Fledging success is a poor indicator of the effects of bird blow flies on ovenbird survival
Sean M. Peterson, Henry M. Streby, Paul M. Kapfer
2009, Condor (111) 193-197
Infestations of bird blow flies (Protocalliphora spp. and Trypocalliphora braueri) have various negative effects on the condition of nestling birds. In the absence of other stressors such as inclement weather, however, infestation alone rarely reduces fledging success. Previous studies have documented effects of blow flies on nestling condition and fledging success. Without...
