Juvenile Helpers

BNA: Almost all reports of Eastern Bluebird juveniles going into nesting cavities are when the adults ae feeding later broods. BNA says it's rare to have helpers. More likely with Western Bluebirds? EABLs: many items are alive and wriggling and not put far enough down the throat of nestlings. (Pinknowski 1975).
