On our last expedition three nests and sets of eggs together with 
the parent birds were collected. All were found in the neighborhood of 
Caicara. The first taken June 15th contained two fresh eggs. One 
is elongate ovate the other ovate in form. They measure 17.5 x 12 mm. 
and 16x12.2 mm. respectively. In color they are white with a slight 
creamy tinge, marked about the larger end with small dots and irregular 
blotches cf brown, varying from a light hazel to a dark chestnut. 
The nest looks exactly like a handful of broad-leaved drift grasses 
suspended from the tip of a slender drooping twig. The structure is 45 
cm. in length and 12 cm. in greatest diameter where the nest cavity 
is situated. There is no extension built out over the entrance to the 
nest cavity such as is seen in nearly all nests of T. cinereum, but only 
the round entrance partially concealed by loose blades of dead grasses 
hanging down over it. The grass blades forming the outer covering 
on the upper half of the nest all hang straight down over the sides, 
forming a perfect thatch. I imagine that the structure will shed water 
perfectlx'. The nest cavity is shallow, hollowed only a little below the 
entrance. There is a nest lining of fine soft grasses. This nest was 
suspended barely 75.72 cm. above the ground. It was in the centre of a 
thicket of undergrowth in the heavily forested belt of timber along the 
river bank. 
The parent birds were exceedingly shy, and not until after an hour's 
waiting was I able to make sure of the owner's identity and to collect 
the male parent. 
The second nest was found June 19th. It contained only one egg 
and that with incubation far advanced. This egg is ovate in form and 
measures, 17x12 mm. The ground color is similar to the two de- 
scribed above, but the markings consist of tiny dots and some larger 
spots of dark chestnut brown scattered over the entire surface of the 
egg, but most thickly about the larger end. The nest was in the centre 
of a thicket that bordered a pool of water in the thick forest. It was 
suspended from the extreme tip of a slender tAvig, that bent out over 
the water, and only about 91.5 cm. above its surface. 
The female parent was seen to fly from the nest, and was then col- 
lected. 
The third and last nest collected was taken June 29th. It contained 
two eggs in which incubation was far advanced. One egg is ovate ; the 
other is longer, nearly an elongate ovate. The two eggs measure 
17.25 -x 12.5 mm. and 18.5 x 12.5 mm. respectively. They are a little
