European Serin song and calls

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

Song

A distinctive, rapid, high-pitched, rattling, and tinkling trill, often described as sounding like 'a small bunch of keys being shaken'. It's a continuous, energetic, and somewhat metallic-sounding song, often delivered from a prominent perch or during a display flight.

Calls

Common calls include a short, sharp 'tsee-tsee-tsee' or 'tsit-tsit', and a softer 'tsooeet'. Alarm calls are sharper and more insistent.

When they vocalize

Most vocal during the breeding season (spring and early summer), with males singing frequently to attract mates and defend territory. Calls can be heard year-round, especially when in flocks.
