The markings of the third tiiil-featlier vary somewhat in specimens. Sometimes the whole tip is margined with brown ; some- times the white extends to the end; some- times both webs are margined with brown ; sometimes the outer is white entirely; sometimes the brownish wash on the back is more distinct. Some specimens (No. 52,7^2 and 52,701, males) from Sun River, Dakota, appear to be hybrids with orcgoniis. They have the general appeamnce of hyemalis, the back being nearly uniform with the head (with ' .Tuneo oresonus a wash of sepia-brown, however), and the head and neck of the same dark plumbeous ; the sides, however, are pinkish, and the plumbeous on the jugulum has its posterior outline convex, as in on-gomts. If, as there is every reason to believe, these specimens are really hybrids, then we have tlie two extreme forms of the genus connected by specimens of such a condi- tion ; thus, hyemalis with orcgomis, orcfjonus with canicqjs (==anncdc)is, Baird), and caniceps with cinercus (= dorsalis, Henry). It may perhaps be considered a serious question whether all (including alticola) are not, in reality, geographical races of one species. However, as there is no possi- bility of ever proving this, it may be best to consider them as representative species, and these specimens of intermediate characters as hybrids. Habits. The common familiar Snowbird of the Eastern States is found throughout all North America, east of the Black Hills, from Texas to tlie * Arctic regions. Wherever found, it is at certain seasons a very abundant and an equally familiar bird. It nests as far south, in mountainous regions, as Vi
