1.Helped broods receive more prey items and the breeding male, but not female, at helped nests delivers food at lower rate than at unhelped nests.

 

2.In 1086-1991, 35% of first nesting attempts for the year in any burrow (n=467) failed. In most cases where the cause of nest failure was known it was the result of predation, usually ladder snakes and sometimes Montpellier snakes or weasels.

 

See!!! predation prevails in the colony, and male breeders show compensatorily feeding!!!
