A species may display "herd" or "flock" behavior as a survival strategy for several reasons. These behaviors involve individuals of a species coming together in large groups and moving or acting collectively. This behavior is commonly observed in animals such as ungulates (e.g., deer) displaying herd behavior, or birds (e.g., geese) exhibiting flock behavior. Here's an explanation of how this behavior can serve as a survival strategy:

1. Protection against predators: Being part of a large group offers safety in numbers. Predators often find it challenging to target or single out an individual in a crowded group. By staying close together, animals can confuse, intimidate, or ward off predators more effectively. Additionally, many eyes and ears increase the chances of detecting threats or danger early, giving the group time to respond or escape.

2. Better foraging opportunities: In a larger group, there are more individuals searching for food. This increases the chances of finding suitable feeding grounds, as well as discovering and exploiting food sources more efficiently. Group members can also share information about food availability or guide each other to resources, enhancing their collective foraging success.

3. Efficient migration or movement: For species that migrate or travel long distances, moving in a herd or flock has advantages. Animals can conserve energy by taking turns leading the group, reducing wind resistance and allowing others to rest. This synchronized movement helps individuals navigate more efficiently, maintain a consistent pace, and minimize the risk of getting lost.

4. Social interaction and cooperation: Being part of a herd or flock allows for increased social interaction. It facilitates bonding, communication, and learning from each other. Social ties are valuable for survival as they promote coordinated behaviors, such as alarm calls, warning signals, or sharing parenting responsibilities. Cooperation within the group can enhance overall survival chances and improve the species' reproductive success.

To understand how a particular species displays herd or flock behavior as a survival strategy, researchers often conduct field observation, tracking the behavior of individuals within the group and collecting data on their interactions. They may also use techniques such as aerial surveys, GPS tracking, or statistical modeling to analyze the patterns and dynamics of herd or flock behavior.
