First time car hawking alone.

Well I figured it was time to give it a shot since this was the main reason I got him. After putting Abby in the box I got Biggio out and we drove around the park. I spotted a pool of water where there were grackles and sparrows. I pulled up to the pool, lowered the window and Biggio flew out the window and dove at the birds, but I think I did it wrong and he missed. I called him down to the lure and we drove to a wal-mart and tried again with the same result. It was about sunset now and I could not find any more on the ground. I was hoping he would have been about 20 grams lighter.
