Hummingbirds and Flowers

APES-GQWKG4

Over time, hummingbirds and bird-pollinated flowers have developed a mutualistic relationship. The flowers' color suits the birds' vision, their nectar is suited to the birds' diet and their unique flower shapes fit the bills of distinct hummingbird species. The bloom times of the flowers also coincide with hummingbirds' breeding seasons.

This is an example of

B

Allopatric speciation

C

Convergent evolution

D

E

Sympatric speciation
