Sometimes it can be difficult to tell them apart. Below are some helpful tips to look for using their flight and pre-flight behavior. Following their takeoff runs and just as they become airborne, Trumpeter Swans usually pull their necks into a shallow "S" curve. This is seen only for a very brief time during their first wing beats. Tundra Swans hold their necks straight the entire time of the takeoff run and initial flight.

This characteristic applies to both land and water takeoffs. Trumpeter Swans may be the last birds in a mixed flock of Trumpeters and Tundras to take off.

With this motion they also have a variety of vocalizations. Head bobbing is a common form of communication between individuals and within the group. For example, Trumpeter Swans head bob during pair bonding behavior; before and after territorial disputes; as communication within the swan family group to show interest in take-off; as greetings to Trumpeter Swans in flight overhead; or when meeting other groups or family members; as part of alarm communication, and other types of communication.

Head bobbing and vocalization activity intensify when the birds are disturbed and reaches maximum intensity just prior to the birds taking flight note to photographers- look for the rapid increase in the rate and depth of head bobbing and vocalizations which occur just prior to take-off.

This behavior may be brief or absent if the birds are suddenly startled and take flight. Check out this video posted on our Facebook Page on October 13, to see pre-flight head bobbing.
