It means that they start a new friendship or they love each other...Sometimes you see birds do that almost everyday!
Since all existing birds, unless injured, each have two wings and one beak, the ratio of wings to beaks in a flock would be 2:1.
their claws and their beaks are their main adaptations? their claws and their beaks are their main adaptations?
Birds can differ from each other in many ways. Different species differ in both size and appearance along with instincts and ways. Birds of the same species can differ from each other just the same way as humans. E.g each person is different in their own way due to attitude, colour and thought. It's exactly the same. Many birds have hooked beaks, many have beaks for siphoning water and others have beaks for catching insects. Their diet varies beyond group species as do their appearance. Many birds may look the same but they each differ in thought, language, colour, size and diet.
1:2, there's one beak for each pair of wings.

bite each others bumss holes and bite their little ball bags
A bird's beak is evolved for the sort of food the bird eats. For example, birds who eat hard seeds have strong beaks to crack them open. Birds who drink flower nectar have long skinny beaks to fit inside the flowers.
I believe the main one was quite simply birds. When Charles Darwin went on an expedition he seen all the various exotic birds and noted how each of them were alike but also different, the main differences of all of them was their beaks. Some had strong beaks perfect for eating nuts and other various things, whereas others had sharp beaks designed for eating the pests. (Insects, Bugs etc.) Also the other main theory is by simply looking at human skeletons and how they have developed over the years which I am sure doesn't need an explanation as it is so widely seen.
not all birds like the Pelican and a Arctic Seal would not last in each others habitats, And a Penguin and a Pig would not last in each others habitats.
