Mothers of which species return to feed their infants only at dawn and dusk?

1. Cottontail rabbits

2. Snowshoe Hares

3. Opossums

4. Beavers

The correct answer is: Cottontail rabbits

Cottontail rabbits are known to exhibit a unique behavior when it comes to nursing their young. The mothers return to the nest primarily at dawn and dusk to nurse their offspring. This behavior is believed to be an evolutionary adaptation to reduce the likelihood of attracting predators. By being most active during these twilight hours, the mothers can help maintain the safety of their vulnerable young, as well as avoid potential dangers that might be present during the day when many predators are active. In contrast, the other species do not have this specific nursing behavior. Snowshoe hares typically do not exhibit a timed nursing pattern and may offer more frequent nursing opportunities throughout the day. Opossums do not have a particular schedule and often nurse their young whenever they are present. Beavers also do not strictly adhere to dawn and dusk for nursing; rather, their parental care includes bringing food to their kits during various times of the day. This distinctive behavior in cottontail rabbits is an excellent example of how animal behaviors can evolve as strategies for survival.
