Mean (±s.e.m.) surface-specific water vapour conductance (GH2O) for 62 British breeding bird species, sourced from a single museum donor, compared with the GH2O for the same species measured in eggs from multiple different donors. Analysis showed the values of GH2O to be highly repeatable for a species, and that egg donor origin was not a significant factor in the determination of average GH2O for a species. Values of GH2O for the three segments are combined (blunt end, equator and pointed end).
