Every morning the birds in the woods sing at the top of their voices.
Tips
usage
引 here means 'to stretch / draw out' and 吭 means 'throat', so the literal image is stretching the throat to sing at full volume. Note 吭 takes this less common reading; the everyday word 吭声 ('to utter a sound') uses kēng instead.
