Describe the general characteristics of upland game birds commonly hunted in Missouri.

Upland game birds are generally characterized by their habitat preferences, and those commonly hunted in Missouri are typically found in open fields and grasslands. These environments provide the necessary cover and food sources that upland birds thrive on. The open spaces allow hunters to spot and track these birds more easily, as they are often seen foraging on the ground or taking flight from low vegetation.

In contrast to the other options, upland game birds do not prefer deep forests or mountainous areas, which are more suited for other types of wildlife. While some birds may migrate, those commonly pursued in Missouri are generally resident species rather than highly migratory ones, making them more consistently available for hunting in the state's open field and grassland habitats. Additionally, they are primarily diurnal, meaning they are active during the day, which contrasts with the characteristics of nocturnal birds, making them easier to spot and hunt during daylight hours.
