An increase in which of the following could increase the long-billed Curlew population?
A. Forest habitats
B. Pesticide use
C. Milkweed
D. Grassland habits
D. Grassland habitats
Grassland habitats are the preferred nesting sites for long-billed Curlews, so an increase in grassland habitats would likely lead to an increase in their population. On the other hand, forest habitats and pesticide use could negatively impact the population of long-billed Curlews. Milkweed is not known to have a direct impact on the long-billed Curlew population.
