Body mass, wing measurements and optimal flight speeds in Glossophaga soricina antillarum

Bat	Body mass (g)	Wing span (m)	Wing loading (Nm⁻²)	Aspect ratio	V_mp(m s⁻¹)	V_mr(m s⁻¹)
Non-pregnant	10.2-11.4	0.273	8.8-8.9	6.6	P: 5.9-6.1	11.4-11.7
					R: 3.4	4.6-4.7
Pregnant	13.4	0.274	13.0	7.4	P: 6.4	12.0
					R: 3.9	5.2

The minimum power speed V_mp and maximum range speed V_mr were estimated with theoretical expressions by P(Pennycuick, 2001a) and R(Rayner, 1986).
