Loten's sunbird (Cinnyris lotenius), also known as the long-billed sunbird or maroon-breasted sunbird, is a sunbird endemic to peninsular India and Sri Lanka.

Like other sunbirds, it is also insectivorous and builds characteristic hanging nests.
Loten's sunbirds are small, only 12–13 cm long. The long bill separates this from the syntopic purple sunbird. The wings are browner and the maroon breast band is visible on the male under good lighting conditions. The males have pectoral tufts of yellow mixed with crimson that are used in displays. The adult male is mainly glossy purple with a grey-brown belly. The female has yellow-grey upperparts and yellowish underparts, but lacks the purple's faint supercilium. The call is distinctive buzzy zwick zwick and they are also very active often bobbing their head while foraging. They long down-curved bills and brush-tipped tubular tongues... Wikipedia →

Rare
Under 5% of wildlife watchers report a Long-billed Sunbird sighting in Sundarbans National Park on a given day, based on 42 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 112th most-seen of the 177 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April
In that month about 20% of wildlife watchers report a Long-billed Sunbird in Sundarbans National Park on a given day, against under 5% in August and October–March, the lowest months. That is one of Sundarbans National Park's driest months, with about 55 mm of rain against 480 mm in July. May and June have too few records to rate.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Long-billed Sunbird sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
11th of 12
Of the 12 parks where we can rate Long-billed Sunbird sightings, Sundarbans National Park ranks 11th at under 5%. The best odds are in Minneriya National Park (Sri Lanka, about 30%), Periyar National Park (India, about 20%) and Udawalawe National Park (Sri Lanka, about 20%).
GBIF citizen-science records
It is estimated from how often the Long-billed Sunbird is recorded against all the birds logged in Sundarbans National Park (42 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.
