The character looks like the variant of 鰂 in the first evidence, which the word means 烏賊/烏鰂 (squid). It is not related to the Cantonese word zak1 (e.g. 鰂魚涌 in HKSAR). If my understand is reasonable, the current radical is questionable.

In the second evidence, the head character should be the variant of 鷺. When I check the relative sentences of 鷺 in the ancient books, I found the following in 爾雅. So many books cited this sentence to explain 鷺. Maybe they are two characters there.
