NP Rank:
Songbirds Duel and Make-Up With Duets
One new study has discovered that some birds fight with each other by singing - kind of like a West Side Story scenario. They use tweets to defend their relationships and territories against other birds.
Another new study however, shows that birds give each other sympathy with singing and help each other through the tough times - also like in West Side Story.
However to see how birds duel in song, it took some pretty extensive research and equipment.
The study, published in the latest issue of Current Biology, was made possible by eight microphones positioned strategically throughout the dense tropical forests of Costa Rica. The microphones fed the song duets of rufous-and-white wrens into a single laptop computer, enabling researchers to pinpoint the exact positions of the colorful songbirds.
"The first time I heard a rufous-and-white wren song, I was completely captivated by its voice," lead author Daniel Mennill told Discovery News. "They have low-pitched, flute-like sounds that are really quite beautiful."
Mennill, an associate professor in the Department of Biological Sciences at the University of Windsor, and colleague Sandra Vehrencamp conducted two experiments on breeding pairs of the birds, which can sing such closely matched duets that human listeners think they're hearing a solo performance.
They first recorded the birds in a passive context.
"This is analogous to recording you as you go about your daily routine of making your lunch, tidying your house, etc.," explained Mennill.
Bird couples also sing to defend their relationship and to let others know they are together.
In the other study it found that they sing to each other to commiserate when their team loses a contest, or a bird relationship breaks up (not kidding).
Green woodhoopoes, an African species, have been shown to bolster morale with group preening after rival gangs defeat them in singing contests.
The bonds between gang members intensified as rival threats strengthened. Leaders from each group of Phoeniculus purpureus redoubled their efforts to shore up morale after losing a contest against a neighbouring gang.
Andrew Radford, of the University of Bristol, who carried out the study, said it was the first time that animals other than humans had been shown to intensify bonding after a loss. He has reported his findings in the Proceedings of the Royal Society.
Dr. Radford said birds behave like 'football fans' who try to out-sing the rival team before a match.
“Rival groups regularly engage in raucous vocal displays, which are very similar to the chanting of opposing fans at a football match. When one reaches fever pitch, a flower or piece of lichen is often plucked and passed from group member to group member, much like the waving of a flag.”

i didn't actually see the hawk capturing the sparrow. The only thing I saw was the hawk flying over me with the sparrow, and then it sat on to that light-energy gathering device. I happened to be fortunate and have my camera and my long 200mm lens with me, that was the shot. I've caught several hawks around the Greater Boston area, and they seem to be quite well.

They get tired too. I watched this one for some time, and he appeared to 'yawn'. Perhaps he'd had a hard day.

This image was taken as one of a group of House Sparrows feeding in my back garden. They are daily visitors and are attracted by my bird feeding station.

Busy little sparrows are always fluttering about in an urban setting......waiting for the next crumb to fall from a person sandwich or child's cookie.

Every afternoon, hundreds of sparrows joyfully dance and sing from roof to roof, among several buildings. Everyday they do the same. It looks like a ritual.

The photos taken from my backyard, I like to watching them to visit my birdhouse. It helps me get object for my photography hobby, kind of take and give, I provide the seeds and they give me very natural poses.

These sparrows were only a few of the fifty or so that were flying in and out of the trees bordering a local pond. Although you couldn't see all of them, you could here all of them as they were very noisy chirping away and rustling around in the trees.

And lucid, inescapable rhythms;

