Birding (and more) in and around Mysore (Lingambudi Kere, Chamundi and Kabini), Feb 2021: Trip Report

Author: Ravi Kailas

Please see video for some highlights from this visit


Lingambudhi Kere (23rd Feb 21', 0720 to 1020)

 This south Mysore lake, located amidst a newly developing area of an expanding city, has the richest bird diversity among the city’s ebird hotspots. Not surprising given that it is an oasis of relatively pristine wetland and forest habitat (with some excellent patches of mature bamboo), in a yet sparsely populated suburb of the city. 

Entering through a nondescript gate in the East, a few minutes after sunrise, we were greeted by a cacophony of bird sound emerging from a large, fruit bearing Banyan Tree. Ticking off the usual suspects  - White-cheeked and Coppersmith Barbets and Indian Grey Hornbill, the most obvious this morning - that feast on this manna from heaven, in this part of the world, we proceeded along a trail with the lake on one side and farmland on the other, but not before the author was attacked by a colony of weaver ants, cunningly hidden in the leaf litter, that clambered up his legs, at least one finding its way into the unmentionables (in this forum at least) and making its presence felt, provoking a frenzied effort to ‘dust’ them off myself, in what must have been an awkward to somewhat humorous spectacle depending on the individual onlookers sensibilities. I digress, and getting back on track, this small, relatively open section of the path revealed a buzz ‘little brown bird’ (warblers/prinias) activity in the reeds along the lake/lower bushes, as well as some commoner wetland species, a flock of Western Yellow Wagtail, seemingly in migration, in a fallow field, an Asian Brown Flycatcher and birds like Ashy Drongo, Indian Golden Oriole, Common Iora and Small Minivet in the canopy beyond. About 200m further down, the path enters an alluringly deep, dark, bamboo forest, but not before passing an upcoming residential colony, and a stream of sewerage emanating from the development, flowing into the lake, suggesting a potential vulnerability for this relatively pristine green space in the not too distant future. Spot-breasted Fantail were numerous here, and there was also a healthy population of Tickell’s Blue Flycatcher, Blyth’s Reed Warbler and Indian Paradise Flycatcher (in in their magical breeding plumage). The highlights though, in the bamboo patch were of a Blue-throated Blue Flycatcher, a winter visitor to these parts, and a group of Tawny-bellied Babbler foraging in low bushes of an unkempt garden, where the bamboo forest met the outside world. Further on, bamboo gave way to an open forest of tall trees with a weedy undergrowth. This habitat produced sightings of Blue-faced Malkoha, and few wetland birds in the adjacent lake, including Garganey and Northern Shoveler (numerous) - our first ducks of the morning. It was around now, about two hours since we started our amble, with the morning sun bright and increasingly warm, when we started to wonder when we would complete the loop. We managed to stumble upon the much more popular and manicured gardens around the the main entrance to the lake, and some kind folks there pointed out the direction to a couple of other exits, one of it where our car was parked potentially, the farthest one as it turned out. Gathering pace, thoughts of breakfast vying for space with birds, and winning, we walked through a drier, scrubbier habitat where birds like Indian Robin began to appear. This led to a gate adjacent to a main road that hugs the lake that eventually led to our vehicle. Walking along this road produced our final species of the morning - two distant raptors riding the thermals of the late morning heat, which turned out to be a pair of the  delightful Oriental Honey Buzzard. 

