Morphology
two-note + call
This is a straightforward compositional phrase: 'two-note' (two + note) describes the number/shape of the sound and 'call' is a sound or signal, so the overall meaning 'a call consisting of two notes' is directly derivable from the parts. The hyphenated numeral + noun + head noun pattern is transparent and cross-linguistically common, so a B1 learner who knows 'two', 'note', and 'call' will understand it.
Etymology
The term two-note call comes from the simple image of a bird making exactly two short notes in a row. That clear two-sound pattern helps people identify the bird, so the phrase means 'a birdcall that has two different notes'.
