BRITISH GUYANA BIRDS EGGS, 447 
some eggs have in addition black spots here and there. 
They hatch from February to July. — Two eggs (N°. 25). 
3. Tanagra palmarum Max. 
Cocoa-nut Sackie. 
The nest is like a cup and is built of small sticks and 
roots on the cocoa-nut- and other palms, and sometimes 
on shrubs. 
They lay three eggs. 
The egg — 27 mm. by 19 mm. — is pink white, spotted 
with dark red-brown and grey: there is a band of spots 
round the egg near its large diameter. 
They hatch in February, March and April. — One egg 
(N°. 26). 
4. Ostinops decumanus (Pall). 
Bunyah. 
They make a pendant nest about four, sometimes five, 
feet long, shaped like a club with a long handle, in co- 
lonies, from the extremities of the branches of palms or 
of tall forest-trees, of the stems of vines, coarse and 
fine grass, and of the fibres from the cocoa-nut-palm, 
and they line the bottom of the nest with leaves. The 
place of entrance is a small oval hole in the narrow part 
of the nest near its attachment to the branch. As the 
young get strong they make a second place of entrance 
near the bottom of the nest. The nest is completed in 
about fourteen days. They generally build on the lee side 
of the tree, and over water, not because they get any 
protection from the water, but because in the thick forest 
that is the only side of the tree they are able to build 
on. The young when hatched are naked and very helpless. 
They lay two eggs. 
The eggs vary much in length, being from 40 mm. to 
35 mm. by 25 mm.; they are rosy white, thickly marked 
with violet-red.
