The booted warbler (Iduna caligata) is a species of passerine bird belonging to the family Acrocephalidae, the reed and tree warblers. This species breeds in Eastern Europe and western Asia, wintering in south Asia. it is a regular vagrant to Western Europe.
The booted warbler was first formally described as Sylvia caligata by the German physician, explorer, botanist and zoologist Martin Hinrich Carl Lichtenstein with its type locality given as the Ilek River, near Orenburg. This species is now classified in the genus Iduna, the tree warblers, within the family Acrocephalidae. All the "Old World warblers" were formerly classified within the wastebin taxon known as Sylviidae sensu lato, but in the late 20th Century, molecular studies resulted in this taxon being divided into a number of families.
It was formerly considered to be conspecific with Sykes's warbler, but the two are now usually both afforded species status. The booted warbler belongs to the genus Iduna which was proposed by Alexander Keyserling and Johann Heinrich Blasius in 1840, but they gave no explanation of the genus name, though in Norse mythology, Iðunn, or Iduna, is the goddess of spring...

Rare
Under 5% of wildlife watchers report a Booted Warbler sighting in Bhopal on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 137th most-seen of the 197 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.
October and December
In those months about 10% of wildlife watchers report a Booted Warbler in Bhopal on a given day, against under 5% in January–September and November, the lowest months. Those are among Bhopal's driest months, with about 15 mm of rain a month against 440 mm in July.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Booted Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
21st of 39
Of the 39 cities where we can rate Booted Warbler sightings, Bhopal ranks 21st at under 5%. The best odds are in Coimbatore (India, about 20%), Vasai-Virar (India, about 20%) and Novosibirsk (Russia, about 20%).
GBIF citizen-science records
It is estimated from how often the Booted Warbler is recorded against all the birds logged in Bhopal (22 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.
