| 1. What are the basic characteristics of birds? |  |
Ans.Birds are warm-blooded vertebrates that belong to the class Aves. They have feathers, wings, and beaks, which are adaptations that help them fly and live in various environments. Most birds can fly, though some species, like ostriches and penguins, cannot. Birds lay eggs and exhibit a wide variety of colors and sizes.
| 2. How do birds help the environment? | |
Ans.Birds play a crucial role in maintaining ecological balance. They help control insect populations, pollinate plants, and disperse seeds, contributing to plant reproduction. Their presence indicates a healthy ecosystem, and they can also help in controlling pests that may harm crops.
| 3. What do birds eat? | |
Ans.Birds have diverse diets depending on their species. Some are herbivores and primarily eat seeds, fruits, and nectar, while others are carnivores and hunt for insects, small mammals, or fish. Omnivorous birds consume a mix of both plant and animal matter. Each bird species has specific feeding habits that suit their habitat and lifestyle.
| 4. Why do birds migrate? | |
Ans.Birds migrate to find better living conditions, such as warmer climates during winter months or abundant food sources during breeding seasons. Migration helps them avoid harsh weather and ensures their survival and reproduction. Many species travel long distances, often returning to the same places each year.
| 5. How can we attract birds to our backyard? | |
Ans.To attract birds to your backyard, you can provide food, water, and shelter. Setting up bird feeders with seeds, offering fresh water sources, and planting native trees and shrubs can create a welcoming environment. Additionally, avoiding the use of pesticides and providing nesting boxes can further encourage birds to visit your garden.
