“But the music of the spring-tide is past; the cuckoo is no longer vocal; the dawn-chorus is silent; summer has stilled the voices that but lately trilled so tirelessly, and, until another spring⟳ arrives, hedgerow and spinney will not again resound with the singing of the birds.”

“[I]t was a poor woodcock year in the South of England; that young starlings were nearly fledged on the 25h January 1913; that the dawn choruses in March⟳ and up to the 10th April were very short, five to ten minutes only; the killing East and South wind and bitter cold effectually preventing, and generally that song was short and weak.”

“Woodland Birds takes one through the year in our broad-leafed woodlands and many of the very well-known voices of the habitat are beautifully recorded, the dawn choruses of the various spring⟳ months being exceptionally interesting.”

“[T]he hadada is a sort⟳ of ibis – a large brown bird with long legs, a long curved beak and a loud voice. Hadadas roost in numbers among the trees in the leafier parts of Nairobi and their eponymous call⟳ is one of the more insistent elements of the dawn chorus in that part of the world, though they may be heard at any time of the day.”

“Staying just under a mile from Gillingham station, I was up before the dawn chorus and parked at the station car park⟳ (£5.20 all day) in time for that 0456.”

“[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.”

“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 […]”

“The frequency spectrum (Fig. 1) includes micropulsations (Pₜ, P_c, LP_c, PP, SIP, IPDP), gyromagnetic resonances, Schumann resonance, solar whistlers[…], dawn chorus, hiss, whistlers and sferics.”

“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.”

“Alvin Lucier's (US) Sferics (1980) is a recording ot electromagnetic "tweaks," "bonks," and "swishes" originating in the ionosphere, the result⟳ of self-immolating meteorites, the dawn chorus, and the Aurora Borealis.”
