Can birds taste the hotness of mustard oils?

r/

I know that they don’t get irritated by capsaicin, but do they react to mustard oils at all?

I can’t find anything about it online except that they are allowed to eat mustard seeds.

    Oh wow something I might be helpful with (flavor chemist here). So mustard spiciness (also wasabi, horse radish) are caused by isothiocyanates. There is some evidence that birds have a bad reaction to it, but only if eaten too much. So I’m not sure if that has to do with the spicy or some other complication.
