(Anhimidae; Ϯ Northern Screamer C. chavaria) Gr. χαυνος khaunos spongy, porous; ref. the cellules or air-sacs beneath the skin of screamers; “When any part of the skin is touched by the hand a crackling is felt” (Latham 1785); “GENUS 99. CHAUNA (χαυνος fungosus, inflatus, inanis).  ...  Species: Parra Chavaria Lin. (Chaja Azara.)  Observat. Hanc avem (uti Glareolam, Cereopsin, Dicholophum) me nondum videsse, fateor; characteres genericos itaque, quantum licuit, e descriptionibus et iconibus hausi.   Chaunam, cujus nomen inde deductum est, quod cutis etiam pedum sub tactu crepet, scilicet cellulis inanibus ipsi substratis, a Palamedea et Parra distinguendam esse, mihi persuasum habeo.” (Illiger 1811); "Chauna Illiger, Prodromus, 1811, p. 253. Type, by monotypy, Parra chavaria Linné." (Peters, 1931, I, p. 142).

chavaria
Based on "Chavaria" of von Jacquin 1763, who tells us that it was the Spanish and indigenous name for this screamer at Cartagena, New Granada / Colombia (Björn Bergenholtz in litt.) (cf. Spanish name Chavarrí; French charivari  babble of noise, cacophonous music) (pace “Tupí (Brazilian) Indian name javariá for some sort of bird” (Jobling 1991)); "92. PARRA.  ...  Chavaria. 5. P. digitis elongatis, pedibus fulvis, occipite cristato.  Habitat in fluviis, lacubus & inundatis, vicinis flumini Cinu  ...  Aves rapaces ferre nequit & primo illas adoritur.  Vulturem Auram ibi frequentissimum, sæpeque obambulantem & approprinquantem, illico occurrit & expellit.  Indi, qui Gallinas, Anseres &c. nutriunt in magno numero, unicam Chavariam cicuratam habent, quæ cum reliqua Gallinarum turba per vicina pergit, numquam deserit, etsi volare possit & domum ad vesperam revertitur.  Ab homine adulto se tangi patitur & nemini nocet; contra Pueros se defendit sæpius.  Vox clara, alta, sed ingrata.  D. Jacquin." (Linnaeus 1766, Systema Naturæ, ed. 12, I, 260) (Chauna).
