Finally, some decent swallows in flight

I had a tough time trying to track these fast movers. Finally this morning I was able to take some decent in flight pictures. I believe these are swallows ... but I can't tell what kind(s). I think there are more than one type of swallows in these pictures. Unfortunately, the harsh overhead sunlight this morning washed out the color, making it more difficult for me to identify them. I appreciate your help with IDs. Thanks.

Very nice

Well done Linh. I believe they are Purple Martins.

Wow those are fantastic shots! Extremely beautiful series. You did a great job with the whole set.

Thank you, all. I was glad that I could capture those fast movers.

Wonderful captures Linh.
