(a) Nest elevation (grey bars, primary y axis) and length of entrance tunnel (white bars; secondary axis) of nests studied in the field in pre-monsoon, monsoon and post-monsoon periods. Each box represents the interquartile range, the line inside the box represents the median and the whiskers represent the range of the data. Mann-Whitney U test was used to compare nest parameters between different seasons. Bars carrying different letters or numbers are significantly different from each other. (b) Representative picture for nest entrances (arrow pointing towards the entrance) observed in pre-monsoon, monsoon and post-monsoon have been presented.
