Are jaguarundis nocturnal? No, they are not exclusively nocturnal. Jaguarundis have been recorded moving around and hunting at all times of the day and night (sources: 1, 2 and 3).
However, it appears that this strange looking wild cat prefers to hunt by day (diurnal). The cat’s uniform coat indicates a ‘more diurnal lifestyle’ compared to the spotted cats (sources: 4, 5 and 6).
A study by MJ Konecny of radio-tagged jaguarundi in the wild found that they are mainly active in the daytime (source 7). The jaguarundis studied in the Cockscomb Basin, Belize, became active at dawn (04:00) and remained active until sunset at about 18:00. Their hunting activity peaked at around 11 am.
A study in Mexico confirmed that 85% of jaguarundi activity occurred during the daytime (source: 8).
