I found a bird [ENG/ESP]

I was out for a walk and came across these birds. There were two of them. I don't know what they're called, but I'd like to find out. When I saw them, they looked very happy and peaceful. I don't know if birds can have worries (I suppose they can, they are living beings after all), but these ones didn't seem to have any. They almost blend in with the green surroundings, but there they are, and they are beautiful. I just took a couple of photos and left so they could continue to be at peace.

Estaba dando un paseo y me conseguí con esta ave, habían dos de ellas, no sé como se llaman me gustaría saberlo, al verlas las vi que estaban muy felices, pacíficas, no sé si un ave pueda tener preocupaciones (supongo que si, son seres vivientes después de todo) pero estas no las tenían, casi no se distinguen con lo verde del lugar pero ahí están, y son hermosas, solo tomé un par de fotos y me fui del lugar para que siguieran estando en paz.
