Cheep

I cannot cheep like a sparrow. I'm a pigeon.

[…] a brood of ducklings, which had lost their mother, filed into the barn, cheeping feebly and wandering from side to side […]

O Swallow, Swallow, if I could follow, and light / Upon her lattice, I would pipe and trill, / And cheep and twitter twenty million loves.
