Video: Drone Captures Amazing Humpback Whale Feeding Event on Camera � Focusing on Wildlife

Apart from their massive size, humpback whales are most known for their extensive, complex “songs” that male humpbacks use for communication. But, humpback whales also have some fascinating feeding behaviors that are also worthy of attention—particularly bubble-netting. This form of feeding behavior occurs when groups of about four to twenty humpback whales concentrate their prey—like herring or krill—in large groups by producing bubbles and vocalizations before lunging at them, according to the Alaska Fisheries Science Center, Auke Bay Laboratories.

In recent footage captured off Alaska, a drone caught this incredible behavior on film as humpback whales race along the water’s surface in search of their prey. Then, around 50 seconds into the video, members of a pod of these whales lunge from the water’s surface and trap their tasty meal. Other footage recently captured off Norway filmed similar behavior, though in a much closer view.

Apart from this fascinating feeding behavior, a recent study also found out that humpback whales work together when feeding at night in dark, deeper water. The study, published in Scientific Reports, found that the whales make “tick-tock”-like noises—which may be used as a signal to notify nearby whales that food is in the area, or to help draw one of their prey, sand lance, up from the ocean floor.

Humpback whales can grow up to a staggering 60 feet long and weigh up to 40 tons, according to National Geographic. They are distributed throughout the world’s oceans from subpolar to tropical waters, and make vast migrations each year to breed. Humpback whales are listed as endangered under the Endangered Species Act, though two populations are under review for delisting. Commercial whaling activity severely decimated populations, but humpback whales are said to be recovering today. Current threats include vessel strikes, entanglement in fishing gear, habitat degradation, and more.

Take a look below for a great view of this feeding behavior:

I thought these comments were also interesting, so we keep the audio in perspective:

A nice film, but the audio dub really could have been much better. It's very apparent that the audio used in the film is not original. The sound of waves lapping on a beach, when the whales are a considerable distance from shore doesn't make sense. Also, the sound was looped, so the seagull audio is repetitive, and the sound of the whales singing is also, repetitive, with the same whale sound playing over and over. 

With the crew possibly in a boat controlling the remote control drone, a better approach for audio I think, would be to take either a camera with a good mic, or an audio recording system, say like a "Zoom, H4, or something similar, and do several minutes of just audio recordings of that same location. Yes, there are other boats nearby, but that wouldn't matter too much. The most preferable option, is to do a stereo recordings with shotgun mics pointed in the direction of the whales from a boat at a safe distance, call for silence on the set, and record the audio.

It's easy to capture and record good audio separately from the film of the same footage of the whales feeding. It's also much easier to dub the audio in during post, and to manipulate the audio track so that it closely fits the activity of the footage. No one would be the wiser if done correctly. It's only a matter of synchronizing a few of the whales surfacing to breath . The gulls are of no consequence and recordings of them would fit regardless. The water sounds of the whales surfacing to feed would also be captured and easily be dubbed in to fit the footage... 

Whales, especially Humpback Whales do not sing while feeding. The sound of their singing would drive the schools of herring, or fish away, and even the krill they feed on would flee, so they do not sing at all when they are feeding. They do employ the "Bubble-net Feeding" though.

Very nice footage, beautiful overhead shots with the drone though. Thanks for sharing.

Familiar fauna

Maramallis dripping their white fragrance. At home and here in Abu Dhabi.

Little brown doves on the pavement, sparrows in the bushes, sandy beaches and Indians on the streets.

All familiar, in an unfamiliar landscape.

"Chasing Ice"

Published on Dec 14, 2012

On May 28, 2008, Adam LeWinter and Director Jeff Orlowski filmed a historic breakup at the Ilulissat Glacier in Western Greenland. The calving event lasted for 75 minutes and the glacier retreated a full mile across a calving face three miles wide. The height of the ice is about 3,000 feet, 300-400 feet above water and the rest 

below water.

The Blackbucks at GNP and Tal Chappar

My good naturalist friend Bhanu was at Taal Chappar, Rajasthan recently, and as I plan to go there in January, I have been following her closely!

