I don't have experience with Horned Lark either; but, for whatever it's worth,
BirNET (https://birdnet.cornell.edu/api/) also says HOLA.

Yesterday, while watching the Sabine's Gull from the Hagg Lake Rec C area with
Paul Sullivan and others, we saw a passerine fly over that was making several
two-note calls (with a descending second note) that were unfamiliar to me. I
only saw the bird's profile, and it appeared to me to be somewhat larger and
plumper than a pipit, but didn't sound like a pipit or crossbill. I was able to
get Merlin started in time to capture two calls, which Merlin immediately
identified as a Horned Lark. Admittedly, Merlin has been a useful aid for
confirming suspected bird sounds, but it does sometimes make mistakes, and I do
not have a lot of experience with Horned Lark flight calls. A couple of kind
souls have weighed in that it is reasonable that it was a Horned Lark, but it
is not a slam dunk. I am posting a brief audio segment of the two calls and a
photo of the sonogram of the second call (right of red line at 5.4 sec) to see
if the collective wisdom of this group hears anything to help confirm or refute
the idea that this was a Horned Lark. Thanks, Rick Bennett, Sherwood
