The survivorship data for the Northern Spotted Owl can be used to calculate the age-specific probability of death. If an owl survives its first year, its probability of dying in any subsequent year decreases to 0.13 and remains nearly constant for the rest of its life. Given this, which type of survivorship curve best describes the Northern Spotted Owl?

The correct answer is - Type II survivorship curve.

Explanation:

Type two survivorship curve is the curve that presents in such organisms who shows a relatively constant rate of survivorship or mortality rate throughout their life span. This is a very common survivorship curve in lizards, birds, rodents.

In this example, the northern spotted owl shows a mortality rate of 0.13 and remains constant throughout his life span which can be best described by the type II survivorship curve.

Thus, the correct answer is - Type II survivorship curve.
