Reddish brown poop?

[HollowedSoul331]

I have two lovebirds, they're extremely active today but one just passed reddish brown poop. I forgot to take a picture, but it's kinda a bit of red poops mixed with brown, not wholly red like some I've seen on the thread. Just wanna some advices since the little guy doesn't appear to have health issues, plus I did put a lot of red bell-peppers and carrots in his bowl today.

HIs poop was kinda like those mosiac picture. Brown and red pixels mixed together. I'm kinda confused.
