Understand Bird
Feathers identify the animal meaning even when the bird cannot fly; watching and identifying wild birds signals the verb meaning.
Flying does not define a bird—penguins and ostriches are birds. In British slang, bird for a woman can sound dated or disrespectful, and “the bird” can name a rude gesture, so avoid those uses.
Students compare picture cards of a bat, butterfly, penguin, and robin. They identify which are birds using feathers rather than flight, then write one noun sentence and one verb sentence with bird.
Compare “A penguin is a bird” and “We bird near the marsh.” What features prove the noun meaning, and what action does the verb name?
