining procedure demonstrated that the stroma of the uropygial gland did not contain reticulum fibres. The anatomy and histology of the gland has been examined in few avian species. Up to date, this study is the first to describe the histological and anatomical peculiarities of the uropygial gland in white stork. The results acquired hereby will surely contribute to further studies to be conducted on the related area.
