Morphological measurements.

<p>Morphological measurements of bats used to calculate obstacle spacing and feeding volumes. Body mass, forearm length, and wingspan (derived from 0.68 times forearm length) measurements are ± S.D. n  =  sample size.</p

Mean flight times through obstacle course.

<p>Comparison of mean flight times (sec ± SE) through an obstacle course by phyllostomids fed 1.5% alcohol and those fed a sugar water control.</p

Estimated origin of the farthest migrant.

<p>The bat with the δD_{furactual-predict} value suggesting that it had migrated the farthest from its latitude of fur growth also had a δD_fur value indicating that it was from the most northern location (collection site indicated by black circle). It likely originated at a location where the mean growing season δD_precip composition was between −63 and −74‰ (the area shaded in grey). The lettered points indicate the existing most northern records of <i>Perimyotis subflavus</i> (A = <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0031419#pone.0031419-Knowles1" target="_blank">[60]</a>; B = <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0031419#pone.0031419-Fenton1" target="_blank">[2]</a>; C = <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0031419#pone.0031419-Broders1" target="_blank">[65]</a>).
