Fancy French word to say that the olives are changing color. Turning from green to yellow green to purple, and eventually black. It is a magical time in the orchard where the olives become more and more visible.
I had never seen this before. A natural hive against the side of an oak tree. The bees are doing fine - may be they got attracted by a crack in the bark (see on top of the picture below). Supposedly bees like a 1/4 inch slit opening to their hive to settle there.
