NESTING OF SOME GUIANA BirDs. 7 
have apparently been excavated by the birds themselves, 
or are old woodpeckers’ holes ealarged. Very frequently 
two different species of parrots occupy the same nesting 
tree and if the accounts of the Indians are to be relied on 
will even lay in the same nest. 
Mr. BARSHALL states that he has seen on several occa- 
sions what he takes to be a hybrid between the ‘‘Scree- 
cher” parrot, Chrysotis amazonica, and the “ Saurama,” 
Chrysotis fartnosa. Whether he is correét in his diag 
nosis of the species I am unable to say, but it appears to 
be certain that hybrid parrots are occasionally met with. 
While on this subjeét it is worthy of note that a very 
small form of the Screecher parrot is found on the 
Rupununi River. There is no difference in colour be- 
tween it and the common C. amazonica, but the Rupununi 
birds are so much less in size that at first sight they 
appear to be a different species. 
We know nothing concerning the habits of the little 
love-birds, Pszttacula sf., in their wild state, but in 
captivity they are very prolific, breeding all the year round 
and laying as many as four eggs at a time. 
Although a common bird on the Savannah the nest of 
Ara macao—the finest of our Macaws—has never been 
seen by the Indians, who all agree in declaring its nesting 
place to be unknown. 
On the other hand the blue and yellow Macaw, 4. 
ararauana, breeds regularly in the trunks of old Eta 
palms and Ara chloroptera, the red and blue Macaws, on 
the tops of the tallest trees. 
This last bird, Mr. BARSHALL informs me, often makes 
its nest ata very moderate height from the ground, so that 
it can easily be reached by climbing, but in the Savan-
