"Bring it down now", I suggested to Adam. Time was very much of the essence as we needed to avoid this Little Grebe thinking that Adrian was its father. Most wildlife that Adrian has cared for becomes inprinted very rapidly - in the past this has included House Martin, Swallow, House Sparrow, 337 Canada Geese, a Ladybird (called 'Spot') and several clothes moths that simply wouldn't depart.
I phoned The Bearded One as he is rather partial to Little Grebes in the hand.
Eventually, after wandering round the lake, we located the nest under a weeping willow tree - we let it go. Later that evening the adults had returned to the area so hopefully 'Little Hagar' was reunited with Mum and Dad - ahhhh.
