The lesser noddy (Anous tenuirostris), also known as the sooty noddy, is a seabird in the family Laridae. It is found near the coastlines of Comoros, Kenya, India, Maldives, Mauritius, Seychelles, Somalia, Sri Lanka and United Arab Emirates.
The lesser noddy was at one time considered as a subspecies of the black noddy (Anous minutus). The close relationship between the two species was confirmed by a molecular phylogenetic study published in 2016. The first formal description of the lesser noddy was by the Dutch zoologist Coenraad Jacob Temminck in 1823 under the binomial name Sterna tenuirostris. The genus Anous was introduced by the English naturalist James Francis Stephens in 1826. Anous is Ancient Greek for "stupid" or "foolish". The specific name tenuirostris is from the Latin tenuis for "slender" and -rostris "-billed".

Rare
Under 5% of wildlife watchers report a Lesser Noddy sighting in Mumbai on a given day, based on 279 verified sightings from GBIF citizen-science data. It is the 128th most-seen of the 283 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
September
In that month about 20% of wildlife watchers report a Lesser Noddy in Mumbai on a given day, against under 5% in October to June, the lowest months. That is one of Mumbai's wettest months, with about 380 mm of rain against almost none in January.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Lesser Noddy sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Mumbai, in our data
Mumbai is the only city on Wallace's Line with enough records to rate Lesser Noddy sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Laridae
The closest relatives of the Lesser Noddy that you can see in Mumbai (family Laridae, Gulls, Terns, and Skimmers) are Whiskered Tern (about 20%), Gull-billed Tern (about 10%) and Brown-headed Gull (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Lesser Noddy is recorded against all the birds logged in Mumbai (279 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.
