Adult cutthroat trout in the Salt River watershed were tracked from September-October 2005 until August 2006 using implanted radio transmitters. The fish were caught in the main river stem, spent October-March largely sedentery in pools, started to move more in April and then increased May-June for the spawning season, when 44% of the 43 fish remained in Salt River in April 2006, 37% moved to mountain streams, and 19% into spring streams, almost all preferring streams with manmade pools and gravel-cobble riffles. The fish didn’t use streams that dewatered in the summer or were blocked by manmade barriers.

In the Tanzanian Serengeti, several female ostriches contribute their clutch to the same nest, with each nest containing up to 38 eggs. Eggs were laid sooner in the western low-altitude area than in the eastern uplands.

Artificial ground-nesting birds‘ nests were placed along lines 200m to 34km from man-made vulture restaurants and scattered goat carcasses, and of the 67% lines predated by carrion-eaters, 90% of nests were attacked.
