Glossy Ibis Marloes Mere

The 3 Ibises have always been three, always flying together, feeding together, last night they were all together. This morning, they were 2 + 1. One was on it`s own feeding in front of the white cottage, the other two were flying around briefly in front of the Britton hide. I`ve always wondered if they were a breeding pair with a sibling from last season - although my views are only speculative, could they be about to head South? Bob Haycock`s link last week, showed that they make rapid progress in a short space of time. Or could they just stay? Again I`m only speculating..... we shall see.
