dawn chorus

/dɔːn ˈkɔːɹəs/

[T]he dawn chorus usually has a characteristic chirpy sound, but at times changes into a hiss not unlike tube noise. […] Several investigators, including the author, have at times noticed a tendency for the dawn chorus to change intensity for a short period immediately following some lightning strokes. This may indicate a change in propagation conditions due to the electromagnetic or ionization effect of the strokes.

1956 September 14, Harold E. Dinger, “The Dawn Chorus”, in Whistling Atmospherics (NRL Report; 4825), Washington, D.C.: Naval Research Laboratory, →OCLC, page 14:

It is known that chorus, or ‘dawn chorus’, exhibits a pronounced diurnal variation in its occurrence and that different stations show different local times for the diurnal maxima. These maxima have been shown to be a function of geomagnetic latitude […]

1960 January 9, Joseph H. Pope, “Effect of Latitude on Diurnal Maximum of ‘Dawn Chorus’”, in Nature: A Weekly Journal of Science, volume 185, number 4706, London: Macmillan and Co.; New York, N.Y.: St. Martin’s Press, →OCLC, page 87, column 1:

Both authors used data from other stations to show that the time of maximum dawn chorus activity increased with geomagnetic latitude. [G. McK.] Allcock argued that this characteristic could be related to the precipitation of positively charged solar particles that might produce the dawn chorus by exciting proton plasma oscillations in the outer ionosphere. These oscillations would then reach the earth in the whistler mode.
