Some Australian birds of prey in arid areas will only breed once every ten 
years or so (whenever 
the rains come, and result in rat eruptions). I seem to recall that some 
species of shore birds 
(oyster catchers I think) only breed when Lake Eyre fills with water (by the 
same rains that allow 
the raptors to breed).
