Abstract

The term "migration" refers to the seasonal tendency to relocate. Numerous avian species exhibit this behaviour along a flyway that connects their breeding grounds to their wintering grounds and vice versa all over the globe. This is because migratory birds are very sensitive to even minute shifts in water level, which may be influenced by factors such as flooding or drought on the areas where they nest and spend the winter. In addition to being an essential habitat for migratory and resident birds, wetland habitats are also crucial for the activities of foraging, roosting, and nesting. Wetlands are an important habitat for many sorts of water-dependent birds. While the wetland satisfies the need for water for the agricultural land that is located in the surrounding area, it also serves as a location for the production of food and as a breeding place for a variety of migratory bird species and local inhabitants. Between the months of October and late February, a significant number of birds make their annual migration in the United States.

The current study, which was conducted over the course of two years, uncovered a total of twenty-one species of migratory birds belonging to six orders and twelve families. Between October 2022 and January 2023, as well as between October 2023 and January 2024. The Anatidae family has the most number of species on the list, with seven, followed by the Motacillidae family, which had three species. With two species, the Threskiorthidae family, and the other nine families, each with one species. The current analysis revealed that some species of birds were classified as Local Migrants (LM), while other species were classified as Summer Migrants (SM), and the other species were classified as Winter Migrants (WM).