These pictures below were just so magical, that I had to share them here, so I can revisit them whenever I want to.  It looked like a scene from some fantasy movie with a pair of mythical creatures,  and if I blinked they would be gone.

These are the beautiful blackbucks that the Bishnoi protect and why not. 

These were larger and with more widespread horns than the ones I had seen at GNP, and Bhanu informed me that the two were different subspecies.

North-western Blackbuck - subspecies (Antilope cervicapra rajputanae) found in northern India, from Rajasthan upto Punjab.

South-eastern Blackbuck (Antilope cervicapra cervicapra).

I look forward to seeing these beautiful creatures on the lovely grasslands of Tal Chappar. Thank you Bhanu!

A bird I never tire of seeing.  Its brilliant blue colourations even more striking in flight, with colours that would do a Kancheepuram silk weaver proud!

The Black tailed Godwits of Mangalajodi

Jan 12th 2014.

To the north of Chilika is a freshwater wetland - Mangalajodi.  A remarkable success story of conservation

The slideshow below, put out by the local NGO says it all.

We travelled from Barkul up north on the state roads of Orissa, and we could see evidence of the destruction of the cyclone Phaillin - trees fallen, boards knocked down and even electricity poles still on their side.

The driver told us that several areas here were without power for a couple of months. 

And life goes on.

We turned off the main road, into a smaller village road,  quiet and dusty.  Nothing much going on.  The local kids eyed us curiously.

We arrived at the Eco Tourism Centre, and waited thre until it was time to leave for the evening boat safari.  We had a hot, delicious lunch there, though I now don't recollect whether we came back for it, or left only after lunch.

We gorged on these sour-sweet star fruits that Sameer obliged us by climbing the wall and pulling down with the help of the family that lived there!

Aditya in the meantime was befriended by this little flea-bitten cheerful pup, whom all the members fed with biscuits and chapatis, at the end of which he was so full he just rolled over and went to sleep!

Opposite the Ecotourism centre was this "marriage" between the banyan - boro in oriya, and Peepul - oshtho.

a fallen tree

We walked through an orchard next door, where the barbets and drongos called, wheeled and flitted from one tree to another

 We climbed a nearby hill and had a lovely view of the area.

This calote eyed us beadily, refusing to give up his sun perch or be bothered by us.

 We moved along to the waterways and swamps. 

What a wonderful day it was. moving silently among the reeds paddled by the locals who were expert in spotting and identifying birds, I had many lifers -

• Black-tailed Godwit
• Yellow bittern
• Plaintive Cuckoo
• Jack Snipe
• Ruddy breasted Crake
• Bailon's Crake

And many familiar ones as well - purple herons, stilts, swamphens, sandpipers, egrets, terns, pintails, kingfishers, citrine wagtails, glossy ibis, pond herons, OBS, cormorants.

And the not so common ones - comb ducks, ruddy shelducks

But for me, I will always remember Mangalajodi for those Godwits.  Limosa limosa, they are winter visitors to the Indian subcontinent, supposedly near threatened, and vulnerable, but they were everywhere!

After the initial excitement of seeing them, they then became like crows and pigeons!  Flying, wading, roosting, squabbling, we saw them in all poses, up close and in singles, flying in huge formations in the sky, landing noisily in the canals.

These birds are monogamous, and even when they migrate across continents they arrive as pairs.  Reportedly, a strong case for "divorce" is if your partner does not show up at the migration ground in time!!

I wonder if all these "singles" are divorcees?!

...in flocks on the ground....

...doing sorties in the air.. their black tails showing us how they are different from the bar-tailed godwits.

Seen in the duller winter plumage

A jacana up close - kept a nervous eye on us

The shelducks were distinct and plump,  their ruddy feathers further brunished by the sun

Mixed flocks of ducks, godwits, and other waders

Egrets would fly by, always looking like they were in slow motion replay!

