he National Park Service is collecting blood and feathers from young eagles along the Mississippi River on Tuesday to measure contaminants they ingest and fitting them with leg bands so the birds can be identified if they are ever captured again. Jim Campbell-Spickler, a "forest canopy biologist," climbed a tree and collected a 4-week old eagle for the sample. Because the eagle was too young to draw blood, the eagle was measured and weighed and returned safely to its nest. ] SHARI GROSS/STAR TRIBUNE (The Minnesota Star Tribune)
