BRITAIN’S MOST INTRIGUING NESTS
1 GREAT CRESTED GREBE
Grebes nest at the edges of lakes and in the quiet backwaters of canals. Each pair fashions a floating heap of waterweed and pieces of reed or sedge, anchored to reeds or other vegetation. The birds add to the untidy muddy structure over the breeding season, often incorporating bits of rubbish. Should the water level rise or fall, the nest will generally move with it, saving the precious eggs.
