English: Coiled-string experiment (observer). Footage shows a bumblebee attempting to solve the coiled-string task after having observed a skilled demonstrator. The bee lands on top of the right and left tables several times and tries to access the reward. After 1 min and 40 s, the bee gets off the left table and starts exploring one of the edges for 5 s. The bee then climbs back onto the table, flies away, and attempts to obtain the reward from the top several more times. After 4 min, the bee lands on the right table, gets off it, and comes in contact with the string. She tries to power her way under the table where the string protrudes, walks around the table, and explores different edges of the two tables. She eventually climbs back on top of the left table and walks away. After 4 min and 30 s, the bee lands again on top of the right table, gets off it, and touches the string. She then tries to push her way under the table and doing so accidently moves the string with her legs. The flower doesn’t move closer and the bee keeps trying to push her way under the table and tries this on different edges. She finally climbs back onto the table, walks straight to the string side, and tries to reach under the table in an inverted position, extending the proboscis, ultimately failing to reach the reward.
