From Bruce Denness, Whitwell, Isle of Wight, UK
Simon Carter wonders whether there may be a relationship between the shape of birds' eggs and the nature of the nest in which they are laid (Letters, 29 July). Pigeons get this wrong by laying a smooth egg with pointy ends in a nest consisting of a few poorly selected twigs. It is not uncommon to find broken pigeon eggs on the ground beneath. They would be better advised to lay a non-slippery egg with sharp corners – a cube or pyramid perhaps – that would catch on the sides of the open lattice. But for the sake of comfort, the delivery process may require attention.
