- Other birds: Parrots compete with other bird species for food sources like fruits, nuts, seeds, and insects. These competitors can include birds of prey, such as hawks and eagles, as well as smaller birds like finches and sparrows.
- Mammals: In certain regions, parrots compete with mammals like monkeys, squirrels, and bats for access to fruits, nuts, and other plant-based foods. Some mammals, such as wild cats and rodents, may also prey on parrot eggs and chicks.
- Insects: Insects, particularly ants, bees, and wasps, can compete with parrots for food sources such as fruit and honey. Some insects might infest or damage parrot nests and cause disturbances.
- Reptiles: In certain ecosystems, parrots may compete with reptiles, including snakes, lizards, and crocodiles, for food and nesting sites. Some raptors or larger reptiles might be predators of parrots or their eggs.
- Invasive species: Introduced, non-native species brought into habitats may become competitors or predators to native parrots. Examples include invasive bird species or rats in various environments.
- Other parrots: Even within the same parrot species or flocks, individuals might compete for access to specific food sources, mates, or preferred nesting sites during the breeding season.
The intensity and extent of competition vary depending on the environmental conditions, resource availability, and specific species interactions in a given ecosystem.
