Sykes's warbler (Iduna rama) is an Old World warbler in the tree warbler family. It was formerly considered a subspecies of the booted warbler, but is now considered a full species. Its breeding range is from northeast Arabia to Turkestan, west China and Afghanistan. Like the booted warbler, many populations of the species migrate in winter to the Indian subcontinent as far south as Sri Lanka.
The English name commemorates the Colonel William Henry Sykes who served in the British military in India. Keyserling and Blasius gave no explanation of the genus name Iduna, though in Norse mythology Iðunn, or Iduna, is the goddess of spring and fertility who was changed into a sparrow to enable her rescue by Loki. The specific epithet rama refers to the Hindu god Rama, an incarnation of Vishnu.
Molecular phylogeny studies in 2009 suggested a clade sister to Chloropeta and separate from Hippolais in the strict sense resulting in the removal of this species from the genus Hippolais and placement in a resurrected older genus name of Iduna. There are differences in the nesting and egg morphology between rama and caligata.

Rare
Under 5% of wildlife watchers report a Sykes's Warbler sighting in Kolkata on a given day, based on 30 verified sightings from GBIF citizen-science data. It is the 199th most-seen of the 247 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 Sykes's Warbler in Kolkata on a given day, so our monthly data shows no clear season.
25th of 26
Of the 26 cities where we can rate Sykes's Warbler sightings, Kolkata ranks 25th at under 5%. The best odds are in Vasai-Virar (India, about 10%), Vijayawada (India, about 10%) and Jabalpur (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Sykes's Warbler is recorded against all the birds logged in Kolkata (30 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.
