The proposed study will look at the effects of introduced trout on alpine birds, effects that may result from competition between trout and birds for shared invertebrate prey. The study will take place in Humphreys Basin, Sierra National Forest, California. The proposed research will describe (1) the spatial distribution of foraging and nesting by Gray-crowned Rosy Finches (Leucosticte tephrocotis) and American Pipits (Anthus rubescens) relative to locations of fishless versus fish-containing lakes; (2) the temporal sequence of daily and seasonal foraging patterns of these bird species relative to the availability of aquatic insect prey; and (3) the consequences of foraging location to incubation times, egg survivorship, nestling feeding rates and amounts, and fledgling size and survival rate.