An afternoon drive along the Mysore-Manathavadi Road (23rd Feb 21', PM)

One of the wonderful upsides of Mysore's location is the ease with which one can access biodiverse, wildlife rich natural areas, in the Cauvery basin of the Western and Eastern Ghats. One such place, 80km southwest of Mysore is Kabini, on the eastern fringes of Nagarhole Tiger Reserve. This relatively compact tourism zone is now world famous as one of the best places on Earth to see leopards, including, of late, a melanistic individual, and tigers, on a regular basis along with a healthy population of megafauna typical of peninsular India, its fame amply enhanced by its proximity to the social media wildlife photographer central that Bangalore is. With fame though, there is an inevitable deterioration of aesthetics, the zoo like atmosphere created by the clamour to see big cats, while ignoring...sullying even, the charm of the wilderness (glorious sunsets by the backwaters in summer, the grassy banks dotted with herds of elephant, gaur, deer., those refreshing April thundershowers, often accompanied by hail, the verdant forest after few monsoon showers, the charm of  spring, bird song, trees flowering in a leafless, brown forest, in the peak of the dry season, the misty winter mornings...). I reminisce here to my first visit to this wildlife haven, on a family holiday more than 30 years ago, to a time that there was only one resort, often with just two jeeps entering the forest in a safari session, when we could stop and smell the roses ... err.... carcasses, get excited by alarm calls and pug marks, stop under a fruiting tree to bird, spend an entire summer evening lakeside, watching the herds of elephants go about their business ... everything at a more relaxed pace, enjoying the jungle in its entirety. This became, still is, an annual pilgrimage for our family, every visit inevitably throwing up a rarity, at that time, a tiger seen across a watchtower, a leopard sitting out a thunderstorm on a tree branch across a game road, a pair of sloth bear crossing the game road at dusk, a Rock Python nesting in a hollow of a fallen tree trunk, but none of them as easy to find, often requiring patience and tracking/spotting skills, as necessary to find animals that would rather not be found. Over time big cat sightings have become more regular, virtually every outing these days, as families of felines habituated to tourist traffic (and to the big lenses pointing in their direction), making the Kabini experience what it is today. 

I digress though, and coming back to this opportunistic visit, a drive from Mysore and back the same evening, turned out to be more productive than expected. This road from Mysore to Kabini eventually connects to Wynaad in Kerala, but is not as prone to heavy traffic as the road connecting via Bandipur. As one would expect though, there is a lot more traffic on this road now than 30 years ago, and many of the idyllic villages along the road have turned into dusty towns. A village tank, with a healthy skirting of reed beds, between the villages of Hampapura and Madapura, however, has survived the test of time, with several species of waterfowl, including the migratory Garganey, along with Lesser Whistling Duck and Indian Spot-billed duck on display. Unlike in the good old days (pardon the frequent reference to the past), one needs to take a circuitous route, away from the forest, via interior villages to the Udbur Junction, where the road joins the forested stretch of highway. This lovely stretch of wooded road, onward from Udbur Junction, is closed for vehicular traffic from 6pm until sunrise and we entered with two hours to spare for our private safari, driving towards the Kerala border. February being the peak of the dry season, we entered a leafless, brown landscape, with sparse undergrowth and plenty of light entering the forest -all great conditions for wildlife viewing! Several herds of Chital and troops of Bonnet Macaque, the latter waiting close to speed breakers especially, in hope of handouts from slowing vehicles, were the first signs of wildlife. Enjoying the forest, and its subtle variations from mixed deciduous to riverine and teak dominated, in our hour or so drive, with a solitary Munjtac adding to the species list until them, we decided to turn back to beat the curfew. Minutes after the u-turn, excited alarm calls from Bonnet Macaque made us stop and scan the open jungle for the predator that was causing all this excitement. The culprit turned out to be a male Leopard, walking purposefully towards the thickets, through an open forest, lit in the golden light of the evening. This satisfying, somewhat unexpected (but we are talking about Leopards and Kabini!), sighting lasted about a minute before the animal melted into the undergrowth, at least as far as we could make out, but not from the macaques, which continued their frenzied alarm calls, joined in by Gray Langur keeping vigil from high in the canopy as well as a herd of nervous Chital by the roadside. With the highlight excitement of the evening done, the next 45 minutes or so through the forest road, produced a solitary tusker, Sambhar and Gaur - a healthy selection of mammals for a couple of hours informal safari on a main road! The drive back to Mysore was uneventful, except for the heavier than expected traffic, testing my skills to dodge oncoming traffic around corners, while being blinded by headlamps reflected off my rear view mirror/oncoming traffic, etc .... just another day on an Indian ‘highway’.            

