Pole takers: Dozens of blue herons perch on old lumber mill pilings in the Pend Oreille River at Usk, Wash., on Tuesday. Area birding enthusiasts said this is the time of year large groups of the birds can be seen migrating and resting in the Pack River Delta along Lake Pend Oreille. Soon they will disperse in smaller groups to nesting rookeries in cottonwoods or other woodlands near water.
