Abstract	Urinary and fecal hormones were analyzed on average every other day in 17 female bonobos kept at four US zoos (San Diego Zoo and Wild Animal Park, Milwaukee, Columbus, and Cincinnati). Ovarian cycle activity was monitored throughout the 15-month study period using estrogen and progesterone profiles and swelling charts. Behavioral data on sexual activity were also collected on a daily basis. Fecal and urinary samples were analyzed using high pressure liquid chromatography (HPLC), gas chromatography-mass spectrometry (CG-MS), and nanoelectrospray. Preliminary results indicate that in urine, both conjugated progestin and estrogen metabolites were abundant, while in fecal samples, free progestin metabolites from the 5a-pregnane series were found. Although traces of estrogen metabolites were detected in fecal samples, long-term monitoring of ovarian activity in our study yielded no meaningful estrogen profiles. In contrast, fecal progestin profiles, after adjusting for a one-day delay in excretion, closely matched the corresponding urinary progestin profiles. Using the identical antibody and tracer for both, fecal and urinary progestins, fecal samples yielded approximately ten times the relative amount of progestins compared to urinary progestins. Thus, when converted using a regression formula, fecal progestins may complete the picture obtained from urinary progestins, particularly in cases where the urine sample record is unavailable or incomplete. Evidence of the usefulness of urinary cortisol as a measure of stress is presented.
