Abstract: 

The Shikra (Accipiter badius) is a common raptor found in Aceh, Indonesia, with both resident and migratory populations. This paper explores the distribution, behavior, and characteristics of resident and migratory Shikra in Aceh, highlighting their adaptability and habitat preferences. Through a comprehensive analysis, we aim to elucidate the differences between resident and migratory Shikra populations in Aceh, providing valuable insights into their ecology and conservation.

Introduction: 

The Shikra, a small but adaptable raptor, is a familiar sight in Aceh, where it is found in both resident and migratory forms. Understanding the behavior and ecology of these populations is crucial for effective conservation efforts. This paper examines the distribution, behavior, and distinguishing features of resident and migratory Shikra in Aceh, shedding light on their role in local ecosystems and the challenges they face.

Distribution and Habitat Preferences: 

Resident Shikra in Aceh are commonly found along the coast, in lowland areas, and even in urban environments. They often utilize coconut trees for nesting in urban areas and display solitary behavior, although breeding pairs may be observed during the breeding season. In contrast, migratory Shikra may be more transient in their distribution, passing through Aceh during migration periods.

Behavior and Adaptability: 

Both resident and migratory Shikra exhibit remarkable adaptability, with the ability to thrive in diverse habitats ranging from coastal areas to urban environments. They are skilled hunters, preying on small birds, mammals, and insects, and may occasionally be seen soaring over urban landscapes in search of prey. Despite their adaptability, both populations may face threats such as habitat loss, pollution, and human disturbance.

Distinguishing Characteristics: 

Distinguishing between resident and migratory Shikra in Aceh can be challenging, especially for inexperienced observers. However, several characteristics can help differentiate between the two populations. Migratory Shikra may exhibit different plumage patterns or markings indicative of their migratory status. Additionally, their behavior, such as the timing of arrival and departure, can provide clues to their migratory nature.

Conservation Implications: 

Understanding the differences between resident and migratory Shikra populations in Aceh is essential for conservation planning and management. Conservation efforts should focus on protecting key habitats, minimizing human disturbance, and raising awareness about the importance of raptor conservation. Additionally, research into the migration patterns and threats facing migratory Shikra can inform targeted conservation strategies.

Conclusion: 

The Shikra, both resident and migratory, plays a vital role in the ecosystems of Aceh. By understanding their distribution, behavior, and distinguishing characteristics, we can better appreciate and conserve these fascinating raptors. Continued research and conservation efforts are needed to ensure the long-term survival of Shikra populations in Aceh and beyond.
