However, the effect of this intervention may be temporary, and continued protection is needed to preserve the subspecies.
Wild great tits exhibit clear behaviors signalling 'divorce' long before the breeding season, according to a study by Oxford researchers. The team used data from the Wytham Woods great tit project and found that faithful birds visited feeding stations with their partners more often than those that went on to divorce.

In contrast to human bereavement, macaque mothers spent less time resting in the first two weeks after their infants' deaths.
An 11-year-old Asian small-clawed otter developed left-sided paralysis after a fall, but improved with treatment for a suspected fibrocartilaginous embolus. Follow-up MRI showed a diminished lesion one year later.
