Method synopsis

Deployment of camouflaged security cameras or GoPro cameras near nests to record predation events, with careful timing to minimize nest abandonment and standardized recording parameters.

Synthesized from method descriptions across 2 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — The depredation of Mountain White-crowned Sparrow (<i>Zonotrichia leucophyrys oriantha</i>) nests by the golden-mantled ground squirrel (<i>Callospermophilus lateralis</i>) and long-tailed weasel (<i>Mustela frenata</i>) (2019), The Wilson J. of Ornithology. Implementations in other papers (listed below) may differ.

1. Camera deployment for video recording
   Cameras deployed when oldest nestling was 5-6 days old to reduce probability of nest abandonment or human-induced fledging, with researchers monitoring live activity before departing to ensure parents returned and camera presence did not induce abandonment
   Quantities: Cameras deployed at 5-6 day old nestling stageDuration: Monitoring from approximately 0700 h to 1400 h daily until recording completeConditions: Deployed only after confirming parental acceptance of camera presence
   Equipment: security cameras, GoPro Session camera
2. East River Valley video recording setup
   Camouflaged color CCD IR security camera mounted to 0.5 m tall wooden stake, placed approximately 15 cm from nest, connected via 15 m extension cord to external ES-TX9 battery and solid-state micro-DVR setup concealed in vegetation, recording at 352 × 256 frame size and 30 frames per second
   Quantities: Camera placed 15 cm from nest, 0.5 m stake height, 15 m extension cordDuration: Recording from 0700 h to 1400 hConditions: Camouflaged setup in vegetation
   Equipment: color CCD IR security camera, 0.5 m wooden stake, 15 m extension cord, external ES-TX9 battery, solid-state micro-DVR
