My comment:
(a) The paper:

Alejandro Rico-Guevara1 and Margaret A. Rubega, The hummingbird tongue is a fluid trap, not a capillary tube. Proc Nat Acad Sci, published ahead of print May 2, 2011, doi:10.1073/pnas.1016944108

(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 subscribers only.

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