If no one is around, let me throw one in;

The beaks of pelicans have an adaption, shared with no other bird in the world. What is it?

They have a large flap of skin beneath their beaks, to handle all of the water that comes with the fish meal. They then let the water drain out and swallow their dinner.

The questions are too easy for you clever lot.

The pelican has a modified lower mandible with a huge, distensible pouch. The pouch is so large that, in addition to the bird's catch,it can hold almost 14 litres of water.

Marabou storks has an important adaptation for flight. What is it and why?

Hollow toe bones as they are so heavy? To help them stay in the air?

Heksie :gflower: , i will give it to you: In addition to hollow leg bones, Marabou storks have hollow toes to reduce their weight. In such a large bird, this is an important adaptation for flight.

The European cuckoo (Cuculus canorus) is, famously, a “brood parasite”: the female lays her eggs in other birds’ nests. Typical victims are small birds like reed warblers and wagtails. When the young cuckoo hatches, its first act is to dispose of any other eggs: it heaves them out of the nest, leaving itself as the sole occupant.
Also interesting: Among professional brood parasites, different species have different levels of destructiveness. The duck, for example, is rather charming: it doesn’t destroy any eggs nor enslave its foster parents. All it needs is a bit of warmth for the egg to incubate. The day the duckling hatches, it paddles off into the world, fending for itself right from the get-go. It’s one of the planet’s most independent young birds.
