Population Dynamics of Avian Diversity in the District Okara, Pakistan

Pakistan has a varied bird fauna, with over 790 species recorded and their distribution in three zoogeographical zones (Oriental, Palearctic, and Ethiopian), which is exceptional in the world. The data on avian diversity and abundance in the district Okara, Punjab was carried out from January 2022 to January 2023. Data were collected by direct, indirect, and flocks count methods on four transect points used in the study by visiting the field and by interviewing the local people and hunters about the current and past status of the avian fauna of the area. Okara district contains a major wetland for both local and international migratory birds, including falcons, gulls, plovers, snipes, waders, and long-distance migrating birds. A total of 201 avian species of 19 orders and 54 families were recorded. These included 54 winter migrant species, 23 summer migrants, 13 passage migrants, 1 year-round visitor, and 110 resident species. The spotting of seven globally threatened species and three vulnerable also highlights the importance of this area for avian species. A total of 80 species were recorded in the Passeriformes order. The Shannon-Weiner diversity index showed that Transect Point 1 (H′ = 4.906) had the largest diversity of birds, followed by Transect Points 2, 3, and 1, i.e., 4.778, 4.672, and 4.679. Species evenness has varied among transects based on diversity, with values of 0.7266 (TP 1), 0.6719 (TP 2), 0.7082 (TP 3), and 0.7226. (TP 4). The Simpson index (1-D) for Transect Points 1, 2, 3, and 4 was 0.991, 0.9872, 0.9883, and 0.9888, indicating that Transect Points 1 and 2 had the maximum bird species diversity. The findings revealed that the Okara district is home to a large number of resident migratory and endangered bird species. As a result, it is critical to conserving its habitat as well as bird variety by overcoming serious challenges.
