Costa's Hummingbird song and calls

Birdsong and calls are often the easiest way to identify the Costa's Hummingbird, especially when the bird is hidden in dense foliage. Below is what to listen for.

Song

The male's song is a high-pitched, thin, and prolonged whistle, often described as a 'squeaky-toy' sound, 'tseee-tseee-tseee-tseee-tseee-tsew'. It is often given from a perch or during courtship dives.

Calls

Common calls include sharp 'chip' or 'tchip' notes, often given when agitated or during territorial disputes. A rapid series of 'tchip' notes may be heard during chases.

When they vocalize

Males sing most frequently during the breeding season to attract mates and defend territory. Calls are given year-round as needed.