Chamundi Hills (24th Feb 21', 0715 to 0845)

Chamundi Hills, an unmissable Mysore feature, was a tempting option for a relaxed morning of birding. Among what I expected to be a reasonable representation of birds to rocky, vegetated slopes in these parts, I was hoping to find Pied Thrush, a winter visitor to similar habitats in south India. It turned out to be a cool, pleasant, sunny morning, as I parked the car on the relatively busy road (with cyclists, walkers, an an occasional minivan), leading upto the temple from the city. A few minutes uphill, along the dry, sparse forest, with flowering trees adding a dash of colour to the landscape, and commoner birds like Yellow-billed Babbler, Cinerous Tit, Red-whiskered and Red-vented Bulbuls, India Robin, Pied Bushchat and a troop of Bonnet Macaque for company, a road, sign-posted to Nanjangud, appeared on the left. This much quieter stretch produced other common species, including several Tickell’s Blue Fycatcher, Small Minivet, Oriental Magpie Robin, Common Iora and a very approachable White-throated Kingfisher near a roadside temple with a dripping tap (the moist ground also a magnet for a species? of butterfly). As the morning warmed up, several Brahminy and Black Kites were seen soaring, but neither the Pied Thrush nor any rarities/migrants of note showed up on this modestly productive birding effort. This effort though, likely suffered from my lack of familiarity with the location and birding will probably be more productive with this knowledge.

Zeiss Victory Harpia 85, a brilliant spotting scope with smidgens of imperfection: Equipment Reviews

Author: Ravi Kailas


Some favourable alignment in the heavens (I expect), and Zeiss India's excellent customer service, had me in possession the Zeiss Victory Harpia 85mm, their absolute premium offering in their range of spotting scopes, for a few days, recently. My expectations, were high, given Zeiss's reputation for making stellar optics for nature observation and my own experience as a user of their 10x42 Victory T-FL binoculars. My first views through the scope were as per expectation - crystal clear, crisp views of backyard birds, including the richly coloured Indian Golden Oriole and the striking Loten's Sunbird, both relatively rare visitors to this space, among commoner subjects like Coppersmith Barbet, Rose-ringed Parakeet, Rufous Treepie. The images were tack sharp in the centre of the view, as one would expect of such high-end optics and while not quite as saturated or contrasty as the view through my Zeiss Victory T-FL binoculars, the colours were pleasingly natural, with no evident bias in colour temperature. It was effortless to discern the subtle colour variations and structural differences in feathers of various backyard birds, the intricate details of veins on the leaves of a Peepal Tree, the subtle variations in the buff, brown and grey tones on the Three-striped Palm Squirrel, the nuances of the head scale arrangement on an Oriental Garden Lizard - all pointing to the scope's ability to resolve fine detail at various magnification settings. The views were also amply bright (more on this later) and with adequate shadow detail (upto dusk/in high contrast situations). All told, this was easily one of the finest optics I have had the pleasure to look through, however, I had not yet discerned that special view that elevated it from a mere observation tool into something subliminal.  

