The Secret Life of Elephants

We have the pleasure of watching elephants in broad daylight in precious few places like Udawalawe, where they are habituated enough to be placid and tolerant of onlookers. Indeed, one can get rather spoiled in this particular Park, because even the birds are unafraid and will happily sit and pose for your clumsy photograph from inches away. At times, certain exhibitionist pachyderms even appear to put on a show for the gawking crowds:

But all is not paradise. Continue reading

Hyena girl meets elephant girl – A Chat for Skirts in Science

Some colleagues at the Denver Museum of Nature & Science have started a series featuring conversations by female scientists called Skirts in Science.  The goal is to make women in science more visible to students, especially young women and girls.

I had a lot of fun in this chat with Sarah Benson-Amram, now faculty at the University of Wyoming.  Here is a brief window into our work:

Many thanks to Paula Cushing, Kimberly Evans, and Marta Lindsay for inviting us to be part of this great series.  Check out their channel here.

Part 2 will have a discussion of how we came to do what we do. Stay tuned!

Dwarf elephant battles musth male!

16 June 2014 – S. de Silva

Battle1A clear sunny day, Lucy and Mickey are off in the park with Sameera while Kumara and I stay behind to catch up on office work. It’s mid-morning when Sameera calls to tell us Walawe Kota is back!  Walawe Kota is the nickname we’ve given the dwarf elephant of Uda Walawe.  This would be at least the third year now. What’s more, he’s in musth and reportedly fighting another male.  At first, the news is a bit confusing – there’s mention of a possible injury.

I’ve never seen him in the flesh though Kumara and Sameera have. I’ve only seen pictures and video clips, so I’m eager to try our luck. The park office reports he’s been spotted not far from the entrance, so we hop in our Jeep and dash off in hopes he’s still out in the open. Continue reading

An Evening With Elephants

Being A Better Scientist

I am trying out something new this month: I am hosting a fundraising event!

The event will take place on December 21st in San Francisco in the Randall Museum. We’ll show a BBC movie about elephants in Sri Lanka (trailer) and my friend Shermin de Silva will give a talk about her work with these same elephants.

Shermin de Silva

Shermin is an inspiring woman. She runs a field station in Sri Lanka, works in the United States (she is a postdoc in Fort Collins) and manages to raise enough money to keep her research going. This, as you can imagine, is not easy!

Her research is interesting, because she is one of few people who follows individual elephants in a wild Asian elephant population over time. Because she and her field crew know the individual elephants, they can see when elephant friendships form and break. It…

Asian elephants distinguish the calls of feline predator species

In September, Vivek Thuppil and Dr. Richard G. Coss from UC Davis published a paper in the journal Biology Letters regarding wild Asian elephant behavior towards pre-recorded tiger and leopard growls while attempting to crop raid. They found out that elephants silently retreat from tiger growls, but aggressively vocalize their presence when confronted with leopard recordings. According to previous research, tigers tend to prey on elephant calves while leopards are essentially harmless. This study is the first to investigate the inner-workings of elephant antipredator behavior at night.
