ZOOLOGICAL SOCIETY BULLETIN 
important results by Dr. Chapman in “Bird 
Lore,” whose Christmas census lists I always 
peruse with as much detail and interest as if I 
had personally been a member of every party. 
Mr. Inness Hartley and I decided to have a 
Christmas census of the birds about our jungle 
laboratory at Kartabo, British Guiana, but this 
date occurs toward the end of the short rainy 
season. And Christmas was a very unusual day 
—as it rained from 5 A. M. to 5:30 P. M. The 
following day was almost as bad, so we had to 
compromise on the 27th of December, 1920. 
From dawn to dark we covered considerable 
ground. One trip in the launch was made a 
short distance down the Mazaruni River, a walk 
was taken along the beach, two trips through 
the clearing about the tents and bungalow, and 
four trips in the jungle, all within a quarter- 
mile circumference. All the observations were 
made by Inness Hartley or myself, and we were 
out for about half the day—at various times 
from 5:30 A. M. to dark at 6 P. M. 
On this 27th of December, 1920, the temper- 
ature was 72° at 6 A. M., 81° at noon, and 
76° at 6 P. M. The morning was quiet, while 
the trade wind blew gently from 1 to 6 P. M. 
The morning was cloudy up to 11:30 A. M., 
while four heavy showers fell between noon 
and 4 P. M., with bright sun between them. 
We observed 116 species of birds, distributed 
among 418 individuals. Of these a swift and 
a vulture may be classed as aerial; nine as 
water or shore birds; eighteen as inhabitants 
of the clearing, and the remaining eighty-seven 
tenants of the jungle itself. We had been 
studying the birds hereabouts for seven months, 
and yet it is so difficult to identify birds in the 
high trees with any certainty that we had to 
shoot about twenty species to be sure of them. 
Besides those which we identified, we each saw 
at least twenty or thirty more whose identity 
escaped both glass and gun. 
Several, such as the Goldbird and the Giant 
Goatsucker or Poor-me-one, were identified from 
the call alone—this being absolutely unmistak- 
able. 
It is interesting to note that thirty-seven spe- 
cies or 31% of the whole, were named by Lin- 
naeus, emphasizing the interest of this region 
as the origin of most of the collections which he 
named over one hundred and fifty years ago.
