In Spanish, we have two verbs "to be" and two verbs "to have". These verbs are "ser" and "estar" and "tener" and "haber". We use verb "ser" to talk about features/characteristics or the action of being something, and "estar" to talk about the localization of something/someone, to talk about temporary states, and sometimes, to say "to reach". Try to describe the parrot writing sentences using the verb "ser" and try to write sentences using the verb "estar" to state where the parrot could be located or things that the parrot do temporarily. "Tener" is used to talk about possessions, so, try to write a sentence talking about features/characteristics or things that a parrot may possess. "Haber" is just used to talk about the existence of something in certain space regardless of its' location, and it has an impersonal form which is "hay". Where can you find parrots? Try to write a sentence using the "hay" impersonal form of the verb haber.
