Every year I lose most, if not all of my red Sarr flower buds and I think birds mistake them for red berries. The buds are snapped off cleanly and often still lying in the pot or nearby. But when I had S. flavas, their yellow buds were never bothered. That's why I think it must be birds, since this time of year they go for red fruit and don't bother with yellow. Dirty, disgusting, filthy, lice-ridden birds.
