Malin 1959 Acer flammeus July 8 # along Leon Slough just straight out from end of Owl ridge. I also suspected a meeting pair a little W. of here. July 9 Found nest across river at 8 P.M. Contained 4 chicks, 1 egg. Nest #2 Tyrannus occidentalis about nest. 3 Ad 9, 1 Dm. 4, 3 Dm. 87. No pellets about nest site at all, + very few moult feathers. Watched male hunt for 45 minutes from in front of tent. During that time he caught 2 mice which he carried to what turned out to be the nest site, dropped down for only an instant & flew away again. Saw bird in one Territory defence of parts. I was sitting on small mound after catching first mouse, well N. of nest site. Sudden fly, flew straight + rapidly to ridge S. of nest where he began the willowy slow flight (mothy)- at same time I spotted a male owl hunting along ridge top. #A did one covey sleeping announcement then landed. After locating the nest went to ridge behind camp. Three male owls seen hunting. One along Owl ridge. One in Leon marsh at the S. end. + one 5 across Barbal Slough. Same old 3. The one hunting along Owl ridge did all his foraging along
