| Abstract | ||
| The white-breasted waterhen is a widely distributed wetland species that inhabits waterlogged environments consistently throughout the year. The small water birds are good hunters of worms, insects, and small fish. This bird uttered loud calls during the periods of its courtship display, incubation, and caring for the young. Although several studies have been done on the white-breasted Waterhen bird, little attention has been paid by ornithologists to its visceral organs. Therefore, this study aimed to describe the macro- and microanatomical features of a white-breasted waterhen bird's visceral organs and compare them with domestic birds. This study showed that the bird had a black coat color on the dorsal part of the body, but the white color extended from the base of the beak to the vent as the ventral region of the body through the breast. The beak and legs display a subtle pale yellow hue extending along their length. Legs and fingers are long and bony. At the bifurcation of the trachea, there was a laterally swollen structure called the syrinx, more well-developed than domes-tic chickens and capable of producing the loud call. The esophagus was a long, thin-walled, dilatable tube without any crop. Gizzard was comparatively softer in consistency. The length of the duodenum and jejunum is relatively smaller than that of other domestic avian species. There was a poorly developed caecum, and the colo-rectum was shorter in length. Interestingly, the spleen was elongated, different from that of other avian species. The right hepatic lobe was observed to be larger than the left as usual. All these anatomical modifications might be due to their environmental adaptation. Thus, this research will help our clinicians and conservationists take further steps toward disease diagnosis and monitor the conservation of this species. | ||
