Table 2 Arrival dates of satellite telemetry tagged Cormorants on breeding grounds as determined by the median between the last date detected in the northernly migration (before arriving on breeding grounds) and first date detected on breeding grounds. Data from Scherr et al. [74] of Cormorants migrating to breeding colonies in northern Lake Huron. Included is the overall mean arrival date for migrating Cormorants.
From: Predator telemetry informs temporal and spatial overlap with stocked salmonids in Lake Huron
