"most known" should be corrected to "best known."

• Explanation: The correct phrase is "best known" when describing what someone is most famous for. "Most known" is not idiomatic in English.

"can be able" should be corrected to "can."

• Explanation: "Can be able" is redundant. The correct form is simply "can," as "can" already indicates ability.

"with a large number of which" should be corrected to "with a large number of them."

• Explanation: The phrase "which" is incorrect here because it refers to the noun "species," but in this context, "them" should be used to refer back to "species of birds."

"their" should be corrected to "its."

• Explanation: The word "their" is plural, but it should be "its" because the subject "a seed" is singular. The sentence should maintain subject-verb agreement.
