1899. Ovenbirds were rising and singing over the woods in all 
May 21. directions as I crossed Benson* s field shortly after sunset. 
One continued his song during the whole of his descent al- 
though he shot down along a steep incline and at tremendous 
'speed. How can a bird emit loud vocal sounds under such con- 
ditions? One would suppose that if he merely opened his 
mouth his breath would be driven down his throat.
