My comment:
(a) The paper:
Alejandro Rico-Guevara1 and Margaret A. Rubega, The hummingbird tongue is a

print May 2, 2011, doi:10.1073/pnas.1016944108
http://www.pnas.org/content/early/2011/04/27/1016944108.abstrac
(b) It is hard to comprehend if one can not read the full text of the paper,
which full of photos and illustrations and which is available to

However, the illustration, copied from the paper, may be helpful.
