This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
鸖 combines 霍 and 鳥. The exact historical development is uncertain, but it likely relates to a bird name or a phonetic compound.
The right side 鳥 suggests a bird, and the left side 霍 looks like rain over a bird-like shape. Picture a rare bird standing in the rain, its meaning unclear but tied to the bird family.
For カク, imagine a rare bird making a harsh 'caw-caw' sound: caw -> カク, and the bird calls out from the rain.
