During the month of July a study was made to determine the nesting sites or territories of species of birds which frequented that part of North Cascade Canyon immediately around the Lake Solitude area. The time available for the study was far too limited for any comprehensive coverage. Many species appeared to have completed their nesting early in the month when many areas were still covered with snow and thus records of their nesting sites were not found. For other common species fairly complete records were obtained. Project Number 109.
