Answer 1

Thinner, more pointed beaks allowed insects to be caught more easily

Step-by-step explanation:

Birds with thin, long, pointed beaks usually consume insects. This is because the beak is great for finding worms in soil (sifting and probing around), exploring inside the bark of trees, and fitting into other holes where insects might live. This allows them to exploit insects as a diet resource. A thicker beak would be better for strength such as cracking nuts and seeds.
