Now, for the last seven years, I've been working to document examples of animal grief -- in birds, in mammals, in domesticated animals and in wild animals -- and I believe in the reality of animal grief.
Zadnjih sedam godina radila sam na dokumentiranju primjera žalovanja u životinja; u ptica, sisavaca, u pripitomljenih i divljih životinja, i vjerujem da životinje žaluju.
