Next message: Shelley and Steven Welchner: "Callenge Question #7"
Here is our answer for #5
Challenge Question #5:
"Hummingbirds build their nests out of lichens, bud scales, thistle and dandelion down, and spider silk. How many reasons can you list as to why these materials are perfect for hummer nests?"
These materials would be good because they provide warmth.
The spider silk is sticky to hold the nest together.
Soft down provides coziness.
