Abstract
Growth patterns of nestling Collared Doves Streptopetia decaocto, Woodpigeons Columba palumbus, Feral Pigeons C. livia and Stock Doves C. oenas, in Britain were compared. Open‐nesting Collared Doves and Woodpigeons left the nest at about 60% of adult weight, hole‐nesting Stock Doves at adult weight, and partial hole‐nesting Feral Pigeons at an intermediate stage. Other species of pigeons and doves studied to date also fit this pattern. Stock Dove nestlings reared in nest‐boxes reached heavier weights and left the nest later than those in more exposed sites. These results were correlated with differential predation pressure on open‐ versus hole‐nesting birds.
