  • Abstract Fieldfares ( Turdus pilaris ), which nest solitarily as well as in colonies, offer an opportunity to assess within one species the relative advantages of clumping versus spacing out. An experiment with artificial, egg-baited nests showed that predation in the absence of fieldfares was higher on clumped than on scattered nests. In another experiment, we tested whether artificial nests run a higher risk of predation near solitary fieldfare pairs than near fieldfare colonies. Nest… CONTINUE READING
