Background: The liver is a vital organ in avian species, particularly in raptors like falcons, where metabolic demands are exceptionally high due to their predatory lifestyle and flight requirements. Understanding the histological architecture of falcon liver provides insights into their physiological adaptations and metabolic capabilities.

Objective: This study aimed to investigate the microscopic anatomy and cellular organization of the liver gland in falcon fowl using various histological staining techniques.

Methods: Liver samples were obtained from adult falcons and processed using standard histological techniques. Sections were stained with Hematoxylin and Eosin (H&E), Masson's trichrome, and Periodic Acid-Schiff (PAS) stains to evaluate cellular morphology, connective tissue distribution, and glycogen content respectively.

Results: The falcon liver demonstrated typical avian hepatic architecture with distinct hepatocytes arranged in hepatic cords. Hepatocytes showed abundant cytoplasm with prominent nuclei and extensive glycogen storage. Masson's trichrome revealed minimal connective tissue framework, while PAS staining confirmed significant glycogen deposits throughout hepatocytes.

Conclusion: The histological features of falcon liver reflect adaptations for high metabolic activity, with enlarged hepatocytes and extensive glycogen storage supporting the energy demands of flight and predatory behavior.
