two of the small islands near Luzon. Mearns has described 
Gerygone rhizophorx from Mindanao, but there seems to be no 
record of the genus from Samar, Negros, and the other islands. 
My experience with Gerygone simplex indicates that it prefers 
mangroves and open, second-growth bamboo. 
Mr. E. H. Taylor recently found this flycatcher nesting in the 
vicinity of Alabang, Laguna Province, Luzon. The nests were 
in second-growth shrubs and bushes. 
One nest was about 2 meters from the ground in a spiny shrub, 
Capparis horrida Linnaeus (Plate 1). It is composed of plant 
fibers and covered with cobwebs. It is suspended near the end 
of a small twig, and its general appearance suggests the nest of 
some sunbird or bushtit. This nest is about 30 centimeters long 
and 5 centimeters broad. At the middle of one side there is a 
circular opening about 2.5 centimeters in diameter which is 
nearly concealed by an overhanging roof. This roof projects 
about 4 centimeters from the side of the nest. The two eggs 
were slightly incubated and measure 15.8 by 12 and 16.6 by 12.2 
millimeters, respectively. The ground color is very pale pinkish 
buff. Near the larger end of the egg is a definite ring formed 
of spots of mahogany red to Hay’s russet. There are a few spots 
scattered over the rest of the egg. 
Another nest collected on the same date, June 4, 1920, was 
about 3.5 meters from the ground in a large-leafed shrub, Seme- 
carpus cuneiformis Blanco (Plate 2) . This nest is only 20 centi- 
meters long, and the roof over the entrance does not hide the 
opening so well as in the other nest. The two eggs of this set 
contained such large embryos that they could not be blown. 
These eggs are slenderer than those of the other set; the mark- 
ings are more scattered and scarcely form a zone. The measure- 
ments in millimeters are 18.5 by 12.2 and 18.1 by 12. 
Several species of the genus Gerygone are resident in Austra- 
lia, and the nests and habits are described by North. 1 The 
picture of the nest of Gerygone fusca (Gould), on page 197 of 
North’s work, resembles somewhat the longer nest of Gerygone 
simplex, but the Australian species elaborates the roof into “a 
narrow bottle-neck like entrance.” Another nest of Gerygone 
fusca, figured by North, 2 resembles closely the long nest of G. 
simplex. The various Australian gerygones lay two or three 
eggs in a set.
