What is the advantage and disadvantage of mark and recapture?

The mark and recapture method is advantageous for estimating wildlife populations because it allows researchers to gather data on species that are difficult to count directly, providing insights into population dynamics and ecology. However, a disadvantage is that it can be biased if the marked individuals experience changes in behavior, survival, or if the marking process itself affects them, leading to inaccurate population estimates. Additionally, if the population is not closed (due to Immigration, emigration, births, or deaths), the results may be misleading.
