And whilst Noisy first turned receptive, she sought the corporate of a giant cheek-padded male named Nick. Nick and Noisy consorted, mating numerous instances, yet Biruté observed Mute a number of instances lurking within the history within sight, sneaking appears at his pal and her lover from in the back of the trunks of bushes. in contrast to Jane and Dian, who at the beginning defined what they observed in narrative box notes, Biruté recorded the behaviors she witnessed on a fee sheet, minute through minute.
