After replacing Aishwarya Rai thrice - as the actress with most Internet downloads, ambassador of a jewellery brand and now as the Indian face of Barbie - 24-year-old Katrina Kaif has proved how young actresses in Bollywood are giving their 30-plus colleagues a run for their money.
Not just Aishwarya, Katrina has also replaced 33-year-old Sushmita Sen for an endorsement deal with shampoo brand Pantene.
Noted film critic Saibal Chatterjee says this is a "normal phenomenon" in the industry.
"Actors have a very short span of life as most of them start early and by the time they cross 30, the nature of the roles they get are more mature than candyfloss stuff. So the industry is always on the lookout for young blood," Chatterjee told IANS.
Other young actresses like Deepika Padukone, Kareena Kapoor, Priyanka Chopra, Sonam Kapoor and Genelia D'Souza too are walking away with the lion's share of films and brand endorsements in the industry these days.
Deepika has been cast instead of 35-year-old Aishwarya in Kalpana Lajmi's "Singhasan". She has also bagged the Bharat Sanchar Nigam Ltd (BSNL) ad from 34-year-old dimpled beauty Preity Zinta.
Like Katrina, Bollywood's size-zero girl Kareena, 28, nudged Aishwarya out of the Filmfare Top-10 Power list. And 'Masakali' girl Sonam Kapoor has succeeded Aishwarya as the Indian face of cosmetic brand L'Oreal.
After the success of "Jaane Tu...Ya Jaane Na", Genelia D'Souza has become a sought after name and replaced Preity and Rani Mukerji as the brand ambassador of Cadbury's Perk and Fanta respectively.
These apart, Kareena took on the mantle of doing a full-fledged role opposite Aamir Khan in "Three Idiots" after Kajol walked away.
"When Rekha and Hema Malini turned older, Madhuri Dixit and Sridevi replaced them. When the latter two became slightly older, Aishwarya Rai and Rani Mukerji took their place and now these two are being replaced by Katrina and Priyanka. It's a cycle - even these actresses will be dethroned some day," said Chatterjee.
Said Priyanka, who was cast in "Dostana" after Aishwarya declined the offer: "Age is nothing but a number. You can't generalise in terms of age, but no one in this industry is indispensable. Someone takes over from somebody. I have and I'm sure it will happen to me too at some point."
Apart from Tabu, Preity and Sushmita, a lot of the older actresses - Bipasha Basu, Aishwarya, Rani, Lara Dutta, Kajol and Shilpa Shetty - are making few appearances on screen.
While some say that they have made a personal choice to do just a few roles in a year, others like Shilpa and Preity are shifting gears between acting and business after they chose to be part of the cricket extravaganza, the Indian Premier League (IPL).
Preity, who recently featured in offbeat films like "The Last Lear" and Deepa Mehta's "Heaven On Earth", says she might get back to her bubbly, girl-next-door image, only if she gets a role with substance.
"I will do masala movies for sure, but I would like to have substance in them. I can't do just the glam chick any longer. I've been there, done that. It just doesn't inspire me any more. I have to leave that for the other girls to do. That's the way one grows," she had said.
But right now she has only one film in her kitty - Jahnu Barua's "Har Pal".
Tabu, 38, who has been absent from the silver screen after "The Namesake" and "Cheeni Kum", too has only one film "Banda Yeh Bindaas Hai". Similarly, Rani also has just one project in hand - Yash Raj Films' tentatively titled "Hadippa".
And 34-year-old Kajol, who drifted away from the scene after marriage, is doing only Karan Johar's much-hyped film "My Name Is Khan".
"I am not going to do four films a year. I will work, but at my own speed," Kajol had earlier told IANS.
After marrying actor Ajay Devgan in 1999, Kajol cut down on her film roles and makes occasional appearances on the silver screen.
However, Aishwarya's kitty still seems full - the Padma Shri awardee is shooting for Mani Ratnam's "Ravana" with husband Abhishek Bachchan, Tamil film "Endhiran" (earlier titled "Robot") alongside superstar Rajnikanth and Vipul Shah's "Action Replay" opposite Akshay Kumar.
The world famous Jim Corbett National Park, home to the endangered Royal Bengal Tiger, is a paradise for birds, with over 600 different species being recorded in the 1,400 sq km preserve. And where birds perch, can bird watchers be far behind?
Migratory birds such as Osprey, Ruddy Shelduck, Mallard and Gadwall, among others, come all the way from Europe and Central Asia to the lush green forests of the Himalayan foothills in this Kumaon region of the state, some 300 km from Delhi.
Many Himalayan birds also take refuge in Corbett during winters to escape the extreme conditions in the higher reaches of the mountain range. These include flycatchers, the Great Barbet and Wallcreeper.
Thousands of bird watchers from India and abroad visit Corbett during the winter to watch this spectacular congregation of birds.
"As few people are able to spot the big cats in the preserve, the birds have become a major attraction among visitors," says naturalist Ajay Ghale of Leisure Hotels, which runs the Riverview Retreat and Corbett Hideaway hotels in Ramnagar.
"The most sought after bird in Corbett is Ibisbill, a Himalayan bird, which migrate to the forest for three months from November to January. It is a very rare bird, and we only get to see five to six birds around the water bodies. Many people come here to watch this bird," Ghale told IANS.
"The Corbett National Park is a characteristic of the Himalayan mountain system. It offers a great diversity of habitats due to variation in altitude, relief, and temperature," says naturalist Sanjay Chimwal of Leisure Hotels.
Some rare birds found in Corbett include Orange-flanked Bush-robin, Blue-fronted Redstart, Brown Rock-Chat, Little Forktail, Orange-headed Thrush and Red-throated Pipit.
"I come here every year to watch the Himalayan birds. You find several species of aquatic and migratory birds in the Sal forests during winter. The most important thing is that as you travel to higher altitude from here (Corbett), you can spot more colourful birds," said Michael Sanders, a Italian bird watcher.
Realising the interest of visitors in bird watching, almost all the hotels in the area have included amateur ornithology in their tour packages.
"Twenty percent of our guests during a year are typical bird watchers. We host large bird watchers' groups during the winter," said Vibhas Prasad, director of Leisure Hotels.
