Fn:. 47.—Sbarp-shinni'd Family BUTEONID^: Hawks, Eagles, etc. Marsh Hawk; t'irciis ci/d.nevs hii(hnlus.—The mouse hawk, as it is known locally', is easily recognized by its wliite rump jDatch as it Ijeats low over meadows, marshes, and beaver ponds, hunting for small manunals. While restricted to the lower levels, it is reported from Sherburne Lake, Lake St. Mary, and the North Fork of the Flathead. Several were seen by us in the Belly "River country, at Waterton Lake, the Reynolds Lakes, and along, the Koote- nai Trail.

A few hours later, as we were crossing Swiftcurrent Pass, we saw a sharp-shin skim low over the ground and make a quick dive at a ledge of rock, when a ground squirrel with a sharp sqiieak dodged back out of his reach. After the hawk had dis- appeared, the half-grown ground squ
