Where I can find a bird?
Birds can be found in a variety of environments including forests, deserts, grasslands, wetlands, and urban areas. Some common places to see birds include:

Parks and Gardens: City parks and botanical gardens often have a variety of bird species that visit for food and water.

Beaches and Coastal Areas: Seabirds, such as gulls and terns, can often be found along the coast and on beaches.

Wetlands: Marshes, swamps, and other wetlands are important habitats for waterfowl and other bird species.

Forested Areas: Forests provide habitat for a diverse range of bird species, including warblers, thrushes, and woodpeckers.

Bird Feeders: You can attract birds to your backyard by putting up a bird feeder and filling it with birdseed.

In addition to these places, many birds can also be observed while hiking, camping, or on nature walks. It's important to remember to observe birds from a distance and to not disturb their habitats.
I haven't seen birs in my urban area. There are only a few green spots like parks and gardens, but there are no birds? Is it possible, that birds only come out at night or are there other reasons, why I could not find birds so far?
