Bird flu was never heard by me

[suntrack2]

I have never heard about this sort of flu, but today in the world it was spread in the hens.

and I have never heard about any sort of flu to this "metalic bird" see in the photo attached here.( my cousin has sent me this picture)

I have a habbit since my child hood to give some pieces of grains by throwing in my court yard to the "home sparrows", today the home sparrows are substantially not looking sumptuous seating on the wires and fencing of the home, they are becoming rare very fastly, may be the global warming is the cause. ??
