the nest for a period of 24 hours. At the shift in duty the incoming 

 bird entered the tunnel while its mate still occupied the nest. He 

 recorded the period when the young remained in nest after hatching 

 as "35 days or more." 



The nominate form of the ringed kingfisher, with type locality 

 in Mexico, ranges widely through Central America and in South 

 America from the northern coasts south, west of the Andes, to Peru 

 (Department of Lima), and on the east to central Argentina (La 

 Pampa, Buenos Aires) and southern Uruguay. In this vast area 

 there is no appreciable variation in color or size. 



The distinct subspecies C. t. stellata (Meyen), marked by shorter 

 bill, somewhat duller gray color above, with the secondaries promi- 

 nently barred with white, and in the adult male by slate-gray barring 

 on the under tail coverts, breeds in southern Chile, where it is found 

 from Concepcion (casually to Colchagua) to Tierra del Fuego, and 

 in Argentina from Rio Negro to Tierra del Fuego. As a winter 

 migrant it comes north to La Pampa and Buenos Aires.
