The original version of this article, unfortunately contained errors.

In the Abstract section originally reading, “(1) the male in between social and spatial relationships indicated that they are independent from each other.The present study is the first to reveal the characteristics of spatial positioning in a mammalian group using drone technology.” should be read as “(1) the male in”. Under the section “Distribution of distance between individuals” the correct data should have been “... K-S test, n = 1708 ...” instead of “...-S test, n = 1708...” and under the section “Social network analysis”, the sentence “We found a significant correlation between the grooming and inter-individual distance networks (QAP test, r = 0.51, p < 0.01) but not between the grooming and proximity networks (QAP test, r = − 0.14, p = 0.27).” should be read as “We found a significant correlation between the grooming and proximity distance networks (QAP test, r = 0.51, p < 0.01) but not between the grooming and inter-individual networks (QAP test, r = − 0.14, p = 0.27).
