First impressions of the Avifauna of Mudigere, Western Ghats
|
The many insect hunting explorations I have had the pleasure of undertaking all over India, in connection with my research project, financed by the Council of Scientific and Industrial Research, Delhi, have provided splendid opportunities to form impressions (though fleeting) of the bird life of these areas. I have already given an account of my birding in the Pindar Valley (Garhwal Himalaya) and I will deal here with my observations in a little-known area of the Sahyadri Range, more popularly known as the Western Ghats. Mudigere is a medium
sized village with a population of approximately 5,000 people, situated
at a height of nearly 3,000 feet and located some 35km west of the famous
Hindu temple of Belur, in the Chikmagalur District of Karnataka State.
It is known mostly on account of the plantations that surround it, mostly
of coffee, tea and cardamom, and since it lies on the Bangalore—Mangalore
highway. The weather is pleasant even in summer and it receives
around 80-100 inches of rain annually, some 40% of it falling in July
and August. The soils are acid loams and paddy is the main food
crop grown here. Besides coffee, tea and cardamom, citrus, sapota,
vanilla, cocoa, mango, pepper, cinnamon, pineapple, banana and jackfruit
are also cultivated. The forest is thick and luxuriant, though it
is being exploited in some areas, especially around Mudigere. It
can be called moist deciduous and abounds in a rich variety of tree species,
especially Dalbergia latifiolia (Rosewood), Pterocarpus marsupium, Artocarpus
hirsuta, A. lakoocha, Terminalia paniculata (and several other species
of this genus), Santalum album (Sandalwood), Trema orientalis, Lagerstroemia
lanceolata, Garuga pinnata, Bischoffia javanica, Diospyros melanoxylon,
Olea dioica, and several species of Ficus. Teak (Tectona grandis)
is not very abundant here. Exotic Eucalyptus spp. trees have been
planted and the common shade tree in plantations is an Erythrina.
A small Date Palm, probably Phoenix acaulis, occurs commonly on open grassy
land, devoid of forest. The Mudramane forest here is known for its
large stands of Sandal trees. There are many streams here and the
Hemavati and Yagachi Rivers originate from the hills nearby, emptying
finally into the Krishanarajasagara Reservoir in Mysore District a few
hundred miles to the south-east. The University of Agricultural
Sciences, Bangalore, has a Regional Research Station located at Mudigere.
It is about 150 acres in extent and most of the tree crops mentioned above
are grown here. I will divert a little here to write about the “Mystery of the Moving Crest” of the Yellow-cheeked Crested Tit [see Newsletter for Birdwatchers, 16(9): 2, 5 & 16(10): 15]. Mrs Sarah Jameson actually hit upon the explanation when she opined—“Perhaps the truth of the matter is that the crest moves about depending on the mood of the bird !” Field observational problems such as these have a perfectly obvious final solution, not finding a place in most bird reference books owing to lack of space and/or their seeming unimportance. If any of our readers have kept a Cockatoo (a bird typical of the Australian Biogeographical Region) as a pet, they would have hardly failed to notice the many positions the crest occupies, from absolutely depressed to extremely erect when the tips of the leading feathers point in a forward manner. They would also have associated this change of position of the crest with the temperament of the bird: recumbent in a subdued state and magnificently upright when excited and calling. Though I should think that the crest of the Yellow-cheeked Crested Tit does not assume a flattened backward position at any time, the ‘direction’ of the crest does vary in disposition and alignment, being controlled voluntarily by the bird, in response to its ‘moods’, if we can use that term. Such problems prompt me to impress upon all bird watchers the merits of maintaining a field notebook . . . . .oh ! oh ! there we go again ! Anyway, there are at least six very good reasons which I will enumerate in a future article of mine and return promptly now to the subject of this one. Around Mudigere and the adjacent open fields and clearings, the following birds reign supreme: House Sparrow, Jungle Crow, House Crow, Rufous Tree Pie, Indian Myna, Cattle Egret, Spotted Dove, Koel, White-breasted Kingfisher, Small Green Bee-eater, Black Drongo, Brahminy Starling, Jungle Myna, Iora and Magpie-Robin. A couple of White-backed Vultures were seen soaring above the village, and I must have missed quite a few other common birds of the open areas here, but having only two days to myself at this place, it will need more field work to compile a fairly representative list. Pariah Kites were conspicuously absent. Next morning we trudged downhill from the research station, in a southerly direction, passing Nimbemule, Haley Mudigere, Mudramane forest, and Hoysala village, to our destination, the Chitrakoota Estate, some six miles away. It took us a good four hours at a slow pace with frequent stops either for insect collecting or for bird watching. The Mudramane Forest, which we traversed, is a drier, more secondary type of jungle, with a large stand of Sandalwood trees, for which it is known. Halfway to the estate we stopped for a breather beside a bend in a small stream, flanked by a high bank on one side and soft, wet sand on the other. There was just a trickle of water and here and there along the stream thick grass grew on the exposed sandy bed. Here I noticed a couple of individuals of the nymphalid butterfly, Cirrochroa thais, called the Tamil Yeoman in Wynter-Blyth’s BUTTERFLIES OF THE