In Spain where we tend to assign dramatic or religious (or both) names to many things, we call this plant 'Lagrimas de la Virgen Maria' Virgin Mary's Tears. The plant belongs to the same genus as onions and garlic.
I saw this bird yesterday evening in a flooded meadow close to Lluriach. According to Javier from Menorca Walking Birds, it might be a Glossy Ibis, which is rare in Menorca.
