SHOWING LAUGHING GULLS ON THEIR NESTS IN THE DISTANCE The Bird-Life of Cobbs Island 113 itself nearly invisible on a bit of sand, where there is no object with whichit might be confused, is especially striking. In the newly hatched young themandibles are of equal length and the characteristic prolonged lower man-dible does not appear to be fully grown until after the bird takes may be considered as evidence that this specialized character has beendeveloped late in the history of the species, or it may be a correlation ingrowth which defers the perfection of an organ until it can be successfullyemployed.
