The eastern imperial eagle (Aquila heliaca) is a large bird of prey that breeds in southeastern Europe and extensively through West and Central Asia. Most populations are migratory and winter in northeastern Africa, the Middle East and South and East Asia. Like all eagles, the eastern imperial eagle is a member of the family Accipitridae. Furthermore, its feathered legs mark it as a member of the subfamily Aquilinae. It is a large, dark-colored eagle, with a resemblance to other members of the genus Aquila, but it is usually the darkest species in its range. It is an opportunistic predator that mostly selects smallish mammals as prey but also a fairly large proportion of birds, reptile and other prey types, including carrion. Compared to other Aquila eagles, it has a strong preference for the interface of tall woods with plains and other open, relatively flat habitats, including the wooded mosaics of the steppe. Normally, nests are located in large, mature trees and the parents raise around one or two fledglings. The global population is small and declining due to persecution, loss of habitat and prey. It has therefore been IUCN Red Listed as Vulnerable since 1994.

Rare
Under 5% of wildlife watchers report an Imperial Eagle sighting in Vasai-Virar on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 154th most-seen of the 217 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
January
In that month about 10% of wildlife watchers report an Imperial Eagle in Vasai-Virar on a given day, against under 5% in February to December, the lowest months. That is one of Vasai-Virar's driest months, with almost no rain against 840 mm in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Imperial Eagle sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 9 cities where we can rate Imperial Eagle sightings, Vasai-Virar ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Mashhad (Iran, under 5%).
Same genus: Aquila
The closest relatives of the Imperial Eagle that you can see in Vasai-Virar (genus Aquila, True Eagles) are Indian Spotted Eagle (about 10%) and Greater Spotted Eagle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Imperial Eagle is recorded against all the birds logged in Vasai-Virar (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.
