croodle

To cower or cuddle together, as from fear or cold; to lie close and snug together, as pigs in straw.

Far ben thy dark green plantin's shade The cushat croodles am'rously

Oh! that I had wings-not as a dove , to fly home to its nest and croodle there

To fawn or coax.

To make a cooing sound.

Too dark to see well, but judge from movements of old bird's head and croodling noise.

Do pigeons croodle, or only doves?

A bird's coo, especially that of a dove.

[A]nd no sound falls on my ears, except the distant roar of a passing train, the song of linnets, and croodle of turtle-dove and cushat.

[A] third-storey apartment under the eaves loud with the croodles and canoodling of amorous pigeons.