This year I started calling a corner of our yard Sparrow's Corner, each year a the old and newly formed couples add to the families here. They definitely communicate like a big loving family! I watched and listened to the whole process of this last new brood of baby sparrows as they joined the large and existing family we've watched grow from the first year we put up houses and feeder. I watched and recorded the grandfather, his mate and his entire bunch. but notice he was always on alert looking for predictors and sending the warnings when he spotted a cat outside the fence. He was also there when the new parents were feeding the young, just sitting atop his house watching them and chirping to them.
The most exciting three days were when the time came to coax these babes out of the nest. I'd never seen it actually happening until this year. Watching the mother bring their food but not giving it to them, instead she would hold it just outside their reach from every possible position. As she did this there were chirps of encouragement coming from surrounding sparrows. The mother would make the same chirps each time she flew from away from her nest, as if to say, follow me. She did this non stop for three days, all day long. Eventually the two larger babes pushed the smallest one out as she was reaching for momma's bait, they'd grown tired of waiting their turn to beg for food from out of the small hole. The smallest started to fall but instinct took over and she made it all the way to the split rail fence where mom was waiting. By day three only one babe possibly remained in the nest, it was quiet though as all the Sparrows, seemed to accompany momma as she showed these little newbies around the yard.
I was watering a nearby hanging basket, thinking the nest was more than likely empty by when the largest of the three babies appeared at the hole. As I turned in surprise my hose followed; realizing too late and with a sinking heart I watched as the water hit this baby and caught it by surprise as well. Startled it began to tumble out of the nest righting itself in a most awkward position as it flew precariously to the fence. She didn't quite land, she more like stopped and hitting it kind of all cock-eyed went down into the bush below. I heard her begin to chirp using the same note she had when calling out for food.
I knew none of the sparrow families had been out back for most of that day, they'd flown over the house to somewhere out front much earlier. This baby, the largest of the three just kept chirping a single note and by chance another young sparrow must have heard her as it was flying solo when it arrived. It chirped back each time the baby did and they continued to go back and forth until the older sparrow pinpointedg its exact location. Flying down to it she chirped once again and left the baby flying once again back over the house from the direction it had come. Within minutes the mother arrived with the other bird and called to her baby, she too did this until she knew where the babe was locating it hiding under the bush.
I watched with hope and joy as this rescue played out; instead of flying down to her little one she chose to move only to a lower rail and continued to chirp in the same manner she had when she 'd flown away from the nest after they'd failed to take the bait food she'd offered and follow her. The same sound I'd heard for days imploring them to be brave and follow her. Sure enough the baby flew up to meet her on the rail, then up to the next rail she went and onto the top of the fence wire, she'd chirp and the little one would follow then she with the babe close behind went up and over the house. I was saved from guilt and left in wonder.
They had not returned to the nest since that time, weeks ago, but just the other day, (my camera inside:(), I was amazed again to see four sparrows on the hanging basket and one peeking out of the nest, she had two broods in there this year and I am sure all the other babes were near-by. They all were chirping as if to say, "Home, Sweet, Home" before they flew off and across the yard together.
Sparrow's corner is right off our Gazebo so we get to watch their lives each and everyday. It really is amazing and obvious to see that they are a community, and a very tight knit one at that.

It was raining and this baby sparrow was taking a shelter under a plant. I moved in very very slowly to make sure that I don't bother it and got a a chance to take a close-up shot. Isn't the baby just beautiful!

It's amazing what birds can communicate through song-if we could only analyze what all their calls mean how ahead we would be
I wonder what my song sparrow was communicating-I think happiness :)

I took my photo of a male House Sparrow in a grocery store parking lot in Salem, OR. To human ears the House Sparrow is very unmusical; giving a variety of chirps. Native to Europe, In the United States it is considered a pest. It takes over the nests of native songs birds causing their numbers to decline.

This House Sparrow was photographed in Yala National Park, Sri Lanka. Its a bird we usually see in home gardens but was surprised to see it in the middle of the jungle....the pair of birds came in side our jeep and was looking through the mirrors and getting rather excited...thinking they had a rival bird in their territory. This picture was taken when the Male sparrow rested on the spare tyre which was on the front bonnet of the jeep...

This bird make their nest by making a hole on a dead trees by using thei peck. A long of my witnesses I've never heard of any singging duel from them, only a simple tweet to show their present. Their size are smaller than sunbird but another species of woodpecker are bigger.

This Photo was taken at my balcony in my apartment in Amara, Eritrea. I am not really a bird photographer but it just came to me that during that season birds are aplenty. So i decided to set some food for the birds outside and positioned my Canon ixus point and shoot camera on a tripod, covers it with the curtain and waited. I heard a lot of chirping in fast flurries and when I took a peak, this Yellow sparrow was picking on my set. So I carefully positioned in and got some shots. There were times that other variety of birds came together with this one but they end up chirping their way to a fight of some sorts, which was difficult to shoot. I only wished I have my DSLR with me.

For some reason, when I took the picture, the sparrow wasn't afraid of people at all! That was a good thing for me - I was able to get an up close shot!
