Corrigendum to “Moult intensity constraints along the complete moult sequence of the House Sparrow (Passer domesticus)” [Avian Res. 14 (2023) 100125]

In the original version of this article, we published a figure showing a gap in the confidence intervals for body and tail due to data paucity for mid stages of moult progress. Here, we amended this problem adding data from the 2023 moulting season, during which we obtained 139 moult records from 98 individuals. The final sample size used for plotting these results are shown in the caption below. This amendment corroborates the conclusion already stated: body moult does not seem to be under physiological constraints, although primary moult appears to be tightly controlled to reduce aerodynamic losses.

Figure  8.  Moult speed in the House Sparrow, calculated as the average mass gain during the elapsed time between capture and recaptures. Local polynomial regression on moult progress calculated as the mean moult progress between consecutive captures (shaded ribbons depict 95% confidence intervals). Mass gain of primaries and rectrices have been calculated from one wing and tail side, respectively, and then multiplied by 2, i.e., assuming symmetry. Sample sizes for body and rectrices and primaries were n = 76 and 98 within-year recaptures from 56 to 40 individuals, respectively.
