Grey-headed swamphen (Porphyrio poliocephalus) நீலத் தாழைக்கோழி Birds of Chennai Wetland / Marshland

 Grey-headed swamphen (Porphyrio poliocephalus) நீலத் தாழைக்கோழி is a species of swamphen occurring from the Middle East and the Indian subcontinent to southern China and northern Thailand. It used to be considered a subspecies of the purple swamphen, but was elevated to full species status in 2015; today the purple swamphen is considered a superspecies, and each of its six races is designated full species.

The male has an elaborate courtship display, holding water weeds in his bill and bowing to the female with loud chuckles.

The grey-headed swamphen was introduced to North America in the late 1990s due to avicultural escapes in the Pembroke Pines, Florida area. State wildlife biologists attempted to eradicate the birds, but they have multiplied and can now be found in many areas of southern Florida. Ornithological authorities consider it likely that the swamphen will become an established part of Florida's avifauna. It was added to the American Birding Association checklist in February 2013.

This couple of Swamphen is continuously observed in this site. they always sited in the same area. morning to evening they search for food... A very large bluish-purple gallinule with a red bill and forehead shield and red legs and feet with long toes. The tail is flicked up often, revealing fluffy white “underpants.” Juveniles are duller than adults and lack the red bill and shield. A common inhabitant of marshy, vegetated freshwater bodies such as swamps, rivers, and lakes; usually in small groups. Feeds, often clumsily, at muddy water edges, in reeds, and on floating vegetation. Makes short nasal grunts and croaking sounds.

A large purplish-blue bird with long red legs and large feet. It has a huge red bill that extends back into a red frontal shield. The white patch under its stumpy tail can be seen as it is flicked up at each step. It is fond of climbing up reeds and sunning itself early in the morning. It is usually found in reedy swamps and marshes, where it is seen in pairs or small parties. It stalks or skulks through the vegetation with a jerky bobbing of the head and flicking of the tail. It feeds on shoots and other vegetation, as well as insects and molluscs, and larger parties can be destructive in young paddy fields. The call consists of loud hooting, cackling and hoarse notes. In the breeding season the male has an elaborate if amusing courtship display. He holds up waterweed in his bill as an offering to the female, who he bows to whilst uttering loud chuckles.

The common moorhen /Gallinula chloropus, also known as the waterhen or swamp chickenதாழைக் கோழி is a bird species in the rail family (Rallidae). this bird spread across the Old World. 

The common moorhen commonly lives around well-vegetated fresh and brackish marshes, on ponds, lakes, and along slow-moving watercourses with bordering vegetation. Swims with jerky motion and walks with stealthy gait, the tail often slightly cocked; does not usually dive. Note big white oval patches under the tail and white streaks along flanks. The adult has a red bill with a yellow tip; the immature has a duller bill and legs. Smaller and more retiring than coot, and rarely far out on open water.

This post records the presence of this Eurasian Moorhen in Sivagami Nagar, Medavakkam, Chennai - 600 100. The currently observed bird is living in an empty plot where rainwater is stagnant and dense with Typha (Typhaceae, Poales) plant species.

We are observing this bird-couple since 1st February 2021 in this plot, most of the time they live in this spot only, whenever they are disturbed by humans or by other animals they ran and hide inside the Typha vegetation.

Even though they run away from humans and dogs they don't have fear towards snakes. they voluntarily search and fight with snakes.

This video was taken in another place that is also near to this plot but there the couple is different. they were literally chasing, searching, and fighting with that snake. even though the snake ran and hid, these birds didn't let it go... they were waiting and searching continuously until the snake came out, watch the video to know more...

Eurasian Moorhen build their nest using the dried plant parts, here in this case they built a nest with the Typha plant parts. it was surprising for me that, one bird was searching for food for another one which was incubating their eggs.

One parent moorhen was continuously sitting on the eggs to incubate them until hatching of eggs. The day they laid eggs was un-noticed hence could not say how many days they incubated their eggs, But the Moorhen chicks were first 08th March 2021. First day evening two moorhen chicks were noticed on another day we noticed five moorhen chicks.

The Moorhen chicks are so cute and with full dark black hairs/ feathers which were absent only on the forehead of the moorhen that gave them the elegant look. 

In this picture, one could easily check the morphology of the Moorhen chicks. their cute feathers and bald head with red peak are clearly visible (Photo credit: U Elaya Perumal).

Since these are so small, their parent Moorhen search food for them in the water and then they feed them...

This is our small contribution towards the Chennai Marshland Biodiversity and to the Eurasian Moorhen / Common Moorhen.
