   "abstract": "Studies of cliff-nesting raptors can be challenging because direct observations of nest\ncontents are difficult. Our goals were to develop a protocol for installing motionactivated\ntrail cameras at Golden Eagle (Aquila chrysaetos) nests to record diet\ninformation and productivity, and to estimate prey detection probability using different\ndiet study methods. In 2014 and 2015, we installed cameras at 12 Golden Eagle nests\nwith 18\u201442 d old nestlings. Following installation, we monitored adult behavior from\ndirect observation and post-installation image review. At two nests, adult eagles did\nnot return to nests or exhibited behaviors suggesting avoidance of the cameras, but\nreturned to the nests after cameras were removed. We visited the ten remaining nests\nevery 4 d to collect prey remains and pellets to generate prey-specific detection\nestimates for both images, and prey remains and pellets. Compared to inspection of\nprey remains and pellets, cameras recorded twice the number of prey (622 vs. 316),\nwere more likely to detect the smallest and largest prey, and cost half as much.\nCameras recorded productivity, fledging dates, and in one case, a nestling death. Trail\ncameras may be a reliable and cost-effective option to address clearly defined\nresearch goals and obtain required information about eagle behavior and nest\ncontents. However, cameras should be used judiciously because installation creates a\npersistent manipulation at the nest. Camera appearance should be minimized, and\npost-installation monitoring that allows for timely responses to nest avoidance behavior\nby adult eagles is important to prevent adverse effects on nesting success.",
