seems to be the more common form. Nests of this type may be placed in an up- 
right fork, or attached to a branch or twig on one side only, the other side being

supported by .some nearby leaf, stem or 
branch, or may be placed between two or 
more nearly parallel branches or close 
against one with the small lateral twigs 
embracing it as with encircling arms. 
The trill}' pensile is the “hangbirds” 
nest of the picture books, and has its 
support wholly at the top, depending from 
a small fork or from two near branches, 
with the opening rather small and the 
nest below expanding into the well-known 
form. This type is generally the most 
pleasing in effect and shows more elabor- 
ate and painstaking workmanship. It is 
usually placed near the end of some low- 
drooping branch well hidden among the 
leaves, and is .so strongly built that it 
may stand the wind and rains of .several 
.seasons before the final dissolution. 
The semi-pensile is a very different 
type, seldom arti.stic and generally Irail, 
rarely lasting over one sea.son. It would 
almost seem as if the main object sought 
for in its construction was the strength of 
the bottom. 'I'his, and perhaps an inch 
up on the sides is thick and strong, but 
above the walls are thin and transparent, 
and scarcely more than a frame work, but 
strongly woven and securely fastened to 
the supporting branches. This type is usu- 
ally placed near the end of an upward in- 
clining branch, which may be attached to 
it for its whole length; sometimes at the 
end of a drooping branch, but in any case 
it derives its support almost wholly from 
the side. The bottom never extends down 
to the base of any fork, a space of an 
inch or more always being left, but the 
nest is usually built as low down in the 
fork as its bulk will allow, thus gaining 
an additional ba.sal support; the top is 
generally .somewhat flaring being built 
out to convenient twigs. 
In the material used in construction the 
pensile nest shows the greatest variety nest or bullock oriole, no. 2. 
and the most careful selection. More string and long horse hairs are used, troth 
highly necessary, as the weight is sustained wholly from the top, and these woveti 
through the nest and over the supporting branches give a strength to the whole
