Table 10. — data on hummingbirds and other birds 



FROM various AUTHORS 



The wing-beat rates given here for hummingbirds are believed to have higher 

 precision than those determined by Ruschi and Greenev^^alt using the portable 

 monocular stroboscope. They were determined either from high-speed moving 

 pictures or with stroboscopic methods of higher precision. 



M = High-speed moving pictures 

 S = Stroboscopic
