* Mountain lions: These big cats are very solitary, except when mothers are raising cubs.
* Badgers: Badgers live in burrows, but they are solitary and don't typically interact outside of breeding season.
Birds:
* Owls: Many owl species are solitary, especially during nesting season.
* Hawks: Many hawk species are solitary hunters.
* Herons: Herons are solitary birds except during mating season.
Reptiles:

Keep in mind:
* Even animals considered solitary often interact with others for specific reasons, like breeding, raising young, or defending territory.
* There are many exceptions to these generalizations, and the social structure of any species can vary depending on location, resources, and other factors.
To get a better understanding of any specific animal's social habits, it's best to research their specific species and behavior.
