The booted eagle (Hieraaetus pennatus) is a medium-sized mostly migratory bird of prey with a wide distribution in the Palearctic and southern Asia, wintering in the tropics of Africa and Asia, with a small, disjunct breeding population in south-western Africa. Like all eagles, it belongs to the family Accipitridae.
The booted eagle was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the eagle, falcons and relatives in the genus Falco and coined the binomial name Falco pennatus. Gmelin based his description on "Le Faucon Patu" or "Falco pedibus pennatis" that had been described and illustrated in 1760 by the French zoologist Mathurin Jacques Brisson. Brisson had examined a specimen in the collection of Madame de Bandeville who was also known as Marie Anne Catherine Bigot de Graveron (1709-1787). The booted eagle is now placed in the genus Hieraaetus that was introduced in 1844 by the German naturalist Johann Jakob Kaup.

Rare
Under 5% of wildlife watchers report a Booted Eagle sighting in Chennai on a given day, based on 231 verified sightings from GBIF citizen-science data. It is the 106th most-seen of the 223 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.
February and March
In those months about 10% of wildlife watchers report a Booted Eagle in Chennai on a given day, against under 5% in April to January, the lowest months. Those are among Chennai's driest months, with about 10 mm of rain a month against 290 mm in November.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Booted Eagle sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
28th of 60
Of the 60 cities where we can rate Booted Eagle sightings, Chennai ranks 28th at under 5%. The best odds are in Algiers (Algeria, about 30%), Kanpur (India, about 30%) and Marrakesh (Morocco, about 30%).
GBIF citizen-science records
It is estimated from how often the Booted Eagle is recorded against all the birds logged in Chennai (231 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.
