The immature bird, obtained on November 9, has a small 
bill. The nasal plumes, which are much more developed in 
the young, appear to wear off in older specimens, leaving the 
nostrils somewhat exposed. Throat dull white, streaked with 
black, more pronounced in the old bird. The.under surface 
is dull greenish yellow, and the black markings are pear- 
shaped. As the bird advances in age these biacK markings 
become large rounded spots and the entire under surface,, 
including the throat, is rich golden yellow. 
The feet of the young bird are pale horn-coloured in the 
dried skin, in the adult they are dark lead-coloured. 
[This species is resident and the most common of our 
"Woodpeckers excepting Colaptes agricola ; it can be met 
with in the small second-growth woods close to Asuncion. 
Although it is common, I have never found its nest.— TV. F.]
