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 Kozhikode on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 169th most-seen of the 229 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
October
In that month about 10% of wildlife watchers report a Booted Warbler in Kozhikode on a given day, against under 5% in November to September, the lowest months. That is one of Kozhikode's wettest months, with about 250 mm of rain against 5 mm in January.
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.
28th of 39
Of the 39 cities where we can rate Booted Warbler sightings, Kozhikode ranks 28th at under 5%. The best odds are in Coimbatore (India, about 20%), Vasai-Virar (India, about 20%) and Novosibirsk (Russia, about 20%).
Same family: Acrocephalidae
The closest relatives of the Booted Warbler that you can see in Kozhikode (family Acrocephalidae, Reed Warblers and Allies) are Blyth's Reed Warbler (about 20%) and Clamorous Reed Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Booted Warbler is recorded against all the birds logged in Kozhikode (21 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.
