Decide whether the sentence is grammatically correct or incorrect as written. Habían tres pájaros en el árbol.

The sentence is incorrect because haber is impersonal when it means “there is” or “there are,” so it stays singular even when the noun that follows is plural. The correct form is “Había tres pájaros en el árbol,” not “Habían tres pájaros.” Thus, the sentence is grammatically “Incorrect.”
