158 TRINIDAD AND TOBAGO BULLETIN. [XX.2,3&4. 



The nest, (PI. II, fig. 4) is attached, to the inner (under) side of 

 the end of a leaf or portion of a leaf of a large fern, or more rarely to a 

 leaf of Heliconia (Bahsier or Wild Banana). It is half cup shaped, 

 with a long thin tail like mass hanging beneath. 



The outside measurement of the nest is about 2\ inches across 

 and about 22 inches deep with, in addition, 5 to 6 inches of taiU 

 averaging a little over half an inch across and tapering to the tip. 

 The inside of the cup of the nest is about H mches across and 

 I i inches deep. 



The nest is loosely woven of dried brown surface roots chiefly 

 of fern, with a very thin coating of spiders web, but this is thicker 

 behind the leaf and at the point of attachment of nest to leaf and 

 also thicker on the tail. There is no distinct lining and the eggs 

 are visible through the loosely woven nest. 



The nest is usually about five to seven feet above the ground 

 (distinctly higher than the two last species) but occasionally lower 

 and is always within a few yards of a stream, frequently actually 

 overhanging the water. 



In 1920 nests were found as follows. 



(1) On March 21, one nest without eggs, on end of frond of 

 fern leaf. 



(2) On March 27, one partly constructed, one with young, and 

 one probably old nest, all on ferns close to or overhanging river, one 

 within two feet of the surface of the water. 



(3) On March 28, one nest on end of torn strip of leaf of 

 Heliconia about six feet from ground, containing two eggs. 



(4) On April 3, a nest on end of fern leaf in overhanging bank 

 of river, which had been under construction for about two weeks, 

 had one egg in it. 



(8) On April 8, one of the nests first seen on March 27, (believed 

 to be the one that then had young in it) had ' ne egg in it. On 

 April 9, two eggs, on April 18, still two eggs, on April 26, eggs had 

 hatched. This gives an incubation period of under seventeen days 

 and doubtful evidence of two successive broods in the same nest. 



(6) On April 28, a nest was under construction on the end of a 

 fern frond. On May 5, it had one egg, on May 6, still one egg, on 

 May 7, two eggs, on May 24, two eggs, on May 25, the eggs had 

 hatched. This gives an incubation period of 17-18 days. 



(7) On June 27, one nest with two eggs. 



(8) On July 10, one nest with one egg. 



In 1921 a careful search failed to produce a single nest up ta 

 February 15, so that it is probable that the breeding season had 

 not commenced by that date.
