Speaking of the Pine Grosbeaks of Siberia Mr. Seebohm says, “Almost all the forest districts are hilly and in the north, as the trees become smaller, they are also more thinly scattered over the ground and the interminable extent of wood is broken by occasional flat, open spaces and open marshes which become gray with flowers as soon as the snow melts. The scenery is much more park-like than further south and these birds are much more plentiful and more easily seen. In the large pine forests they prefer the banks of the rivers or the outskirts of some open place and may often escape detection because of their habit of frequenting the tops of trees. Within the Arctic circle many of the trees are small and on the hilly ground they are scattered in small clumps. In places like these the Pine Grosbeaks may often be seen perched conspicuously on the top of a spruce fir, twenty or thirty feet from the ground but looking so much like the last spike of the tree as frequently to escape notice.” The Pine Grosbeak is a retiring bird and would seem to be somewhat shy as it does not frequent the roadside or inhabited places except when forced to do so by the lack of food. This, however, is not the case, for in the forests where it makes its home it is not difficult to approach it. It will frequently alight and begin feeding within a few feet of an observer.

SCIENCES.] The song of the European form of this species is said to be “exceedingly agreeable, varied, melodious, sonorous—sometimes strong, sometimes soft.” It is also a mocker and to a limited extent will imitate the voices of other birds. Dr. Coues likens its song to that of the purple finch and says that during the late summer and winter it is “clear, sweet and flowing.” Its call note is single, sweet and plaintive not unlike that of the well known bullfinch. Pine seeds seem to form the principal food of the Pine Grosbeak though it also feeds extensively on those of the birch, alder and related trees. At times it will descend to the ground and gather the seeds of herbaceous plants and may eat a few insects. Dr. Dall writing of the Pine Grosbeak as he found it in Alaska, says: “I have opened the crops of a great many and always found them filled with what I for a long time supposed to be spruce buds, but on closer examination I found that they were the hearts of the poplar buds, with the scales and other external coverings carefully rejected. I have never found anything else in their crops.” In those regions where the mountain ash abounds the berries of this beautiful tree form a very important part of their diet whenever it frequents such a district.
