The Blue Footed Booby

In the blue footed booby females will lay two eggs. So they'll mate with male, and then about 36 hours later, they'll lay the first egg. Then another three days later,they'll lay the second one. It almost always works out this way. And so researchers manipulated the system of the blue footing booby females to make them more fertile by painting their feet dark gray. Lo and behold, the second egg came along with fewer nutrients, fewer hormons. Mum provisioned the egg according to the fact that dad was no longer a high quality. Isn't that just an incredible demonstration of the ability that she has to alocate at such an early level of development