For consistently magical views though, it took a trip from my backyard to a regular birding haunt, around a countryside lake surrounded by tall grassland and scrub. The scope really shone in this open habitat when its super wide field of view (63m-21m at 1000m across the 22x-65x zoom range, with a consistent 72° apparent field of view through the zoom range), became (oh so much) more than just useful. Whether it was watching a pair of Common Kingfisher or a White-eyed Buzzard, perched against the wide open, shimmering lake, a family of Little Grebe dabbling in the bright grey waters of the lake, Purple Heron on their hunting forays, tip-toeing against the background of tall grasses, subjects placed in the context of these wide-open spaces, popping out 3D like from the background,  resulting in engrossing images accompanied by the sounds of nature, only interrupted by an inner voice which kept repeating the term '"wow". Then there are practical upsides to this wide field view, including the ease with which one can follow flying birds, like terns, with minimal panning or having surprise visitors emerge into view, as has happened to me, in one memorable example, of a glorious, male Red Munia appearing into the view, while I was looking at a detail-rich view of a Plain Prinia, allowing me to enjoy this attractive spectacle just by turning the focus ring. This environment also allowed for testing the ability of the scope in highly backlit situations, where, for example, I was duly impressed when I could make out the faint suffusion of yellow on the throat of a Chestnut-shouldered Petronia, perched on a wire about a 200m away, heavily contrasted against a bright sky. Another situation where the scope proved invaluable was when I visited a brackish lake and the ease with which I could make out patterning/markings on the wings/body/face, the colour of the legs/beak, the plainness (or lack of) of the underparts etc, of distant waders, most in non-breeding plumage, all nuances vital for identifying this group of birds - more vindication for the scope's ability to resolve fine detail. 

Unsaddled by the zoom mechanism, the eyepiece is compact and easy to look through

Ergonomically, this full size, seemingly robustly armoured, weighty but well-balanced (I could handhold quite easily for short bursts of viewing), waterproof scope was a very easy to look through, with or without eyeglasses, with a fair latitude for the angle of the eye placement. A novel design on the scope body, incorporates the focus mechanism adjacent to the zoom, making it convenient to use both features with one hand, while looking through the compact eyepiece. The focus ring is geared, allowing for an intuitive to use quick and fine focussing mechanism based on the speed at which you turn to ring. Barring the tightness of the zoom ring (which I expect, will ease over time), the scope was so easy to use (especially mounted on the Manfrotto MVH502AH fluid head, which balances the scope perfectly and allows for ultra-smooth panning movement, and a robust tripod), that the physical set-up was barely noticeable, as should be the case, allowing me to enjoy the scope's stellar optics, unfettered. 


The the zoom and focussing rings are conveniently placed next to each other

All, however, was not perfect, and this scope displayed a few optical imperfections as well. For example, edge sharpness at its widest magnification suffered noticeably, and there was evident chromatic aberration towards the edges as well. However, as wide as the field of view is and as far into the edges that these imperfections occurred, it never really practically affected my viewing experience in any situation I found myself in. Also both chromatic aberration and edge sharpness improved with increasing magnification, the former virtually disappearing at some point. There was a smidgen of chromatic aberration, even in the centre of the view, in such extreme situations, such as viewing an all black, male Asian Koel against a bright, white background, but this too showed only at the widest magnification.  However, perhaps the biggest limitation of the scope could be that its maximum exit pupil diameter is limited to 2.5mm, due to some quirk of design, the physics of that I do not understand, rather than closer to 4mm, as should have been the theoretical limit based on specifications (85mm objective and 22x widest magnification)*. While this was bright enough for everything I used this device for, I can imagine scenarios where I would miss that extra light reaching my eyes, such as when looking to id a bittern, amidst reeds, at the cusp of darkness or while observing a crepuscular mammal blending into its dark environment. For someone consistently using their scope where light is a limiting factor, perhaps other choices would make sense, but this would mean missing out on that brilliant 3D rendition within an encompassing wide field of view, on most other occasions, taking nature observation from the practical to the sublime, that this scope excels at. 

*I understood that the aperture of the scope widens with increasing magnification, making use of the full 85mm objective from about 35x or so, making the absolute light gathering ability of scopes equivalent to its theoretical limits at higher magnifications, and hence comparable to any other scope of similar specifications beyond this threshold. 

