Bird breeds refer to the various types of birds that have been selectively bred for specific traits, such as size, color, or behavior. These breeds can be found in both domestic and wild species. For example, pigeons have numerous breeds, each with unique characteristics, while chickens are bred for meat or egg production. In the wild, bird breeds are often categorized into species based on their genetic similarities and differences. Finches, sparrows, and eagles are examples of wild bird species that exhibit a range of breeds adapted to their environments. Understanding these breeds helps in conservation efforts and birdwatching activities.
