This parroquet is confined to the lower parts of the plateau region 

 (Pacific slope) and the higher parts of Guanacaste. It does not 

 descend to the lowlands of the coast region, as far as I have been able 

 to discover, but keeps above an altitude of about 1,000 feet at least. 

 Its habits are quite similar to the other species of the genus.

I rather expected to find P. hoffmanni gaudens Bangs in southern 

 Costa Rica, but found only a very slight trace of scarlet tips to the 

 feathers of the occiput, gaudens having all the feathers of the occipital 

 region strongly tipped with scarlet. One specimen from central Costa 

 Rica has the whole head with the feathers broadly tipped with golden- 

 yellow, the back more yellowish-green and the chest quite brownish. 



This species is only found among the higher mountains of the in- 

 terior, scarcely ever descending below 5,000 feet. They keep in the 

 heavy forest, always found at those heights, and are rather difficult to 

 find, except when feeding. I saw a flock of about a dozen birds at 

 Ujurras on one occasion and managed to secure three specimens.
