This bird is common in central Chile, in Patagonia, and although found in 

 Tierra del Fuego, it is not numerous there. Its specific name is very well chosen, 

 as I saw no bird in South America whose habits approach so near to those of our 

 tom-tits (Parus). It frequents bushes in dry places, actively hopping about them, 

 and sometimes repeating a shrill cry ; it often moves in small bodies of three and 

 four together. In August I found the nest of one in a valley in the Cordillera of 

 central Chile ; it was placed in a bush and was simply constructed.
