Cliff Swallows(Red-throated) 崖燕(岩燕) 6Z2K4188-1

Dear all, hope you don't mind and I study not much,

Parking lot of lakes, when I capture Western Grebe.

Heard so many sound from Swallows.

Many times with cycle eat and soil, have no idea why, what for with helpful.

Have three kinds of them is Tree Swallow and Barn Swallow and Cliff Swallow.
