Step-by-Step Explanation
Step 1: Introduction to Bird Migration
Many bird species travel long distances annually in response to seasonal changes in temperature and food availability. This phenomenon, known as migration, helps birds find more suitable habitats for feeding and breeding.
Step 2: Understanding the Context of the Question
The question compares humans shifting from Delhi to Shimla during summer heat to migratory birds leaving cold regions (like Siberia) to find warmer and more hospitable environments. Among the listed options, they travel to a specific national park in India.
Step 3: Keoladeo National Park (Bharatpur Bird Sanctuary)
1. Location: Keoladeo National Park is situated in Bharatpur, Rajasthan, and is well-known for its wide variety of bird species.
2. Ideal Habitat for Birds: This park provides abundant food resources and suitable wetland habitats, especially during cooler months when wetlands in Siberia freeze and food becomes scarce.
3. Peak Season for Migratory Birds: The migratory season typically begins around October/November and continues until March. During this period, numerous species, including the famous Siberian Crane, can be observed in large numbers.
Step 4: Why Keoladeo National Park is the Correct Option
Of the given choices, Keoladeo National Park stands out as a globally acclaimed bird sanctuary that hosts thousands of migratory birds escaping harsh winter conditions in the north. Corbett National Park and other mentioned options do attract wildlife but are not as renowned for hosting large congregations of migratory birds from Siberia as Keoladeo National Park is.
Conclusion
Therefore, just like people moving to cooler regions to escape extreme heat around Delhi, migratory birds from Siberia and other cold regions seek out warmer environments with plentiful food in India. Keoladeo National Park offers the perfect refuge, making it the correct answer.
