Pengaruh Urbanisasi terhadap Populasi Burung Gereja: Studi Kasus di Kota Bandung

The bustling city of Bandung, with its vibrant culture and rapid development, presents a fascinating case study for understanding the impact of urbanization on wildlife, particularly the ubiquitous House Sparrow (Passer domesticus), commonly known as the Church Sparrow. This study delves into the intricate relationship between urbanization and the population dynamics of Church Sparrows in Bandung, exploring the factors that influence their presence and abundance in the city's diverse landscapes.

Urbanization and Habitat Modification

Urbanization, a defining characteristic of modern societies, profoundly alters the natural environment, leading to habitat fragmentation, loss of green spaces, and the introduction of novel structures and materials. These changes have a significant impact on the availability of resources for Church Sparrows, influencing their population dynamics. In Bandung, the rapid expansion of concrete jungles has resulted in the decline of traditional nesting sites, such as tree cavities and hedgerows, which are essential for breeding and raising young. The replacement of natural vegetation with buildings and paved surfaces has also reduced the availability of foraging grounds, limiting access to seeds, insects, and other food sources.

Food Availability and Competition

The availability of food is a crucial factor determining the success of any bird species, and Church Sparrows are no exception. In urban environments, food sources are often concentrated in specific areas, such as parks, gardens, and food stalls. This can lead to increased competition for resources, particularly during periods of food scarcity. In Bandung, the presence of other bird species, such as pigeons and starlings, further intensifies competition for food, potentially impacting the population size of Church Sparrows.

Human-Bird Interactions

Urbanization also brings about a unique set of interactions between humans and birds. Church Sparrows, being adaptable and opportunistic, have learned to exploit human-modified environments, often foraging in garbage dumps and feeding on scraps discarded by humans. However, these interactions can also be detrimental, as birds may be exposed to pollutants, diseases, and even intentional harm. In Bandung, the use of pesticides and the presence of feral cats pose significant threats to Church Sparrow populations.

Conservation Implications

Understanding the impact of urbanization on Church Sparrows is crucial for developing effective conservation strategies. In Bandung, efforts to mitigate the negative effects of urbanization on Church Sparrow populations should focus on creating and maintaining suitable habitats, such as green spaces and parks with native vegetation. Providing supplementary food sources, particularly during periods of food scarcity, can also help to support their populations. Additionally, raising awareness about the importance of bird conservation and promoting responsible human-bird interactions can contribute to the long-term survival of Church Sparrows in urban environments.

The study of Church Sparrows in Bandung highlights the complex interplay between urbanization and wildlife. While urbanization presents challenges for these birds, their adaptability and resilience allow them to persist in urban environments. By understanding the factors that influence their population dynamics, we can develop effective conservation strategies to ensure the continued presence of these fascinating creatures in our cities.
