“…The lingual glands were complex glands within the LP of the tongue of the Muscovy duck; similar result was mentioned by Skieresz-Szewczyk and Jackowiak [41] and Taki-El-Deen [42] in domestic duck, Liman et al [52] in Japanese quail, Rossi et al [53] in partiqe, El Bakary et al [26] in Anas crecca, Crole and Soley [50] in Emu, Parchami and Dehkordi [37] in common pigeon, Igwebuike et al [51] in domestic pigeon, Al-Nefeiy [31] in laughing dove, and Jackowiak and Godynicki [13] in white-tailed eagle. Furthermore, the Muscovy duck can also feed on dry and semi-dry food since the complex lingual glands secrete mucous which can moisten these foods and lubricate the caudal part of the oropharynx and the initial part of the esophagus for easy swallowing.…”

“…Moreover, the mucous secretion can act as a glue to stick the small food particles either with each other or with the lateral conical papillae to prevent food loss during ingestion; similar results were recorded in Muscovy duck [7], domestic duck [41], in white-headed duck [30], and in Anas crecca [26] and in ostrich [11]. Also, the lingual glands protect the tongue from dryness in Muscovy duck [7] and from coarse food and microorganisms in domestic duck [42]. On the other hand, the lingual glands are not observed in cormorant [16] and in whimbrel [42].…”

“…Moreover, The Muscovy duck can feed by grazing which entails grabbing and dragging of the grass between the beaks then tearing the leaves using the bottom beak lamellae and large caudal conical papillae on the side edges of the tongue; similar result was mentioned by Skieresz-Szewczyk and Jackowiak [41] in domestic duck, Van der Leeuw et al [23] in Anseriformes, and Akbari et al [30] in white-headed duck. Taki-El-Deen [42] stated that the tongue of whimbrel has no lingual papillae.…”

Objective: The objective of this study was to give detailed descriptions of the morphological and histological structures of the tongue of the Muscovy duck as it relates to their feeding habit. Materials and Methods: Ten adult Muscovy ducks weighing 2–4 kg were used. The ducks were slaughtered and their oral cavities were opened to detect in situ position of the tongues. Each tongue was dissected and examined grossly. Samples of various parts of the tongue were taken for routine histological examination. Results: The tongue of the Muscovy ducks was distinguished grossly as the apex, body, and root. A dorsal median sulcus, conical papillae, and lingual prominence were observed grossly. Microscopic observations showed the tongue of the Muscovy duck was covered by stratified squamous epithelium; keratinized and non-keratinized. The lamina propria of the tongue contained lingual glands, entoglossum cartilage, lymphoid nodules, as well as blood vessels and nerves. Conclusion: The morphological and histological variations of the tongue of the Muscovy duck may infer that its unique structures are related to their feeding habits.

“…There is a correlation between bird's diets and the lingual epithelium morphology. Several studies showed that the structure of the bird's tongue depend on the feeding habit and consumed food (Jackowiak and Godynicki 2005;Jackowiak and Ludwig 2008;Tivane 2008;Taki-El-Deen, 2017). Many authors revealed that there is a close correlation of the structure of the surface epithelium with the style of food swallowing and the kind of food (Mclelland, 1975;Iwasaki et al, 1997;Homberger and Brush, 1986;Shawki and Abdel-Rahman, 1998).…”

The aim of this study is to examine the dorsal lingual epithelium of the peregrine falcon (Falco peregrinus) of the family Falconidae. The tongue in its dorsal, lateral and ventral surfaces is covered with a non-keratinized multilayered stratified squamous epithelium. Lamina propria is present beneath the epithelial layers. Morphometrically, thickness of the apex tongue epithelium is more than that in the tongue body. Thickness of the ventral surface of the tongue is less than that in the dorsal one. Thickness of the lateral surface of the tongue was thicker than that in the ventral one and tongue body. Large and small conical papillae appeared on the posterior dorsal surface of the lingual body. There are lingual glands in certain areas of tongue body with numerous openings through the dorsal surface.

The oesophagus is a muscular tube comprised of cervical and thoracic regions. Several studies have clarified the histological structure of the oesophagus. However, its histoarchitecture in relation to variable dietary habits of each species is still unclear. In the current study, 21 pigeons, cattle egrets and ducks, n = 7, each was used. Macroscopically, the oesophagus of cattle egrets either the cervical or thoracic parts was the longest among the pigeons and ducks. Histologically, the oesophagus comprised of four distinct tunicae: mucosa, propria submucosa, musculosa and adventitia or serosa. A great structural variation in these layers among the three investigated species was recorded. In the cervical oesophagus of pigeons, the superficial squamous cells showed perinuclear halo zone, the propria submucosa was characteristically lacked any gland. Moreover, its musculosa was very thick. On the other hand, the intraepithelial glands were characteristically distributed along the whole length of the cattle egret’s oesophagus. Interestingly, the cervical esophagus of the ducks showed submucosal associated lymphatic tissue; diffuse and nodular Ultrastructurally, the oesophageal glands showed secretory granules of variable electron densities, electron‐lucent in the pigeons and ducks and electron‐dense in the cattle egrets.
