What is the average lifespan of a bird?
What is the average lifespan of a bird?
It is difficult to get an accurate figure on the lifespan of wild birds, says the American Bird Conservancy.
However, usually, the larger the bird species, the longer it lives. Therefore, the Ostrich in the Struthionidae family, lives longer than the House Sparrow in the Passeridae family.
For example, the large Wandering Albatross (Diomedea exulans) in the Diomedeidae family, with the longest wingspan of any bird on Earth – up to 350 centimetres (11.5 feet) across – can live up to 80 years.

RESEARCH: Sparrows are healthier when living in groups with diverse personalities
House Sparrows are healthier when living in groups with diverse personalities. Research scientists think that House Sparrows that live in groups in which different individuals have different personality types are healthier than those that live in groups with the same personality type.
The “surprising” findings suggest that personality diversity promotes not only a healthier society of sparrows, but also better physical and mental health for each individual within that society, says Zoltan Barta at the University of Debrecen in Hungary.
