Actually it depends on the toucan species. With most species the males and females have the same coloration, however it may still be possible to visually sex some despite this. Emerald toucanets for example have the same coloration regardless of gender, but there's some differences in size, and proportions that with practice make it possible to distinguish their genders visually with enough practice. However in the case of green aracaris and a few other species the males do have different coloration from females, and are quite easy to sex visually. I've never heard of a species of toucan where the male is actually more colorful than the female or vice versa however.

Yes, a little bit. The female is a little bit larger than the male, and the male is a brighter color.
The male peackocks have the adaptation of large feathers. They use such big feathers to atract peahens (female peacocks).
