"You can know the names of a bird in all languages of the world,but when you are finished ,
You will know absolutely nothing whatever about the bird.....
So let`s look at the bird and see what it`s doing --that`s what counts.
I learned very early the difference between knowing the name of something and knowing something."


-Nobel Laureate Richard P Feynman(1918-1988)

Ernakulam Heronry Survey 2019- Orientation Meeting



Wetlands in an agriculture-dominated landscape are known to support high bird diversity. Besides supporting bird populations these wetlands also provide ecosystem services in the form of cattle grazing, harvest of multiple wetland products (e.g., reeds, fish, silt, etc.), and water for agricultural and domestic purposes. These wetlands support non-breeding as well as breeding populations of water birds, including those that form heronries.Heronry birds are flagship species and good indicators of the health of the wetland ecosystem (Kushlan 1993; Frederick et al. 2009). Monitoring of heronry birds, hence, is useful in understanding the impact of pollution on the wetlands of agriculture-dominated landscapes and patterns off climate. The simple aim of the Heronries Census is to collect counts of 'apparently occupied nests' (aon) of herons, egrets and other colonial waterbirds from as many heronries as possible each year.

Many heronries hold a dozen or more nesting pairs, even a hundred or more, and occupy traditional, well-known sites that are active for many decades. Smaller and shorter-lived heronries must also be included in the counts, however, to ensure that the data represent the whole population. Even single nests of any of the normally colonial heron or egret species are relevant to the Heronries Census, even if only occupied for one season.

Changes in the numbers of nests over time are a clear measure of population trends. The more heronries that can be counted each year, the more certain we can be of population trends at national, regional and local scales.

Some of the traditional Heronries in Ernakulam District have been identified. But many more remain undiscovered.Therefore we need to make an all out effort to locate and identify as much as Heronries and we need as many volunteers to help us in this effort.
So please come to Mangalavanam on Saturday 11th May 2019 for a detailed discussion and  planning.

Ernakulam Heronry Survey 2019

Dear all,

In this time of severe, all around loss of biodiversity and the climate change, it is imperative that we try to preserve whatever habitat and , life birds such as waterbirds and herons who provide enormous ecosystem services to the community.

With an aim to do something in this direction we intend to conduct the survey of Heronries in Ernakulam district this year onward.
Towards this end a preliminary meeting is proposed to be held at 5 pm, at Mangalavanam Bird Sanctuary (behind Kerala Highcourt) on Satureday 13th April 2019.

All nature enthusiasts and in fact anybody  with interest and are willing willing to volunteer for this  survey are ivited to participate in the meeting wherein more information and rationale will be shared and the strategy to achieve this objective will be discussed.

An Appeal to the Management of HMT Ltd., Kalamassery Unit for protecting the Wooded areas of HMT Campus

Sri.S.Balamurugesan
General Technical Manager
HMT Limited,
Machine Tools Division,
HMT Colony P.O.
Kalamassery 683 503,
Ernakulam Dist.



Dear Sir,

Sub:-Film shooting at HMT Estate, Kalamassery- Disturbances to the area caused by the Film Unit.Reg



At the outset, we wish to thank you and the company for maintaining excellent green cover in your Kalamassery estate which comprise of diverse habitats like evergreen forests, shrub forests, grass lands, wetlands etc. Because of such a nature friendly eco system maintained by the company around 200 species of birds have been recorded by researchers and bird watchers from Kalamassery .The area is also rich in other flora and fauna. This green cover coupled with wet lands has also protected the water table of Kalamassery from going down and in fact there are wells in Kalamassery which supply drinking water to Cochin City. This has also helped in maintaining a lower atmospheric  temperature level in Kalamassery.The Kerala Forest Department has also recognized the bird diversity of Kalamasssery by releasing a poster ) mentioning 191 species of birds, including many endangered species.



In this context, we note with concern that some areas of the estate has been let out for film shooting and the people working for putting up sets for the film are doing so with total disregard for environment, cutting down full grown trees, using road rollers to level the terrain, where many tree dwelling and ground feeding birds are active. As per Indian Wild life protection act 1972 most of the birds are listed in under scheduled category and any offence towards listed species, habitat and nest is considered as hunting and punishable even if it occurs in a private land. It is the duty of citizens to bring to the notice of authorities any violation. However when some of our volunteers tried to point out the damage to the workers there, the retort was that they will fire crackers to drive the birds away or light fires and our volunteers cannot question.



Further there has been many wild fires in HMT Estate in recent time necessitating intervention of Fire force and people have to exercise caution while working there. However these film set workers have been smoking recklessly and also using electric cutting tools with sparks flying.



We also understand that these particular film unit has come to your company after they were denied permission by Forest Department in another area.



In view of the above we request your good selves to prevail upon these film people to exercise restraint and to be cautious in working this bio diversity hot point.



We once again thank you for your corporate social responsibility contribution in maintaining such a green and diverse campus, which is great benefit to the public at large.



Warm Regards,


Yours Sincerely,



Vishnupriyan Kartha.K
