It would grab a piece of down, brace itself and give a hard yank and out came the feather. By this time the hawks began to hop around on the boxes and liked to sit on top of the tent when the' sun was shining. They were very sociable and xvould come into the tent when allowed to do so, and showed much interest in the work being carried on, showing es- pecial interest in the bird bodies.

The smaller one died a few days later and from that time on I heard the older one utter the duck hawk yell only once.

GOLDMAN T HE Tulare Lake region occupies a depression 'along the western side of the southern part of the San Joaquin Valley in California. Besides Tulare Lake it may be understood to include the marshy areas from Summit Lake on the north to Kern Lake and Buena Vista Lake on the south. Summit Lake, perhaps less known than the others, is a small sheet of open water in the delta of Kings River, hemmed in by floating masses of peat and wooded islands. The sluggish currents of various sloughs carry the river waters away in two directions--north- xvard to the San Joaquin River and southward to Tulare Lake. In the course of field work for the Biological Survey the writer visited the re- gion in the early summer of 1907, remaining from June 18 to July 12. Small col~ lections of birds were made at Summit Lake, at various points along the northern
