Disclaimer: I don't know how good jalapenos are for macaws, or any other bird specifically. What I do know is that birds seem to lack the capsaicin receptor; birds which eat peppers will happily consume habaneros or scotch bonnets with no ill effects.
You can eat it but the one that you should eat is the naga jolokia which is very similar to jalapenos.

No Aztecs never ate Jalapenos, they were never part of their diet.
It is not recommended to eat jalapenos that have turned black as they may be spoiled and could cause food poisoning.
Usually you just eat them.
