Abstract The cotton-top tamarin (Saguinus oedipus oedipus) has an extensive vocal repertoire which is derived from the variation of two basic elements and sequential combination those elements. A distinctive features analysis demonstrated at least 8 phonetic variants a short, frequency modulated call (chirp) five longer constant calls (whistles). do not describe points on single motivational continuum, but rather each variant represents different message. simple grammar presented to all...
Pygmy marmosets ( Cebuella pygmaea ) modified the structure of their trill vocalizations in response to pairing with a new mate. Prior pairing, individual displayed different acoustic parameters structure. Within first 6 wk after three four pairs produced trills that were more homogeneous between mates. Pairs had greatest difference prior convergence on greater number than having fewer differences prepairing The vocal following remained highly stable two could be recorded 3 yr initial...
Abstract The influence of various social environments on estrogen excretion, scent marking, and the expression sociosexual behavior was examined in cotton‐top tamarins ( Sanguinus o. oedipus ). Behavioral observations urine collections were conducted five females while first housed their natal family group or presence another cycling adult female then with an unrelated male a separate cage. only males groups female. Levels urinary estrone estradiol for measured by specific radioimmunoassays....
Sexual maturation and fertility were assessed in fourteen cotton-top tamarin (Saguinus oedipus) females under various social conditions. Six (20–28 mo of age) showed a suppression while living with their families. Hormonal profiles demonstrated low, acyclic levels urinary luteinizing hormone (LH) estrone-conjugates (E1C). A rapid onset ovarian pituitary cyclicity occurred when four the six removed from families paired an unrelated male. In one female, ovulatory LH peak as early eight days...
Abstract Pygmy marmosets ( Cebuella pygmaea ) use a variety of trill‐like vocalizations to maintain contact among group members throughout the day. Frequently, when one animal gives trill, other animals will respond antiphonally. Among three pygmy in captive group, there were clear patterns or sequences calling animals. All would call sequence more frequently than expected by chance, while likelihood an twice before each called once was less chance. One particular ordering individuals common...
