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.

Blowfly and Animal Decomposition

Animal Decomposition is the process of an animal’s body degrading (breaking down) into organic matter after death.

There are two types of decomposition: abiotic and biotic.

Abiotic decomposition is degradation by chemicalal or physical processes.

Biotic decomposition is degradation by living organisms (insects, such as ants, beetles and flies, or by bacteria, or fungi).

The Blowfly (Chrysomya) is a prime decomposer of animal bodies.

Scavengers (hyena, vultures, wolves, foxes, rats etc.) also have a role in animal decomposition.

There are 5 stages to decomposition of small to large animals: (1) fresh, (2) bloat (accumulation of gases in the body), (3) active decay, (4) advanced decay, and (5) dry remains.
