 The blue-throated hummingbird’s song differs from typical oscine songs in its wide frequency range, extending from 1.8 kHz to approximately 30 kHz.It also produces ultrasonic vocalizations which do not function in communication.As blue-throated hummingbirds often alternate singing with catching small flying insects, it is possible the ultrasonic clicks produced during singing disrupt insect flight patterns, making insects more vulnerable to predation.
