Nope, it's not a Spanish "hello." It's banding code for HOrned LArk. A group of 5 visited me during my second day of confinement due to inclement weather. I was only able to grab this quick snap, through a window at maximum zoom, but I think you can see the Horned Lark behind the cardinal.
This is the second time in 11 years that I have seen Horned Larks in my backyard, and both times it was in the worst weather, with the top layer of snow frozen into a solid sheet of ice. If you want proof, see this photo below.