The buffaloes moved around clumsily, and would sometimes break into a lumbering run causing much noise and splash

Fishing nets were cast, and the poles gave these whiskered terns a nice perch

Looked like the Godwit was asking the Pintails for directions!

It really was quite idyllic.  And as we floated along, I daydreamed and felt like a lotus eater!

We got off for a bit on one of the bunds and walked on it for a while, from where we spotted the comb ducks

A grey lapwing skulked in a corner

While the OBS looked like it had found something interesting

The evening excitement was the Jack Snipe hidden among the reeds and a Bluethroat, just as we were about to leave, by the roadside.  A Ruddy breasted Crake scurried into the reeds and we almost missed the Bluethroat.  There were a pair of them.  "Did you see them?", was the stage whisper that went up, and there was a huddle on the bund road, as necks craned to search for this exotic pair of migrant visitors.

Most of us did, and we were a bunch of happy campers that evening back at Panthaniwas.

The group count for birds was some 130 species, I had seen about 81 of them.  I went to see Chilika, but discovered Mangalajodi. 

A day on Chilika

Jan 11th 2014

The train to Calcutta chugs past the vast Chilika lagoon, and it has always been my wish to stop there one day.  So vast is it, that the train seems to take forever to go past it, not that I mind.

So it was that we finally visited Chilika lagoon, alighting at Balugaon in Orissa, a sleepy little side station, the train running late as usual.

We phut phutted our way to the Orissa Tourism lodgings on the waterfront at Barkul, riding in autorickshaws which had seen better days, but with drivers who were cheerful and helpful.  We paid some ridiculously low amount - Rs 80 I think - far far below Madras rates and took over an entire wing of the motel/hotel.  It was dark, and I was all excited that the next morning we would see the lake.

When we awoke the next morning, I was bemused to find a huge children's play area and other such stuff outside our window.  The lovely lagoon beach had been taken over for people's amusement it seems.

A short walk down to the boat jetty and we were off on the lake in a motorboat.  The cyclone Phailin had just been through these coaastal areas, and we were warned that it had affected the bird life and bird arrivals.

8 am - It was a gloomy day and the sun was up but visibility was still poor because of the morning mist.  This is the southern part of the lagoon

Chilika is a huge brackish lagoon - more than 1,000 sq kms, and a provider of fishing livelihoods to fishermen like these.  Waist deep in many areas, when in the middle of it, it was like being stranded at sea, with no land in sight.

The egrets waited patiently for the fishermen's nets to be raised

The mud flats had patches of reed growing on it, and the light reflected off it beautifully.  A school of dolphins slid noiselessly by, but they were gone in a flash.  I was heartened that they were alive and well.

Nalaban island, seen in the distance was where we were kind of headed.  It is east, closer to the mouth near Naupada.  But it is a long boat ride away, and the fumes from the outboard motor filled me with a kind of guilt and remorse.  This is not what I had in mind when I signed up for this trip.  The birds were in plenty - coots, pintails, egrets.....

We saw a bunch of flamingoes on the island, two harriers attempted bombing raids on the birds below, unsuccessfully as long as we were there, a bunch of barheaded geese had flown in, and brown-headed gulls bobbed in the water.  This is the watchtower on the island, but we didnt go there.

5 pm -and it was time to return. 

He was croaking away that night, missing in our cities.

This argiope seemed to be missing a leg?  (I can only count 7!)

In hindsight, to visit Chilika, I wonder if it makes more sense to come in via the northern borders, to Satpada, from Puri?  I wouldnt reccomend the Balugaon route, as Barkul is also the jetty for pilgrims going off to the Kali temple in the lake.

When we were departing from Balugaon, it was on Sankranti, and the station put the wildebeest migrations of Africa to shame.  Train upon train arrived and disgorged loads of pilgrims who would move across the tracks, platform and station as a dark, murmuring shadow, emptying and leaving a quiet vaccuum behind, only to be filled by the next train!

Mangalajodi, the swamps to the west of the lake, were more enjoyable, and also resulted in a smaller carbon footprint.
