BNA: Almost all reports of Eastern Bluebird juveniles going into nesting cavities are when the adults are feeding later broods. BNA says it is 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). See video and more info on Bluebird helpers at http://www.sialis.org/videofledgefeed.htm
Sappington (1977) reported that 2.26% of HOSP had nest-building helpers (in a 3 year study involving 221 nests), and 63.4% had feeding helpers.
