The annotated ideograph in the evidence looks like it includes 烏 as a component, whereas the ideograph below it definitely includes 鳥 as a component.

Please provide the whole page of this evidence, as it difficult to understand the meaning of the character from this small extract.

The character here shares the same context with ⿸厂⿸虍鳥. The text is from 韡华阁集古录跋尾丙篇, but I don't have a scanned copy in hand.

「雁字作⿸厂⿸虍鳥从厂⿸虍鳥，⿸虍鳥，疑鳥之古文奇字也。」
