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 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 →

Rare
Under 5% of wildlife watchers report a Lesser Frigatebird sighting in Kochi on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 225th most-seen of the 235 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 Lesser Frigatebird in Kochi on a given day, so our monthly data shows no clear season.
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.
Among the best
Of the 5 cities where we can rate Lesser Frigatebird sightings, Kochi ranks 5th at under 5%, level with the leaders once rounded. The best odds are in Denpasar (Indonesia, under 5%), Mumbai (India, under 5%) and Shanghai (China, under 5%).

The closest relatives of the Lesser Frigatebird that you can see in Kochi (order Suliformes, Gannets, Cormorants, and Allies) are Little Cormorant (about 60%), Oriental Darter (about 30%) and Indian Cormorant (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Lesser Frigatebird is recorded against all the birds logged in Kochi (6 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.
