Edinburgh Zoo says panda Tian Tian may be pregnant
LONDON (AP) - Edinburgh Zoo says there are signs that one of its giant pandas may be pregnant.
The zoo says nesting behaviour and changes in hormone levels suggest Tian Tian could be expecting a cub - or experiencing a phantom pregnancy, not uncommon in pandas.
The zoo said on Friday that the signs "give us cause for encouragement," although Tian Tian has not cooperated with an ultrasound that could yield more information.
If pregnant, she should give birth in late August or early September.
