      But the music of the spring-tide is past; the cuckoo is no longer vocal; thedawn-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.
    • 1914, W. Parkinson Curtis, “Phenological Report on First Appearances of Birds, Insects, &c., andf First Flowering of Plants in Dorset during 1913”, in Henry Symonds, editor,Proceedings of the Dorset Natural History and Antiquarian Field Club, volume XXXV, Dorchester, Dorset: […] Dorset County Chronicle office,→OCLC,page195:
      [I]t was a poor woodcock year in the South of England; that young starlings were nearly fledged on the 25h January 1913; that thedawn 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.
    • 1971 July–September, “Book Reviews”, in W. A. Sledge, editor,The Naturalist: A Quarterly Journal Principally for the North of England, number918, Leeds, Yorkshire:Yorkshire Naturalists’ Union,→ISSN,→OCLC,page116:
      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, thedawn choruses of the various spring months being exceptionally interesting.
    • 2008, Nicholas Drayson, chapter 5, inA Guide to the Birds of East Africa, London:Penguin Books, published2012,→ISBN,pages24–25:
      [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 thedawn 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 thedawn chorus and parked at the station car park (£5.20 all day) in time for that 0456.

    • 1956 September 14, Harold E. Dinger, “The Dawn Chorus”, inWhistling Atmospherics (NRL Report;4825), Washington, D.C.:Naval Research Laboratory,→OCLC,page14:
      [T]hedawn 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 thedawn 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.
    • 1960 January 9, Joseph H. Pope, “Effect of Latitude on Diurnal Maximum of ‘Dawn Chorus’”, inNature: A Weekly Journal of Science, volume185, number4706, London:Macmillan and Co.; New York, N.Y.:St. Martin’s Press,→OCLC,page87, column 1:
      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[…]
    • 1964, D[avid] F[ranklin] Bleil, “Introductory Talk”, in D. F. Bleil, editor,Natural Electromagnetic Phenomena below 30 kc/s: Proceedings of a NATO Advanced Study Institute Held in Bad Homburg, Germany, July 22 – August 2, 1963, New York, N.Y.:Plenum Press,→OCLC,page 2:
      The frequency spectrum (Fig. 1) includes micropulsations (Pt, Pc, LPc, PP, SIP, IPDP), gyromagnetic resonances, Schumann resonance, solar whistlers […],dawn chorus, hiss, whistlers and sferics.
    • 1965,Robert A. Helliwell, “History”, inWhistlers and Related Ionospheric Phenomena, Mineola, N.Y.:Dover Publications, published2006,→ISBN,page21:
      Both authors used data from other stations to show that the time of maximumdawn 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 thedawn chorus by exciting proton plasma oscillations in the outer ionosphere. These oscillations would then reach the earth in the whistler mode.
    • 2006,Nicolas Collins, “Circuit Sniffing: Using Radios and Coils to Eavesdrop on Hidden Electromagnetic Music”, inHandmade Electronic Music: The Art of Hardware Hacking, New York, N.Y.; London:Routledge,→ISBN,page12:
      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, thedawn chorus, and the Aurora Borealis.
