be up with the lark(s)(redirected from am up with the larks)
be up with the lark(s)
To be awake at a particularly early hour, especially at or before sunrise (i.e., the hour when larks sing). I don't know how he does it, but my husband is up with the lark every single morning. I won't have another pint, thanks. I have to be up with the larks tomorrow, so I'd better head home soon.
