    In Chennai wetlands, we have observed Scaly-breasted at different times, in February 2021 the juvenile Scaly-breasted munia was seen near AARI. then we have not noticed any Scaly-breasted munia near AARI. but in June 2021 the flock of Scaly-breasted munia was crossing AARI in the evening time from west to east, in the morning also they may cross but we have not seen them. in morning time these four Scaly-breasted Munia used to visit the bush in front of AARI.

Cinnamon Bittern செங்குருகு (Ixobrychus cinnamomeus)

This bird was observed since March 2021, but it was very rarely seen, that too while flying away. They stay inside the bushes, if we go near to bushes they fly away... the earlier observations were from Medavakkam Lake. During those time they simply fly away and escape, I was not able to notice its characters properly hence I could not identify. This bird is very new to me so I need to check all its characters to identify it because I have never seen it before. this was happening till May 2021.

In may 2021 that miracle happened this bittern straight away reached the bush in front of our home. that is the time I could see it properly. when I saw the bill (peak) of this bird I recognized as it is a bittern, later found it was Cinnamon bittern. a couple of bitter was visiting our place to stay protected, which is the same place where Moorhen was hatched their chicks. But now White-Breasted Waterhen has occupied the place, hence after trying for two three days this bittern left that area.

Even though it was visiting nearby we could not take clear pictures because it was full of bushes, but on one day evening, we could observe a bittern in an open space. I was called by the AARI admin to take pictures and immediately I went and clicked a lot of pictures. it was giving a nice pose. for the first and last time, it didn't fly away after seeing me. it was literally seeing me by turning its neck but didn't fly. our recent observation confirms that they stay at the backside of the AARI building, where birds like Bronze-winged Jacana, The Eurasian Moorhen, White-breasted Waterhen, Grey-headed Swamphen have bred. I hope this bittern couple also will breed over there, it is in the center of wetland, filled with two Palm trees, Typha, and some thorny trees, The bush is thicker and safer except for the issues with snakes. 

Here are some pictures Cinnamon Bittern (செங்குருகு) for you to see...

யாரும் இல்லை; தானே கள்வன்;

தான் அது பொய்ப்பின், யான் எவன் செய்கோ?

தினை தாள் அன்ன சிறு பசுங் கால

ஒழுகு நீர் ஆரல் பார்க்கும்

குருகும் உண்டு, தான் மணந்த ஞான்றே.

கபிலர் (குறுந்தொகை 25)

In the above-mentioned Poem, the great poet Kabilar mentioned the characters of Bittern... 

Thank you all...

 Purple Heron செந்நாரை

                Purple heron is one of the most confusing heron, and most similar to the grey heron. There are some noticeable differences which helps in the identification. this birds have been observed at Perumbakkam and Medavakkam wetland areas (we have not visited Pallikaranai marshland).

                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, favoring 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 (source ebird).

                       This is shorter than the crest of the grey heron and does not exceed 140 mm (5.5 in). The sides of the head and the neck are buffish chestnut, with dark streaks and lines down either side of the whole the neck. The mantle is oily brown and the upper scapular feathers are elongated but not the lower ones. The rest of the upper parts and the tail are brownish grey. The front of the neck is paler than the sides and there are some elongated feathers at the base of the neck which are streaked with white, chestnut and black. The breast is chestnut brown, with some blackening at the side, and the belly and under-tail coverts are black. The brownish-yellow beak is long, straight and powerful, and is brighter in colour in breeding adults. The iris is yellow and the legs are brown at the front and yellowish behind (Source: Wikipedia).

              இது சாம்பல் நாரையை விடவும் சிறியதாகவும் இலேசாகவும் உள்ளது. இதனை சாம்பல் நாரையிடமிருந்து வேறுபடுத்திக்கட்டுவது யாதெனின் இதன் இள்ஞ்சிவப்பு நிற உடலே. வளர்ந்த பறவைகள் கருத்த பழுப்பு நிறத்தையும் கொண்டிருக்கின்றன. இவை குறுகிய வடிவிலான மஞ்சள் அலகினை உடையது. செந்நாரைக்கு உருவத்தில் மிகவும் அருகாமையில் உள்ள நாரை இவற்றை விட உருவில் பெரிய கோலியாத்து நாரை.

இவை ஆப்பிரிக்காவிலும், மத்திய மற்றும் தெற்கு ஐரோப்பாவிலும், தென் மற்றும் கிழக்கு ஆசியாவிலும் வாழ்கின்றன. எனினும் ஐரோப்பிய இனங்கள் குளிர் காலங்களில் ஆப்பிரிக்காவை நோக்கி வலசை வருகின்றன. ஆசிய இனங்களோ வடக்கும் தெற்கும் ஆசியாவிற்குள்ளேயே வலசை வருகின்றன.
