Nesting
Patterns of 0.1 Manouria emys emys (Burmese Brown Tortoise )
By
Tracey Mitchell, Keeper
- Thursday
18th June 1992: 0.1 Went immediately from hit without pit to one
with when doors were opened at 8.30 am. Scraping took place.
Taken out at around 9.30 am and placed on compost mound while
hut was being cleaned. She wandered around the paddock for a while,
but eventually went back to the pit again. At locking up time;
4.30 pm, was still in pit. She was placed on compost mound in
the hope that she would lay there. Showed some interest by scraping
a little and putting her nose into the heap. Then began to wander
around the paddock again. Placed on heap several times and then
left until 10 pm when she was placed in hut without the pit. This
was to prevent her from laying in the pit and to encourage her
to go to the mound.
- Friday
19th June 1992: Some grass from mound put into pit. Tried to encourage
her to use the mound outside as much as possible, but she was
determined to use the pit.
- Monday,
22nd June 1992:
As
soon as she had completed laying her eggs she began using the more
moist peat and woodbark to cover up. She continued to do this until
late afternoon when she started to use some of the dryer grass.
By the morning of Tuesday 23rd June 1992, she had put a lot of the
grasses on top of her heap and had also dug down beside the nest
to cover it up.
Eggs
changed to a yellow colour the day after hey were laid, but gradually
became white again in colour.
