hummingbirds are known to be active proportionally to nectar production in flowers, decreasing throughout the day. Therefore, traplining hummingbirds can spend less time foraging, and obtain their energy intake from a few number of flowers. Spending less time searching for food means less energy spent flying and searching. Traplining bumblebees prioritize their routes based on travel distance and reward quantity. It is seen that the total distance of the trapline is related to the abundance of the reward (nectar) in the environment. Spatial cognition and memory Traplining can also be an indication of the levels of spatial cognition of species that use the technique. For example, traplining in bumblebees is an indication that bumblebees have spatial reference memory, or spatial memory, that is used to create specific routes in short term foraging. The ability to remember specific routes long-term cuts down foraging and flying time, consequently conserving energy. This theory has been tested, showing that bumblebees can remember the shortest route to the reward, even when the original path has been changed or obstructed. Additionally, bees cut down the amount of time spent revisiting sites with little or no nutritive reward. Bees with access to only short-term memory forage inefficiently. Advantages One of the main advantages of traplining is that the route can be taught to other members of the population quickly or over a period of hours, leading all members to a reliable food source. When the group works together on finding a particular source of food they can quickly establish where it is and get the route information transferred to all the individuals in the population. This ensures that the entire community is able to quickly find and consume the nutrients that are needed. Traplining helps foragers that are competing for resources that replenish in a decelerating way. For example, nectar in a plant is slowly replaced over time, while acorns only occur once a year. Traplining can help plant diversity and evolution by keeping pollen with different genetics flowing from plant to plant. It is mostly pollinators that use traplining as a way to ensure they always know where the food sources they are looking for are. This means that organisms like bumblebees and hummingbirds can transfer pollen anywhere from the starting point of the route to the final food source along the path. Since the path is always the same, it greatly reduces the risk of
