Cover A pair of kookaburra nestlings, 35 days after hatching. As is usual in kookaburra broods, the male (on the right) hatched first; his sister hatched later. The third-hatched sibling (another male) was killed within two days of hatching by its older siblings. See Legge et al., pp. 524-533. Photo by Sarah Legge.
