he following is a list of the species of birds seen during four days' travel in the lower part of the Pima Indian Reservation. These four days were Septem- ber 8 and 9, 25 and 26. Forthe number of species noted, this list would be hard to surpass, embracing, as it does, 86 species seen on a tract of probably not more than five miles long by two miles wide. Migration was at its height, and, what might be more accountable for the presence of so much bird-life, very little shooting is done on the Reservation. A brief description of the ground may be of interest. The reservation is located on the Gila River, above its junction with the Salt River. A strip of land on both sides of the river is cultivated by the Indians, water for irrigation being drawn from the river and from a lake. The latter is of crater origin, and supplies an abundance of water. in consequence of this never- failing supply, a large area of ground covered with a dense willow growth is al- ways flooded, and at the time of my observations teemed with bird-life. The crops along the ditch tapping the lake were luxuriant. The corn, the beans and the pumkins sent forth such pleasant freshness that it is not to be wondered at that the tired, wing-sore birds after a night's flight, should be attracted by such a scene of peace and plenty. Away from irrigation was desert, dry and barren, support- ing only such plant life as can withstand long drougths, and the heat of a long suninlet. i.
