Temporal patterns of daily arrival and departure of sandhill cranes (Grus canadensis) at roost sites were examined along the Platte River in Nebraska during spring 1990. Departure times were earliest and arrival times were latest during the beginning of the 8taging season (9-21 March). Date within the staging season was the primary variable associated with time of initial departure and arrival, but arrival and departure times were also influenced by climatic factors. Departure times correlated positively with fog and precipitation (P < 0.05) and negatively with air temperature (P < 0.05), whereas arrival times correlated positively with both cloud cover and air temperature (P < 0.05).
