A. on account of its feeding and nesting "on account if its" is unidiomatic
B. on account of their feeding and nesting THEIR is plural. Should be singular since it refers to the Amazonian Biffa. Moreover, if THEIR is used, it refers to "Ornithologists" which is plural.
C. because it feeds and nests Correct
D. because they feed and nest THEY is used here. Same issue as B
E. because of their feeding and nesting Same issue as B
