Question

The burrowing owl is found in dry, open areas such as grasslands, prairies, savannas, deserts, farmlands, golf courses, and urban areas throughout most of western United States and Florida, Central America, and most of South America. It makes its home in burrows of other animals and primarily eats insects and small rodents. As humans build more cities, nearby burrowing owl habitats change due to destruction of burrows and loss of prey. Which is the least likely outcome of the habitat changes that are described?
The niche of the burrowing owl may change as it adapts to the changes.
The niche of the burrowing owl may change as it moves to a new habitat.
The population of the burrowing owl may be reduced or even become extinct.
The population of the burrowing owl may increase in its new surroundings.

Answer 1

The least likely outcome is: "The population of the burrowing owl may increase in its new surroundings."

Reason: destruction of burrows and loss of prey reduces available habitat and food, lowering carrying capacity and causing population declines or local extinctions. By contrast, changes or movement can alter the owl’s niche (options 1 and 2) and declines/extinction (option 3) are plausible. While a few individuals might adapt to urban settings, an overall population increase is unlikely given the loss of nesting sites and prey.
