122 Mr. C. H. B. Grant on Birds collected in Argentina, 
one season; but I have no skins to prove this absolutely, 
and the reason for the February adult assuming ashy feathers 
needs further explanation. 
The young in first plumage are :— 
Ashy cinereous above, each feather edged with buffy 
white, as likewise are the wing-coverts, bastard wing, and 
inner secondaries; the tail is also tipped with buff ; below 
white or buffy white, striated with ashy on the breast 
and flanks ; under tail-coverts creamy with ashy centres ; 
axillaries and under wing-coverts edged with cream-colour, 
more ashy in some specimens.’'’ 
This is a common bird throughout the summer in the 
Ajo district, but was only once observed during the river 
expedition, when two males were seen near Pedernal on the 
30th of August. 
The males are striking and pretty objects and have all 
the habits of a Flycatcher ; but, unlike most of its congeners, 
this species has the habit of soaring for short distances with 
rapid beats of the wings from the top of some tree and 
returning to the same spot. 
In the evening it utters a mournful note of “ churinche,” 
and probably from this note comes the local name of 
“ Churinche.” 
The nest is composed of lichen lined with a few feathers 
and is a very flat structure with a slight cup-shaped depression: 
as a rule, it is placed in the fork of a tree clothed in lichen, 
often at no great height, and is extremely difficult to pick 
out.
