The lesser frigatebird (Fregata ariel) is a seabird of the frigatebird family Fregatidae. Around 75 cm (30 in) in length, it is the smallest species of frigatebird. It occurs over tropical and subtropical waters across the Indian and Pacific Oceans, as well as off the Atlantic coast of Brazil.

The male has a striking red gular sac, which he inflates to attract a mate. The female is slightly larger than the male and has a white breast and belly. Frigatebirds feed on fish taken in flight from the ocean's surface (often flying fish), and sometimes indulge in kleptoparasitism, harassing other birds to force them to regurgitate their food.
The lesser frigatebird was first described as Atagen ariel by English zoologist George Gray in 1845 from a specimen collected on Raine Island, Queensland, Australia. The lesser frigatebird is one of five closely related species of the genus Fregata. The other four are the great frigatebird (F. minor), Christmas frigatebird (F. andrewsi), magnificent frigatebird (F. magnificens), and Ascension frigatebird (F. aquila... Wikipedia →

Likely
About 40% of wildlife watchers report a Lesser Frigatebird sighting in Komodo National Park on a given day, based on 128 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 22nd most-seen of the 76 birds we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
January and August–September
In those months about 50% of wildlife watchers report a Lesser Frigatebird in Komodo National Park on a given day, against about 20% in March to May, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Lesser Frigatebird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 4
Of the 4 parks where we can rate Lesser Frigatebird sightings, Komodo National Park ranks 2nd at about 40%. The best odds are in Raja Ampat (Indonesia, about 60%).
GBIF citizen-science records
It is estimated from how often the Lesser Frigatebird is recorded against all the birds logged in Komodo National Park (128 verified sightings from 2019 to 2026), 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.