Disclaimer: I have fairly limited experience looking through premium spotting scopes, barring the Swarovski ATM 65mm with the 20-60x eyepiece, which my cousin (very kindly) loaned me for a few years. This was a very good scope, but never gave me that wow factor from its optics, which I have had the privilege of experiencing while looking through a couple of binoculars, especially - the Zeiss 8x32 Victory T-FL and the Nikon 8x32 SE. My current scope, a Pentax 65 EDA-II with a  Pentax 14mm XW eyepiece, provides a wide (fixed 28x), sharp, colour neutral image in good light, but has obvious limitations while observing backlit subjects or in fading light, as well as the finicky eye-placement it demands to enjoy the full image circle. I have never really looked through ultra-premium scope offerings Leica, Swarovski, Kowa, Nikon and the like, and as such have no basis for comparison for my experiences through this scope. Also, this is meant as a non-technical, end-user review of the scope and all impressions are subjective, as seen through the eyes of a keen nature enthusiast.

The travails of spotting scope shopping in India

A series of events, all associated with a search to upgrade my fairly good, compact, Pentax spotting scope to a full size model, with higher quality optics, led to Zeiss India kindly loaning me this Harpia scope. Based on reviews online, I had narrowed down my choices to Vortex Razor HD 27x65 85mm, Nikon Monarch 20x-60x 82EDa Fieldscope and the Zeiss Gavia 30x-60x 85mm, all mid-range full size scopes, with reputedly comparable optics, with only the variation in price, seemingly, a factor to consider. Vortex does not seem to market their scopes in India and Nikon does not market this particular model in our country. While Nikon does seem to be marketing their ultra-premium, albeit dated ED Feildscopes here, their unresponsive sports optics marketing division here put paid to any plans I had for considering these. Only Zeiss India, with their proactive marketing team, and quite excellent customer service as it turned out, got in touch and promised delivery of the Gavia within a reasonable timeframe, loaning me a demo piece of the Harpia, when delivery of the former was delayed due to COVID lockdowns in Germany. Another option I seriously considered, although priced higher than these offerings, was the Swarovski ATS models with their choice of wide-angle or traditional eyepieces. Here again I hit a stumbling block, when I found the local authorised dealers less than helpful with information about delivery times etc. The only premium spotting scope that I found readily available at the time of looking, was the Leica Televid 82mm (straight) with the 25x-50x, through the Leica India Store and their helpful staff  promised delivery of the angled version in 3-4 weeks (as tempting as this was, I had to pass, given that this was well outside my budget). I suspect India is on the cusp of becoming a large market for good quality binoculars and spotting scopes and it would be really useful for end users like us to have the ability to walk into a store, try a demo unit, before making a purchase decision or at least have an opportunity to interact with a well informed sports optics marketing team during the process (written in hope that someone reading is incharge of such decisions!).

For those interested, we have also written up a piece titled "Binoculars for Nature-Watchers", which introduces the nuances of choosing binoculars for this activity, as well as de-jargonises some of the language in this article. 

Digiscoping with the Iphone SE 2020 (no adapters*)

I found this set-up adequate to capture record shots, by placing the Iphone SE 2020 camera on the eyepiece without adapters, especially with the scope parallel to the ground or pointing upwards. While pointing downwards I had to manoeuvre the subject off-centre on the scope to get the subject on the phone camera, as the phone camera's lens did not capture the entire field of view through the scope. There was also little areas of distortion or black-outs in the image, which, however, mostly occurred only the edges, hence rendering a good % of images usable/adequate for uses like bird id or to for publishing on the internet (by cropping out the distortions). Some example images (all cropped to at least half the original size), with this set-up, below:

Grey Heron

Jerdon's Bushlark

Whimbrel

Asian Koel

Brown Shrike

Zeiss India mentioned that they were coming up with dedicated digiscoping adapters for the Harpia, at which point I expect this sort of set-up to more than just passable for wildlife photography.

Pulicat Bird Sanctuary, December 27th 2020: Trip Summary

Author: Ravi Kailas (ficustours@gmail.com)

Pulicat is India's second largest brackish lagoon and a wintering and staging ground for numerous waders and waterfowl that use the Central Asian Flyway, with records of globally significant bird species like Asian Dowitcher and Crab Plover known from here. 

