How can I change the name of the legend from "colour" to "population"?

Legend doesn't appear automatically

I have a problem with my code. I used what you taught in this video and added this: +scale_color_discrete(name="Legenda", labels=c("Nº de gaivotas adultas", "Nº de gaivotas juvenis", "Nº total de gaivotas")) to change the name of the tittle of the legend, but the colours I chose dissapeard and now it has the original automatic colours. How do I get the colours I want back??? Please help!

Can you create a video where we also change the shape of points and match them along with the legend?
