The little spiderhunter (Arachnothera longirostra) is a species of long-billed nectar-feeding bird in the family Nectariniidae found in the moist forests of South and Southeast Asia. Unlike typical sunbirds, males and females are very similar in plumage. They are usually seen in ones or twos and frequently make a tzeck call. They are most often found near flowering plants where they obtain nectar.
The distinctive long beak set it apart from other sunbirds. The sexes are similar, except that the female has a paler base on the lower mandible. Male has all black beak. They are found near their favourite nectar bearing trees, often species of wild Musaceae or flowers in gardens. They have a buzzy zick-zick call that is made regularly when disturbed or when foraging. Additionally, the song is series of rapid chipping notes and these can go on for long periods.
The genus name Arachnothera means "spider hunter" and the species epithet refers to the long beak. About thirteen geographic races are recognized. The nominate race longirostra (Latham, 1790) is found in southwestern India, central and northeastern India, foothills of the Himalayas and into Thailand... Wikipedia →

Rare
Under 5% of wildlife watchers report a Little Spiderhunter sighting in Cuc Phuong National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 111th most-seen of the 159 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.
January, March and November
In those months about 10% of wildlife watchers report a Little Spiderhunter in Cuc Phuong National Park on a given day, against under 5% in February, April–June, August–October and December, the lowest months. Those are among Cuc Phuong National Park's driest months, with about 75 mm of rain a month against 390 mm in August. July has too few records to rate.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Little Spiderhunter sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
21st of 25
Of the 25 parks where we can rate Little Spiderhunter sightings, Cuc Phuong National Park ranks 21st at under 5%. The best odds are in Danum Valley Conservation Area (Malaysia, about 60%), Khao Luang National Park (Thailand, about 50%) and Khao Sok National Park (Thailand, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Little Spiderhunter is recorded against all the birds logged in Cuc Phuong National Park (14 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.
