40 BIRDS OF TIERllA DEL FUEGO 



Bay Settlement, in winter, about ten miles from timber. No 

 one can observe this bird without remarking that it has more of 

 the impudent assertion of the Blackbird than of the deprecating 

 manner of the Thrush. I was long in acquainting myself with 

 its many calls. Should one intrude on its domain, it shows 

 itself curiously hostile — mobbing one, following one persistently, 

 and uttering shrill whistles. If disturbed from covert, it utters 

 " Tut-tut ^'^ and flies out chuckling. On those still fine summer 

 evenings which are all too rare in these boisterous regions, 

 it sings from the tree-tops, far on into the night. The song 

 is sweet and Thrush-like, but somewhat limited in conception. 

 It gives one the idea of being practised rather than attained, 

 breaking off somehow at its most interesting point ; it neverthe- 

 less contains some beautiful full notes. Usually this Thrush 

 is seen in pairs. The young, when fully able to fly, have the 

 breast spotted similarly to that of the adult British Thrush. 



D'Orbigny says : — " Earement isolee, elle va plus ordinaire- 

 ment par couple, mais jamais par troupes, et fnit la societe 

 des autres oiseaux. Chose assez remarquable pour un oiseau 

 pen inquiete par I'homme, elle est des plus sauvage. Ses mceurs 

 sent celles de nos Grives ; son vol est court, saccade, peu 

 prolonge, jamais eleve ; vive dans ses mouvemens, elle marche 

 avec vitesse et fait souvent entendre une espece de siflSement de 

 rappel entre les differens individus." 



Darwin sums it up as "tame, silent, and inquisitive." 



Durnford's specimen was in company with Myiotheretes 

 rv.fiventris. 



The Ona name is ^^ KzoItsJ^
