“…In Garganey, the stomach consisted of glandular proventriculus and muscular gizzard, similar results reported by Dursun (2002) in domestic birds, Jassem, Hussein, and Sawad (2016) in common moorhen and Ince, Pazvant, and Kahvecioglu (2010) in sea gull,…”

“…In Garganey, the stomach consisted of glandular proventriculus and muscular gizzard, similar results reported by Dursun () in domestic birds, Jassem, Hussein, and Sawad () in common moorhen and Ince, Pazvant, and Kahvecioglu () in sea gull, whereas Hodges () recorded that the stomach of birds consisted of proventricular, ventricular and pyloric parts. Our results agree with Hassouna () and Rossi et al () who reported that the proventriculus separated from the stomach by the isthmus, while Rossi et al (), El‐Ghazali () and Abumandour () in cattle egret, ibis and Eurasian Hobby, respectively, reported its absence.…”

The present work was aimed to study the gastrointestinal tract in Garganey from the oesophagus to coprodeum by the aid of the gross morphology, scanning electron microscopy and histology. At the level of the thoracic inlet, the oesophagus had a thick part which had numerous tortuous longitudinal folds carried transverse folds on them. Histologically, the thick part had thick epithelium and appeared more folded with more and larger glands. The mucosa of the proventriculus had mucosal folds appeared as a leaf‐like with rounded tips. The openings of the proventriculus glands were projected with papillae on the epithelial surface. The gizzard lined with horizontal layer of cuticle which sent vertical parts of cuticle. The duodenal villi were pentagonal in shape with sharply pointed tips, while the jejunal villi were triangular with rounded ends, and the ileal villi were wide and pentagonal in shape with pointed tips. The mucosa of the duodenum, jejunum and ileum was thrown into villi lined by simple columnar epithelium with goblet cells with difference in the form, length, density and number. The apical points of the duodenal and ileal villi appeared pointed, while the jejunal villi had rounded ends. The jejunal villi were longer and numerous than the duodenal villi, but the ileal villi appeared with different length and less numerous. The mucosa of the caecum had numerous mucous glands which surrounded by circular crypts. The rectal mucosa had longitudinal folds and semilunar and circular crypts. The mucosa of the coprodeum had longitudinal folds surrounded by crypts.

“…The present investigation declared that the stomach of the Eurasian common moorhen consisted of proventriculus and gizzard. This coincides with Dursun (2002) in the domestic birds, Hanafy et al (2020) in Garganey, Ince, Pazvant, and Kahvecioglu (2010) in sea gull, and Madkour and Mohamed (2019) in the rock pigeon and the Egyptian laughing dove. Whereas, El Nahla, El Mahdy, and Basha (2011) in cattle egret reported that the stomach was composed of cranial proventriculus, caudal ventriculus, and small pyloric part.…”

The present work was the first attempt to examine the oesophagus and stomach of the Eurasian common moorhen grossly and by SEM. The oesophagus was composed of long cervical and short thoracic parts. The longitudinal folds of the cervical part were narrower than that of the thoracic part, while the depressions between these folds were shallower and wider in the cervical part. On the epithelial surface of the oesophagus, micropapillae were present and they were numerous and smaller at the level of the cervical part. The openings of the oesophageal glands were circular at the level of the cervical part and oval to elliptical at the thoracic part. The crop was absent. The proventriculus was fusiform in shape; its mucosa was arranged in several, concentrically arranged mucosal folds connected with each other by transverse folds. The proventriculus glands were oval and opened by raised papillae on the epithelial surface. The gizzard was oval; its mucosa was lined by a horizontal layer of cuticle appeared like the fish scales, while the vertical part of the cuticle appeared as thin rods. The folds of the oesophagus are functioning for the expansion for the passage of the food particles. The tunica musculosa of the gizzard was thick to help in grinding of the food particles.

“…For this reason, the tongue differs depending on the nutrition, type of food consumed and the shape of the lower beak (3,16,31). In the morphological studies, it has been reported that the tongue is in the form of a triangle in seagull (24), white-eared bulbul (32), black francolin (28); toothpick like in Japanese pygmy woodpecker (13); protruding arrow like in the African pied crow (21); arrow like in the hooded crow (11); needle like in the heron (12); mushroom in hummingbird (34); spearhead like in the jungle nightjar (14); lip like in the scarlet macaw (15); and rasp like in penguins (29). The present study revealed that the merlin tongue was thin and elongated rectangular in shape and its tip was oval similar to the white-tailed eagle (25), golden eagle (33), and hawk (38) tongue.…”

The study aimed to reveal the similarities and differences of the tongue of the merlin with other bird species. Merlin is the smallest bird of the Falconidae family and lives in America, the northern regions of Europe and Asia, the Middle East, and Central Asia. Since these species don’t have teeth, lips, and cheeks, the tongue fulfills significant functions related to nutrition, and it differs morphologically as a result of differences in eating habits. In this study, the tongues obtained from five adult merlin (falco columbarius) were examined by morphological and stereological methods. It was determined that the tongue of the merlin was thin, long, and rectangular, the front part was oval, W-shaped papilla linguales caudales were found between the body and root of the tongue. The average length of the tongue was 26.32 ± 1.38 mm, the width was 7.26 ± 0.32 mm, and the thickness was 1.58 ± 0.14 mm. The histology of the tongue showed that the dorsal and ventral surfaces are covered with keratinized multilayered squamous epithelium; there are taste buds in the epithelial layer, the number of taste buds is higher especially on the root of the tongue; and the presence of paraglossum, which is in the hyaline cartilage structure. The volume of the tongue was on an average of 374.2 ± 14.08 mm3.
