038287B4FFBBFFA5FF7EFAF6FE4C1032.taxon	description	We determined habitat type by the habitat type map in the general planning of the nature reserve. For nest trees, we photographed and collected specimens of leaves and branches. Nest materials were collected after fledging and identified, where possible. We determined egg colour by comparing with standard colorimetric cards (PANTONE formula guide, coated and uncoated) (Mo et al. 2023). Nest size, egg and nestling size were measured using vernier callipers accurate to 0.01 mm without damage. Nest height was measured using tape accurate to 0.01 m and nest tree diameter at breast height (DBH) was measured using diameter tape accurate to 0.01 cm. Egg, nestling and nest material mass were measured using an electronic scale accurate to 0.01 g. Egg mass was measured on the second day of the incubation period. Nestlings were taken from the nest-box nest using a small cardboard box, measured daily for mass and tarsus length and ringed at 15 days old. After the fledging of the nestlings, we weighed and classified the nesting materials in the nest box (artificial and other), identifying plant material to species where possible by consulting the Flora of China (eFloras 2008). We used an electronic scale for weighing and both direct and microscopic examination for classification.	en	Mo, Ruixin, Li, Yu, Kang, Zezhao, Duan, Yubao (2025): Breeding biology of globally endangered giant nuthatch (Sitta magna) in south-west China.

038287B4FFBAFFA5FF7EFC91FDEF1696.taxon	description	Spearman’s correlation was used to examine the correlation between nest temperature and egg-turning frequency. Egg-turning frequency is defined as the number of times egg-turning behaviour occurs within 1 h. Egg-turning behaviour refers to the act of a bird using its beak or feet to peck and move the eggs within the nest at intervals during incubation (Zheng 2012). One-way analysis of variance (ANOVA) was used to detect differences. Logistic regression was used to fit nestling growth curves. Data are presented as mean ± standard deviation (SD). Data analysis and graph production were performed using R Studio 4.1.1. In order not to destroy the natural nest, detailed information on egg size, egg mass, nestlings’ physical data, incubation behaviour and nestling brooding were obtained only from the nest-box nest.	en	Mo, Ruixin, Li, Yu, Kang, Zezhao, Duan, Yubao (2025): Breeding biology of globally endangered giant nuthatch (Sitta magna) in south-west China.
