2. Darwin’s Finches adaptations
Darwin's finches are an excellent example of the way in which species' gene pools adapt for long term survival. Their beaks have evolved over time to be best suited to an important function—Food Acquisition

3. Adaptation: a characteristic of a species that allows members of that species to survive in a particular environment

4. Beak Adaptations Pelican
Pouch like — can hold the fish it catches to eat

5. Avocet
Long thin – can probe shallow water and mud for the
insects it eats.

6. Pointed – can break and probe bark of trees for the insects it eats
Woodpecker
Pointed – can break and probe bark of trees for the
insects it eats

7. Hawk
Curved – can tear solid tissue for the meat it eats

8. Warbler Finch
Short, Stout – Can crack the seeds and nuts it eats

9. Hummingbird
Slender, long – Can probe the flowers for nectar

10. Feet
Duck
Webbed – Aids in walking on slick rocks and
swimming

11. Crane Heron
Long toes – Aids in walking in mud

12. Clawed – Can grasp food when hunting prey
Bald Eagle
Clawed – Can grasp food when hunting prey

13. Chicken
Grasping – Aid in sitting on ledges, roosting, and
good protection

14. Legs
Ostrich
Long, Powerful – Aids running ability

15. Great Blue Heron
Long, Slender – Aids wading ability

16. Bald Eagle
Powerful Muscles – Aids lifting, carrying prey

17. Chickens
Flexor tendons – Aids in perching, grasping

18. Wings Peregrine Falcon
Large Wingspan – Aids soaring ability while hunting

19. Hummingbird
Small, fast wings -- Ability to hover near food source for maneuverability and quick getaway

20. Objectives in Lab
You will recognize that there are advantages for birds in looking the way that they do.
You will recognize some of the ways in which birds are physically adapted to their environments
Follow instructions given on lab sheet to construct a new species of bird perfectly adapted with characteristics from its evolutionary gene pool to not just survive, but thrive!!
