Barcelona Cathedral has geese in the cloister, they are connected with St Eulalia whose relics are in the confessio below the High Altar. I suspect originally they honoured the Canons on her feast day.
Though so many of the clergy were martyred during the Civil War the interior of the Cathedral was spared, being in the hands of the Communists rather than Anarchist.
I hadn't realised St Raymond of Penafort is a resident. Nice to meet unexpected Saints, especially if they share your name.
