Common, except during spring and summer. They are 
found both singly and in small parties. During a severe fog 
which we had in June last many were killed quite close to 
the city. I observed this Grebe near Montevideo in May, 
and at Baradero in April.

Resident and common in lagoons and ee arroyos." The 
female is not quite so brightly coloured as the male, and the 
elongated feathers on the head are shorter than in that sex. In

of primary importance to be accompanied by some specimen 
of the canine race.
