Dataset for Antigone canadensis (sandhill crane) foraging patterns influenced by crop, roost distance, and tillage intensity during spring and autumn migration at a primary stopover area Dataset for Antigone canadensis (sandhill crane) foraging patterns influenced by crop, roost distance, and tillage intensity during spring and autumn migration at a primary stopover area
We used data from 2.5 years of A. canadensis observations in the San Luis Valley to examine their foraging patterns during spring and autumn migration. We counted cranes weekly or bi-weekly each season and year during roadside surveys. We determined crop type (alfalfa, barley, pasture, potatoes, other grain, and other) during roadside surveys. We also recorded tillage intensity for grain...
