MAR. I9O3[ THE CONDOR 39 seems to be the more commou 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 N[?T OF BULLOCK O?IOL[, NO I. for in its ?nstruction was the strength of the bottom. This, and perhaps an inch up on the sides is thick and strong, but above the walls are thin and trausparent, and ?arcely more than a frame work, but strougly woven and ?curely fastened to the superting branches. This type is usu- ally plaid near the end of an upward in- clining branch, which may be at?ch? to it for its whole length; sometimes at the end of a drooping branch, but iu auy case it derives its sup?rt almost wholly from the side. The bottom neverextends dowu to the base ot any fork, a spa? of au inch or more always ?ing left, but the nest is usually built as low dowu in the fork as i? bulk will allow, thus gaining an additional ba?l support; the top is generally ?mewhat flaring being built out to couvenient twigs. In the material used in coustructiou the pensile uest shows the greatest variety 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 eucircling arms. The truly peusile 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 be[ore the final dissolution. The semi-pensile is a very different type, seldom artistic and generally frail, rarely lasting over one season. It would almost seem as if the main object sought I?EKT OF BULLOCK ORIOLE.

More string and long horse hairs are used, both highly necessary, ?s the weight is sustained wholly from the top, and these woven through the nest and over the supporting brauches give a strength to the whole
