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.

With luck
About 10% of wildlife watchers report a Sykes's Warbler sighting in Vijayawada on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 61st most-seen of the 93 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
April
In that month about 30% of wildlife watchers report a Sykes's Warbler in Vijayawada on a given day, against under 5% in January, March, May, July–August and October, the lowest months. That is one of Vijayawada's driest months, with about 20 mm of rain against 190 mm in October. September has too few records to rate.
Among the best
Of the 26 cities where we can rate Sykes's Warbler sightings, Vijayawada ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Vasai-Virar (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 Vijayawada (24 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.
