Ecological factors regulating brood attendance patterns of the Western Sandpiper Calidris mauri
Parental brood attendance patterns vary greatly among shorebird species. For monogamous calidridine species, biparental care with female‐first brood departure is most common. It is believed that adult sandpipers balance potential individual survival costs associated with extended parental care again...
