How do birds attack their prey?

Hawking is a feeding strategy that birds use to catch flying insects in the air. They fly out from a perch to snatch an insect and then return to the same or a different perch. Birds with flat, wide beaks are normally birds that catch flying insects.


If only one species is considered the fittest why do you still have so many variations among species Why do some birds have very long pointy beaks while other birds have short flat beaks?

It depends on their diet. If they are omnivors they have long pointy beaks to tear the meat up instead of teeth. If they are herbivorous they have short flat beaks for seed, vegetable and fruit eating.

It is not true that only one species is the fittest. 'Survival of the fittest' like many catchphrases, is a gross oversimplification. What happens is that some creatures are better fitted to some conditions than others. In a situation where there is only one ecological niche, it may come down to one characteristic's giving a survival advantage over another and therefore that characteristic may become predominant. For instance, if there is only one main source of food on a small island, the birds may all have similar adaptations to exploit it, e.g. large seeds can be cracked most easily by strong beaks. Most ecosystems are incredibly complex, however, and species evolve to exploit different parts of it. Long pointy beaks let the bird reach into inaccessible food sources, e.g. a curlew can get food from deep in the sand. Shorter, flatter beaks, e.g. on a duck, let them exploit different food sources such as organisms in shallow mud. Having different adaptations lets several species live close together without competing for the same food.
