What time of day is best to see a Merlin?

Between 8 and 11 am

Across all the parks we cover, that three-hour window holds the most Merlin sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

Of the 55 cities where we can rate Merlin sightings, Guadalajara ranks 29th at under 5%. The best odds are in Calgary (Canada, about 20%), Montreal (Canada, about 10%) and Edmonton (Canada, about 10%).

Where does the Merlin sighting chance come from?

GBIF citizen-science records

It is estimated from how often the Merlin is recorded against all the birds logged in Guadalajara (14 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.
