ok heres my experience on this day before yesterday i had gone to see some relative of my father from australia who was my fathers childhood friend i also went through the indias biggest sea link that is bandra worli sea link and then came to hinduja hospital nearby which was mumbai's magnificient sea shore.

the wind was over 15 kmph or a lot more whn i started to observe some of the birds


i saw they took of into the wind and always landed into the wind

second these birds (crows) used flap kind of things in their wing to help them glide

their wings to me seemed to be like uncambered ones

while the turned they used their tail as a v-tailed planed and turned it to stabilize their heading

while flying with the wind they tried to gain airspeed and gain altitude

while land to decrease their speed i also saw spoileron kind of things in their wings to slows them down

i still have  a lot to learn about these birds


it would be a lot helpful if any body could elaborate or correct my findings

sorry if there is a typo as my wirless keyboards battery is low

Last week we had around a dozen kites flying with the twin star .
One even attempted to attack it 

Adding posts guys

thats cool should have taken a video of the birds attacking a costly piece of equipmnt

not a problem with Elapor 

Then Venkat took over from us oldies and we were having some  dog fighting with the kites it was fun .
 
But they are far more agile and maneuverable  in air  as expected their lives depend on it .

Saju did not get out his camera fast enough so not my fault