INDIAN REGION (1957). These fast-flying, almost ebullient, orange-brown butterflies made their presence felt, alighting on the damp sand or on the bare, hard soil lit by the hot sun farther away from the stream. I captured both of them in my net but kept only one, releasing the other on account of its rather ragged, worn condition. Earlier, I had sighted some Malabar Tree Nymphs, Idea malabarica, floating about amongst tree tops in shady groves, at a height out of reach of my net. These graceful, almost apparitional Danaidae are local creatures, hardly common except in certain patches of thick, moist or damp forests. The common name is most apt, since they clearly show the attributes of wood nymphs, the delicate grace typifying the tutelary goddesses termed ‘nymphs’. By the way, if any reader possesses a copy of Brigadier W.H. Evans’ IDENTIFICATION OF INDIAN BUTTERFLIES (2nd edition, 1932), in good condition, that he/she could sell to me, I would appreciate hearing from him/her. As we approached the Chitrakoota Estate, I spied an Ashy Swallow-Shrike making aerial sallies from its perch on top of a very tall, leafless, Artocarpus hirsuta tree, after anisopteran dragonflies. It would return to its lofty perch in order to devour the hapless insect. Mr K.P.C. Thejasvi, who owns this coffee estate, is an extremely keen naturalist, besides being a very enthusiastic photographer as well. He maintains his estate like a veritable sanctuary for all kinds of wildlife, and, needless to say, the animals repay his concern for them by inhabiting the area both in numbers and in variety. Blessed with a critical mind, a curiosity of his habitat, and a home in idyllic surroundings, he has a large collection of his own wildlife photographs embracing orchids, fungi, insects, and birds, to mention just a few nature groups. Among these were some striking photographs of an Ashy Swallow-Shrike feeding its young. It was nearing
two in the afternoon when we reached the estate and it was only after
a simple but sumptuous lunch that we ventured out into his domain to sample
the wildlife. In one low-lying area behind his house where the path
crosses a small stream, he has constructed two obscure looking hides to
watch birds that come that spot in plenty, either for a drink or for a
bath. It was here that, in the space of a little more than an hour,
I managed to observe several extremely interesting forest birds.
As soon as we approached the hides, we could see that bathing was on in
full swing—rows of White-eyes lining up on the rootlets jutting
out from the bank for their chance to have a dip in one of the pools
in the stream, which was a little more than a trickle at most places.
Magpie-Robins and Yellow-browed Bulbuls interrupted the little White-eyes
for a quick bath. I also got a short but adequate glimpse of a Ruby-throated
Bulbul having a quick dip, all of the time Red-whiskered Bulbuls were
very vociferous in the thickets nearby. The sun slowly receded from
this part of the estate and in the reduced light I captured three Tree
Nymphs that were probably looking for a place to settle for the night.
I also spotted a White-throated Ground Thrush rummaging amongst the fallen
leaf litter, and then located a nest of a nasute termite (‘white
ant’), consisting of a dark, carton-like material built on top of
a tree-stump about 4-5 feet above the squelchy, soggy ground. I
had been attracted to this nest by a Rufous Woodpecker which I had frightened
off it. On closer observation, I could see that one side of the termite
nest was hollowed out by, in all probability, the woodpecker. The
‘soldier caste’ of the curious termites of the Nasutitermitinae
(Isoptera) have reduced mandibles, which are replaced, in function, by
a cone-like snout on the head, through which they squirt an irritating
fluid which serves to discourage their enemies. These termites were
found on the nest and I deduced that the woodpecker may have been feeding
on them. But why the cavity in the nest ? Was the woodpecker
excavating a nest hole for its young ? So far, the Rufous Woodpecker
has been known to feed and nest in the tree-nests of the ants, Crematogaster
spp., with whom they share a sort of peculiar relationship. Though
the HANDBOOK OF THE BIRDS OF INDIA AND PAKISTAN (Vol. 4, pp. 179-181)
does not mention its feeding on termites, Henry (A GUIDE TO THE BIRDS
OF CEYLON, p. 122) says it searches termite hills for insects. However,
the interesting question now is—does this woodpecker nest in the
tree-nests of termites ? A pair of these shy, but beautifully coloured
woodpeckers were seen hanging around this termite nest. Returning to the estate bungalow, we came across a Monarch Flycatcher flying to its sleeping place, and a Little Scalybellied Woodpecker to a huge tree in the fading light. We were reluctant to leave this treasure-house of natural sights, yet the blood-sucking mosquitoes, and the darkness which had fallen, compelled us to say goodbye. The drive back to our university guest house in Mr Thejasvi’s jeep was utilized in animated conversation and eerie tales of ghosts (funny how the human mind turns to these creatures of our imagination, in precisely such an atmosphere !). Soon we were bidding farewell to our host for the day, which had, indeed, been one of those unforgettable ones. Next morning I was on the bus back to Bangalore, my mind full of the wonderous events of the previous two days on this section of the magnificent Western Ghats of peninsular India. In the following list, all 36 birds (* = endemic species) seen during my trip to Mudigere are enumerated, along with their SYNOPSIS/HANDBOOK numbers and current scientific names, or the benefit of readers : 44.
