“…Lonchura striata and Copsychus saularis both belong to Passeriformes, and their habitats are relatively similar, but there are some differences in feeding habits. And there were no significant differences in jejunum length, ileum length, whole digestive tract length and weight between adult Lonchura striata and Copsychus saularis (Huang et al, 2020). In this study, our goal is to describe morphological structure of small intestine of Lonchura striata and Copsychus saularis by paraffin sections, H. E. (Hematoxylin Eosin) staining, micrography, quantitative biology and image analysis.…”

Six Lonchura striata and six Copsychus saularis birds were selected in this study, morphological index of the small intestine was measured by quantitative biology and image analysis. The changes of goblet cells and Na + /K + ATPase were detected by AB-PAS staining and ELISA to inform the different mechanisms of the digestion and absorption of nutrients between the Lonchura striata and Copsychus saularis. The villus height, crypt depth and muscle thickness of each segment of small intestine of Lonchura striata were smaller than those of Copsychus saularis, and the difference of ileum muscle thickness was significant. In addition, the ileum villus height/crypt depth (VH/CD) value of Lonchura striata was significantly less than that of Copsychus saularis. The number of goblet cells in duodenum and jejunum of Lonchura striata and Copsychus saularis had no significant difference, but the number of goblet cells in ileum of Copsychus saularis was significantly larger than that of Lonchura striata. The vitality of Na + /K + -ATPase in different intestinal segments of the Lonchura striata and the Copsychus saularis was different. The vitality of Na + /K + -ATPase in the Lonchura striata was significantly higher than that of the Copsychus saularis. It can be concluded that the digestion and absorption capacity of Copsychus saularis and Lonchura striata are significantly different, and the reason may be due to their different diets and intestinal floras.

“…The reasons may be related to two aspects: one refers to the different gender division of labor. Males need to undertake the tasks of foraging and defense with more flight activities (Huang et al, 2020). On the other hand, the levels of sex hormones are different in different genders.…”

“…There are differences in feeding habits and habits between the two birds. Lonchura striata belongs to herbivore and feeds on plant seeds, especially on rice (Huang et al, 2020;Karasov, 1996) and Copsychus saularis mainly feeds on fruits and insects, with different food types due to seasons (Barnea et al, 1991;Yuan and Yan, 2016). The difference in the characteristics of the muscle fibers of two birds may conform to the differences in the living habits.…”

Background: Bird is important in maintaining biodiversity and its lifestyles and behaviors will pose an important impact on the ecological environment. Birds are also inseparable for ecological stability. Birds’ movement and living habits are a widely studied topic. Methods: Two economic valuable birds, Lonchura striata and Copsychus saularis, were selected in this study. It aims at investigating the characteristics of muscle fiber tissues and comparing the differences between male and female species. Histological techniques were used to determine the characteristics of the muscle fiber (diameter, area and density) in leg and pectoral muscles. Result: There were differences in the muscle fiber characteristics of the Lonchura striata and the Copsychus saularis. The characteristics of muscle fibers between males and females of the same species were significantly different and there were also significant differences in the same parts of different species. The diameter and area of muscle fibers are correlated to the density of muscle fibers. This study suggested that the characteristics of muscle fibers are related to their living habits and population characteristics.
