The specific epithet alpestris is Latin meaning "of the high mountains", from Alpes, the Alps. A molecular genetic study of the Alaudidae published in 2023 found that Temminck's lark (Eremophila...

Rare
Under 5% of wildlife watchers report a Horned Lark sighting in Philadelphia on a given day, based on 87 verified sightings from GBIF citizen-science data. It is the 184th most-seen of the 248 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Horned Lark in Philadelphia on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Horned Lark sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Horned Lark is recorded against all the birds logged in Philadelphia (87 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
