Nov., 1918 NESTING O1?' THE ROCKV MOUNTAIN JAY 203 a disappointment just the same, these eggs were so nearly ready to hatch that it was very difficult to save them. Since the last occurrence I have received three sets of Rocky Mountain Jay's eggs, taken in Colorado, each set accompanied by the nest and parent bird, and with detailed reports by the parties taking them. I will designate these as numbers 1, 2 and 3 in the order received by me, and quote from the re- po?s accompanying them. Set no. 1. "From Grande County, collected May 2. Altitude 8,600 feet; nest in a lodge-pole pine about thirty feet high and three and one-half inches Fig. 40. NEST AND EGGS OF THE ROCKY MOU,NTA1N JAY; SET NO. 1. in diameter at breast height; nest about twenty-five feet from the ground, in a rather bushy top, located close to the trunk on a small limb. Some of the strings used in the nest were neatly bound around the limb upon which it rested. "The mother bird showed no unusual actions that I could observe, but while the nest was being secured, hovered about the nearby trees, flying back to the nest tree once or twice, and all the while making a terrible fuss." The two eggs in this nest were more than three-quarters advanced in incu- bation.
