296 Brey, Migration at Raleigh, N. C. ae 
It might be interesting to note that we observed but few locusts 
in the field, perhaps proving that the Chufias made special effort 
to secure them. I imagine that the examination of a large series 
of gizzard contents would reveal a great variety of food stuff. 
The tame birds greedily ate the bodies of birds and rats, while 
one individual consumed small tacks and broken china without 
embarrassment. Of special interest perhaps was the finding of 
the double ovary in two of the specimens, while another female 
had but the usual single ovary. 
It is difficult to estimate just how numerous these birds are. 
There is one section of the “Gran Chaco” of northeastern Argentina 
that is called “Campo de las Chufias” where the natives go each 
year to secure the eggs of this bird for eating purposes. We believe 
these to be the same species as Chunga burmeisteri; the red-legged 
variety is said to live in the uplands and on the mountain slopes. 
The flesh of this bird is very much esteemed by the natives, who, 
after carefully boiling the meat, make it into a stew and serve with 
potatoes, rice, raisins and a quantity of spice which forms quite a 
palatable dish and, after the usual diet of very young goat or kid, 
is a most welcome change. 
THIRTY-TWO YEARS OF BIRD MIGRATION AT 
RALEIGH, NORTH CAROLINA. 
BY C. S. BRIMLEY. 
In the spring of 1885, I first began to fill out migration schedules 
for the U. S. Biological Survey, and have kept up the habit every 
succeeding spring since, except in 1902, in which year I made 
observations, but lost my records, and the little data I have for 
that spring comes from the dates of a few skins which I collected 
then. The share others have had in the work is indicated at the 
end of Table I. 
Not only have “arrivals” in spring been noted, but the “lasts”
