Transcript of Superb Lyrebird
was taking her usual morning stroll with
her baby. Suddenly a Tasmanian Devil came
out of the bush and savagely attacked her:
her baby went running away into the forest.
When the Tasmanian Devil was done, all that
was left was a little piece of her beak. 2 days later a hiker found her and brought her into our lab, that is why we are here now!!! The Superb Lyrebird's diet
consist of small invertabrates
like worms, centipedes spiders
and he will very rarely
eat seeds. Fun Facts -Pair for life
-Live for 20 years or more.
-Appear on Australian 10 cent coin.
-They are shy and rarely appear in the wild.

All Colour Book of Birds Scientific Part Hypothesis: If we build a prosthetic beak for a Superb Lyrebird that is small enough then we will have more control over the beak and will be able to pick up at least 7 food items in 30 seconds because with a smaller beak, we have less to control. Purpose: To build a new prosthetic beak so that the bird can eat and pick up many things in 30 seconds, efficiently. Story (Problem) Problem #1: The regular tissue that we used
for the hinge broke. Modification #1: Modification #2: Did it work? Did it work? Problem # 2: We took off the tissue and replaced with a better fiber glass tissue and carpenter's glue. This worked because the tissue is much stronger than the last. The beak had to close. We put a lead fishing weight on another string attached to the lower beak. It worked because this beak would force down the movable lower beak.

Listening!! :) Conclusion: During the trials we did, we discovered that our beak
worked very efficiently. It was able to pick up a new food
item about every 2 seconds. The beak always picked up at least
7 items per trial. We picked up at most 12 items which is far more
than we expected. With all of this data, we are forced to accept our
hypothesis which stated that we would have plenty of control over our beak
and that we would be able to pick up over 7 items per trial. 7.75 10.75 10.5 Fungi Sun Producer Primary Consumer Secondary Consumer Tertiary Consumer Decomposer Fungi Beetles Physical Description -0.975 kg

-sings 30 min before sunrise
-Flexible toes to turn over sheets of bark.
-Female has less color than male to camouflage when in her nest.
-The beak is thin and pointy to pick bugs out of bark. Problem #3 We couldn't hold the head
and beak up without the
feathers falling off of it. Modification #3 We added a cardboard pole to
the bottom of the head and glued
it on with some construcion glue. Did it work? It helped alot and it
made the beak much easier
to test with. Problem #4 The bird needed nostrils. Modification #4 We carved into both sides
of the beak with a simple
steak knife. Did it work? Yes, it made the bird
look more real. Physical and Behavioural Adaptations Thanks for Watching :) Bugs Bugs Bugs
