The methods section of the main text should state that the results reported are those of maturation experiments that were carried out for 1 h (not 24 h); feather morphology did not survive for 24 h under the conditions explored. This does not alter the primary conclusions of the paper that melanosomes can survive some thermal maturation although their dimensions may be altered, whereas keratin is likely to degrade.
