The study assumes that the animals incubating the eggs were their parents - 
which may not necessarily be the case. 

Magpie geese here in Australia raise their goslings in threes instead of in 
pairs; the parents of the eggs, and one of their offspring from the previous 
year. I don't know whether big sister or brother also helps incubate the 
eggs, but they certainly help to care for the hatchlings. Since magpie geese 
share their swamps with crocodiles, it seems that having three pairs of eyes 
looking out for trouble is better than two.
