Less conimon than the preceding species, and like that species lives 
near the water especially in grassy marshes with scattering clumps of 
bushes and trees where it is as likely to be seen in the tree tops as 
among the bushes. It is active and flycatcher-like in habits. 
Adult birds have the eye seal brown ; bill black above, yellowish 
below with the tip blackish ; feet black. Young males resemble the 
female. 
A just completed nest of this species was found at Caicara on the 
19th of May. It was in the top of a small dead Moriclie palm-tree 
about 7.6 m. from the ground. Built of soft dry grasses, it was globular 
in form and about 18 cm. in diameter, with a small round entrance hole 
in the middle on one side. Unfortunately no eggs had been deposited 
when I cut the palm. Close beside the birds' nest was a nest of wasps. 
A second nest of Arundinicola leucocephala in process of construction 
was placed in the upright forks of a low shrub that grew near the edge 
of an extensive marsh. The nest was about 91.5 cm. from the ground, 
just above the top of the long marsh grass surrounding the bushes.

Native name Saiigrc de Toro. Common, frequenting the clumps 
of trees in open savanna regions. 
In the neighborhood of Caicara I found many nests of this species. 
They were usually in scrub oak from 1.52 m. to 3.5 m. from the ground, 
nearly always at forks well away from the body of the tree, and usually 
on one of the larger lower limbs. In no instance have I found them 
in any way concealed by surrounding leaves. The nests are neatly 
rounded, shallow cups set loosely in the forks of the supporting limbs. 
The materials used are rather short bits of dead grass, weed-stems 
and twigs, all presenting a brownish gray color in close harmony with 
the gravish bark of the supporting branches. There is an inside lining
