Dear Dr. Huff: 
I wish to thank you for yours of December 8 
giving data on infections found in the blood smears 
that I collected last spring in Panama. This Is 1 
interesting but frankly I see no relation between the 
habits of the bird and the infection. 
In the two examples that carried Plasmodium, 
the first, Eucoroetis, is a tanager that Inliabiis ihe 
jungle areas In ®cfc growth and usually is found near 
the ground. The second, Tyrannus melancblicus, is 
a kingbird that is found on open perches at the edge of 
forest where It has clearer view all around. It is an 
aerial feeder in the main and lives in the open or in the 
more open outer branches of the trees. The two, thus, 
are quite dissimilar in habits.

S' 
Due to unforeseen Illness in my family, I will not 
be able to get away in January for a trip to the Upper 
Orinoco that I had planned. It looks now as though my 
next trip would be in May and June to Panama. I have 
your slides placed safely with my field gear so that they 
will be ready when I need them. 
Sincerely yours.
