Spatial and isotopic niche from observations and reanalyses. Our consistency therein across years; also see Wakefield et al.
For future studies on fledging of chicks and molt approximately 3—7 weeks individual specialization, multiple sampling events across during which body reserves for molt are accumulated; different time periods within and among years would Warham ; Strangeadult females may not dis- therefore be desirable.

This also coincides with our result of significant repeatability of red blood in either d15N or d13C between red blood cells and feath- cell d15N and d13C across years.
