My answer can be summed up in one word of two letters..."No"!
There are many positive reasons for my negative response, and here are some of them.
1. Some things are never the same.
It may be a different season of the year, a different time of day, a slightly different location. For example, I go to more than eight locations in the Bannerghatta biosphere, or visit two different sides of Anekal or Hoskote Lake. The birds and the flora that I see, may differ on each occasion.
2. Some things are the same.
Repeated visits over a short period of time results in familiarity with the terrain, and the local flora and fauna. In fact, this familiarity can sometimes extend to individual birds and plants. For example, I was able to identify, from a friend's photograph, a couple of Wood Sandpipers which I call "the married couple"...they stay together but are scrapping all the time!) from Anekal Doddkere. I have a particular place at the Ragihall sheet rock where,in season, I will find a rare orchid (Vanda spathulata). I know that there is a resident Short-toed Snake Eagle at T K Falls...and so it goes.
3. Some people in the group are the same.
It's great fun to go with people to the same location and see what's different, and what's the same, from the previous visit. More sets of eyes generally result in more sightings, sometimes of birds which are rare or not seen commonly. Sometimes it could be a learning about bird behaviour, like watching a Purple Sunbird repeatedly take spiderweb silk, or several birds nectaring on Palash or Red Silk-cotton trees.
4. Some people in the group are different.
Going with different people has been of immense benefit to me. Different perspectives and ideas result in my adding to my store of information and knowledge. I may look at a plant and admire its blooms, and be told that it is the host plant for a butterfly (eg, the Cipadessa baccifera or Ranabili with its beautiful berries, is the host plant for one of the largest moths in the world...the Atlas moth).
5.The secondary experiences are the same.
I have, over the years, made friends with many of the people who live in the locations I visit, and I like visiting them and keeping in touch; they often give me information about the local flora and fauna. For example, Saraswathi, Aswath, or Nagesh who live in Ragihalli keep me updated about the elephant situation, as also the water situation in the area.
6. The secondary experiences are different.
As a group, we may discover a new area that we have not touched before, or find things, large or small, that are new to all of us. We may talk to some new people who live in the area, and get different insights into life there. I visited Manjunath's home in Ragihalli while having our post-birding breakfast and saw the beautiful Varalakshmi puja which he and his wife Suguna had put up. I saw the Devi temple come up at Muthanallur lake, and the priest told me a lot about the deity, including the fact that the site of the temple was specially chosen to be near the ancient Mahua (Madhuca longifolia) tree.
Well...for all these reasons, and more, I am as happy to revisit a nature location as I am to go to a new one! This probably explains my seven visits to Arunachal Pradesh or my sixth visit to Satpura in Madhya Pradesh!
