Short answer

The decomposition time of a crow can vary depending on various factors such as temperature, moisture, and presence of scavengers. On average, it takes around 3 to 6 months for a crow to completely decompose.


The decomposition of a crow follows a natural process known as decay. This process can be divided into several stages, each characterized by specific changes in the crow's body. Initially, after the crow's death, the skin becomes discolored and gradually loses its elasticity. As microorganisms break down the crow's tissues, a putrid odor begins to emanate from the carcass. This phase, known as the fresh stage, usually lasts for a few days.

As decomposition progresses, the crow enters the bloated stage. Gases produced by bacteria accumulate inside the body, resulting in significant swelling and distortion. This bloating may cause the crow's feathers to separate, exposing the decomposing flesh. The crow's abdomen becomes distended and its internal organs start to liquefy. This stage typically lasts for about a week, after which the crow begins to collapse due to the release of the built-up gases.

In the final stage, known as the advanced decay stage, the crow's flesh substantially decomposes. The remaining tissues break down even further, and the carcass takes on a wet appearance. Bones become more visible as the crow continues to deteriorate. At this stage, insects and scavengers play a significant role in consuming the remaining flesh, leaving only bones and feathers behind. Eventually, the crow is reduced to mere skeletal remains, completing the natural process of decomposition.

Intresting facts

  • The decomposition of a crow, like any organic matter, follows a specific process known as decomposition, which involves the breakdown of organic compounds by bacteria and other decomposers.
  • The rate of decomposition of a crow can vary depending on various factors such as temperature, humidity, access to oxygen, and the presence of scavengers.
  • Initially, flies and other insects are attracted to the decaying crow and lay eggs on its body, which hatch into larvae (commonly known as maggots) within hours. These maggots feed on the rotting flesh.
  • As the decomposition progresses, bacteria and fungi play a crucial role in breaking down the remaining tissues. Bacteria release enzymes that break down proteins and fats while fungi help break down the remaining organic matter, including feathers and bones.
  • Eventually, all that remains from the decomposition process is a skeleton or scattered bones, as the soft tissues are fully decomposed, and nutrients are returned to the surrounding environment.

Summary and final thoughts

The decomposition time of a crow can vary depending on various factors such as environmental conditions, scavengers, and access to oxygen. Generally, the decomposition process starts quickly with the breakdown of soft tissues by bacteria and insects, progressing to bones and larger body parts. The duration can range from a few weeks to a couple of months. However, it is important to note that decomposition rates are not precisely predictable due to the complexity and variability of decomposition processes. Factors like temperature, humidity, and presence of scavengers can significantly impact the rate of decay. The complete decomposition of a crow typically involves the return of its organic matter to the environment in the form of gases, liquids, and minerals, ultimately contributing to the cycle of life and natural recycling.
