MONROE -- Neal Zimmerman paces on the lawn of Frank Wagner Elementary School. He occasionally looks to the sky, sometimes with binoculars.
He's been here since 5 and will wait nearly three hours for sunset.
He's come to count the Vaux's swifts, small and agile birds that flock to the school's chimney to roost. By day, the birds fly around the countryside, hunting for insects along the river. At night, thousands and thousands come for what is one of the great wonders of nature on the West Coast.