Common Greenshank


Date: 27th December 2020

Having neglected birding around Chennai over the last few years, almost exclusively to avoid the drudgery of the unpleasant commute, to get to anywhere resembling a pristine natural area, I have been recently motivated to revisit some birding hotspots around the city, 'thanks' to the otherwise restricted travel opportunities during the pandemic. I recently picked up the courage to brave the roads, one late December afternoon, and head north from the city, in my puny hatchback, weaving my way through massive commercial vehicles, unexpected potholes, oddly placed police barriers, jaywalkers and shockingly unexpected appearances of two wheelers inches from the front bumpers - in other words, an average day on an Indian highway - to Pulicat Lake. 

Admittedly, the aforementioned mayhem lasted only for the first of the two hour drive to the to eponymous town of Pulicat, located where the Kosatalayar River meets the southern fringes of the lagoon, part of the small area I explored on that day. Turning off northeast, from the highway connecting the city to the Ennore Port, from the town of Minjur, led into a countryside of villages, verdant paddy fields and myriad lily ponds (one especially large, near Kaatoor) and on a relatively empty state highway - a shockingly pleasant change from what was, until then. Bird diversity also increased, and included Ashy Wood Swallow, Grey Francolin, Tri-coloured Munia, Black-shouldered Kite and more, amidst the paddy fields and numerous Pheasant-tailed Jacana, Fulvous Whistling Duck, Eurasian Coot and Barn Swallow in and over the tanks. Turning East from this road onto one connecting to Pulicat town, there was marsh on either side of the road, inhabited by species like Eurasian Marsh Harrier and Asian Openbill. The vegetation progressively thinned, while approaching the shores of the brackish lagoon, and waders, mostly Little Ringed Plover, Pacific Golden Plover, Common Redshank, Ruff and Wood Sandpiper, and 1 Eurasian Curlew, all winter visitors to these parts, started showing up, furiously dipping their bills into the shallows of ephemeral pools on the fringes of the lagoon. These pools also attracted a feeding frenzy of mostly Whiskered Tern (with a couple of Gull-billed in the mix). Driving via the crowded market of the town, towards the confluence of the river and the lagoon, a couple of keen-eyed (fishing) boatmen waylaid me to offer into the lagoon, to see terns and gulls (suggesting that the water levels were too high for most waders at this time and Feb-April are better months for these migrants) - probably a decade old, alternative source of employment for these boatmen correlated with the exponential growth of bird photographers around major Indian cities, and hopefully an incentive for local fishing communities to resist large-scale, environmentally destructive projects that are knocking at their doorstep. I did, however want to explore the lagoon's shoreline a little northwest of here, leading to a fishing village called Annamalancheri, and given the limited time on hand, took a rain check on the boat ride

Leaving Pulicat behind (both the town and lagoon), early in the evening, I retraced back on the road the connects the town of Pulicat to Ponneri, before turning North, onto a dramatically quaint country road, towards Annamalancheri. This single-laned,  and admittedly not so good for tired bones road, with verdant fields and village tanks on either side, accompanied some wholesome countryside birding. About 5KM from the destination, the lagoon appeared to the East lit up in the warm glow of the evening light. An inter-tidal patch, evidently at low tide, hosted a handful of Little-ringed (both in breeding and otherwise form), Common Redshank, Pacific Golden Plover, Wood Sandpiper and Ruff - all observed by yours truly in the most idyllic of settings and in glorious evening light. Driving towards the fishing village, the lagoon appears roadside with Common Greenshank, Ruff, Marsh Sandpiper, the relatively rare (in these parts) Bar-tailed Godwit among the commoner Black-tailed versions and Black-winged Stilt, all seemingly settling in for fast approaching darkness. The rest of the drive to the village, through scrub dominated by invasive Mesquite, while showing potential for terrestrial birds, was hastier than ideal given the late hour, as was the 2 hour drive back to Chennai, via the town of Methur, joining the National Highway 16 and its laden trucks etc, at nightfall .....
