Anatomical Structures of the Limb: Anatomical Structures of the Limb of White-nest Swiftlet (Aerodramus fuciphagus) and White-headed Munia (Lonchura maja)

Aerodramus Swiftlet are very fascinating. What is the most incredibly amazing about this particular type of bird is that they can make a nest from their own saliva. But, not everyone knows that Swiftlet generally, is unable to stand while perching. I discovered the answer when I compared major limb muscles between Swiftlet and White-headed munia to seek for their differences, anatomically and histologically.
