True or false:

There is a bird that uses the heat of volcanos to heat its eggs.
 
Those are all nests! :-D Seriously, I'll give an example of species that make these nests:

pendulous - Baltimore Oriole
pensile - Baltimore Oriole again
cup - American Redstart
cavity - Wood Duck, and almost all parrots species
platform - Mourning Dove
ground - Mallard

I guess maybe one isn't considered scientific, but all of them are used terms! :)
 

Incorrect. Pensile is the nest such as a vireo's, that is not supported on the bottom, but is held together by weaviing twigs and grasses through a Y in a branch.

"With birds, this describes a nest type in which a bag-like structure hangs well below the support branches, with the entrance usually at the top of the bag."
 
thats for the defenition of the word- not the bird nest.

pendulous hand down more and are long, pensile are more round and dont hang as much

Yes tim, all the english language comes from greek/latin roots, but you wouldnt ever hear someone latin saying "cup".

hmm... these days "cuppa" actually translates to a cup of coffee...
