@UCB_CSSL Nothing in that link indicates that it is the evaporation that causes the wind; it mentions shear, which I understood was caused by surrounding air entraining with the precip. high in the atmosphere as a result of the no-slip condition

@UCB_CSSL Hi, are you sure about that physics? H2O (molecular weight of 18) is substantially lighter than N2 or O2 (28, 32 respectively), and thus humid air is actually less dense than dry air. I question whether the relative humidity creates the wind (yes cooling with increase density)

@IBIS_journal The paper's title is inaccurate: they only looked at vocalizations, they did not include non-vocal sounds in their 'global' analysis

This is Katie Johnson's 3rd and final dissertation chapter. We appreciate funding from @AnimBehSociety and I wouldn't mind doing more song learning experiments on these guys, with the right student or collaborator
