Honey Creepers are Invasive Species

What is left

There are 56 different types of species of the Hawaiian Honey Creepers known to exist. 18 of which are endangered, and 38 as extinct. One example would be the endangered Palilas.

Genetic Drift, Natural Selection,

Gene Flow

Hawaiian Honey Creepers are invasive species due to weather related factors like climate changes. Scientists believe that closely related family of the finches came to the Hawaii islands from the Galapagos which resulted into evolution and natural selection

They all contribute to adaptive radiation in Hawaiian Honey Creepers because of how the numerous variations in the Honey Creepers. The have adapted to survive in the Hawaiian Islands and their variables such as being surrounded by water. It resulted in finches with various types of beaks to specialize in different traits and tasks.

The Hawaiian Honey creeper is a Hawaiian song bird with bright red feathers and long curved beaks that has several variations in which some are specialized to their own traits.

Conserve the Honeycreepers!

Diversity

Changes & Adaptations

There are at least 56 different species of the Hawaiian Honey creeper known to have existed.

• Based on specific food sources, it made the finch to adapt to the habitat which led to to natural selection & the evolution of different types of species and beaks of the finches.

Ancestors

The original ancestor would be the Eurasian Rosefinch. It colonized to create various types of species of finches.

• Thicker, stronger beaks for seed-eating birds

A process when a single species or a small group of species evolves into several different forms living in different ways.

• Long beaks for nectar-eating birds

• Beaks like swords for insect-eating birds

Hawaiian Honey Creeper

There are at least 28 living species and 17 fossil species of birds. They have all evolved from single species in the past on the Hawaiian Islands.
