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 blacK markings 

 become large rounded spots and the entire uuder 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. — W. F.~\
