Great sentence! It mostly works, but I have a small suggestion to make it clearer.
- Original sentence: The bowerbird makes its bower pretty to impress its lady.
- Small issue: The word "lady" is OK for people, but for birds it's clearer to say "a female" or "a mate" (or "a female bowerbird").
- Better verbs: Instead of "makes its bower pretty," you can say "decorates its bower" or "builds and decorates its bower." Those are clearer and a little more precise.
Corrected sentences you can use:
- The bowerbird decorates its bower to attract a mate.
- The bowerbird makes its bower pretty to attract a female bowerbird.
Step-by-step grammar check:
- Start with a capital letter: "The" — good!
- Subject: "The bowerbird" — who the sentence is about.
- Verb: "makes" or "decorates" — what the bird does.
- Object: "its bower" — what it makes or decorates.
- Purpose phrase: "to attract a mate" or "to impress a female bowerbird" — tells why it does it.
- End with a period: good.
Extra note: A "bower" is a special structure a male bowerbird builds and decorates to show to a female. Nice work — just swap "lady" for "female" or "mate" to be more accurate about birds.
