Results


In conclusion to my study of the behaviour of our Fossas during the period of oestrus, it is apparent that the most frequently observed behaviour is sleeping from both animals (31.8%), suggesting that they have been more active at night during the time of this study.

Both Fossas had full access to all areas of enclosure at all times (except the male when cleaning).
Charts have been included to breakdown the results discussed here, and the numbers in brackets included in the conclusion indicate which no. chart to refer to.
When individuals are referred to, their names are printed in inverted commas.

Male Observations

The male Fossa spent more time asleep during 7.30 and 11.00 am (1), but spent more time pacing between 11.30 am and 1.30 pm (2). Scanning the enclosure whilst stationary was the third overall most observed behaviour ‘Forsell’ did this more between 11.30 am and 1.30 pm (2).

A high percentage of time was spent resting by both animals (13.9%).
The male spent slightly more time resting than the female.
Vocalising was observed by ‘Forsell‘, mostly whilst scanning the enclosure looking for her, highest levels of vocalising were recorded between 7.30 am and 11.00 am (1).
Erections were not seen frequently but those observed were between 11.30 am and 1.30 pm (2).
Scent marking was also frequent between 11.30 am and 1.30 pm (2).
Climbing was seen by ‘Forsell‘, mainly between 2.30 pm and 5.30 pm (3).
Grooming was not seen regularly by the male, but more so between 7.30 am and 11.00 am (1).
Feeding was mainly observed by the male mostly throughout the afternoon between 2.30 and 5.30 pm (3).

For 5.8% of the time neither animal was seen from where I was conducting the study. (I didn’t want to be seen by them as this would affect their behaviour).

‘Forsell’ was not visible to me mostly between 2.00 pm and 5.30 pm.
