• <br />• <br />• <br />Figure 4: <br />Video evidence from 2004 suggested that <br />mammalian predation played an important role in the <br />status of the Peltier Island colony. In January, 2005, <br />metal flashing (36" wide) was wrapped around all <br />trees with nests or which could provide easy access <br />to the canopy by predators (Hjertaas 1982). <br />In response to 2004 video data, metal flashing was wrapped around the trunks of all <br />trees containing nests or any tree determined to provide easy access by mammalian predators <br />to the forest canopy near the active parts of the colony. The width of the flashing was 36" <br />and it was held to the tree with 2.5" screws (Figure 4). Flashing was either painted gray or <br />factory painted brown. Throughout the season, along with nesting activity, the status of the <br />flashing was monitored. <br />And finally, again in response to 2004 video data, local raccoons (Procyon lotor) <br />were live captured and fitted with radio collars (Figure 5). A total of six raccoons were <br />collared in the first week of March, 2005. Radio telemetry locations were taken 2 -5 times <br />per week throughout the heron nesting season and into the fall up until they denned up for the <br />winter. <br />5 <br />
