The purple heron (Ardea purpurea) is a wide-ranging heron species. It breeds in Africa, central and southern Europe, and southern and eastern Palearctic. The Western Palearctic populations migrate between breeding and wintering habitats whereas the African and tropical-Asian populations are primarily sedentary, except for occasional dispersive movements.
It is similar in appearance to the more common grey heron but is slightly smaller, more slender and has darker plumage. It is also a more evasive bird, favouring densely vegetated habitats near water, particularly reed beds. It hunts for a range of prey including fish, rodents, frogs and insects, either stalking them or standing waiting in ambush.
Purple herons are colonial breeders and build a bulky nest out of dead reeds or sticks close to the water' edge among reeds or in dense vegetation. About five bluish-green eggs are laid and are incubated by both birds. The young hatch about four weeks later and fledge six weeks after that. The International Union for Conservation of Nature notes that the global population trend is downwards, largely because of the drainage of wetlands, but assesses the purple heron's conservation status as being of "least concern".

Likely
About 50% of wildlife watchers report a Purple Heron sighting in Vasai-Virar on a given day, based on 610 verified sightings from GBIF citizen-science data. It is the 24th most-seen of the 217 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
January and November
In those months about 60% of wildlife watchers report a Purple Heron in Vasai-Virar on a given day, against about 20% in July, the lowest month. Those are among Vasai-Virar's driest months, with about 10 mm of rain a month against 840 mm in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Purple Heron sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 114
Of the 114 cities where we can rate Purple Heron sightings, Vasai-Virar ranks 3rd at about 50%. The best odds are in Denpasar (Indonesia, about 60%) and Ponnani (India, about 50%).
Same genus: Ardea
The closest relatives of the Purple Heron that you can see in Vasai-Virar (genus Ardea, Great Herons and Egrets) are Grey Heron (about 50%) and Great Egret (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Purple Heron is recorded against all the birds logged in Vasai-Virar (610 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.
