小さなお客様 The small customer

駐車場に小さなお客様がいらっしゃいました。

奥はスズメで、手前は何の鳥でしょうか？
スズメより一回り大きく、グレーと白の羽です。

The small customer come into the parking lot.

You can see the sparrow on the rear side.
I don't know the bird's name that you can see on the front side.
The bird is slightly larger than a sparrow, and it has gray and white feathers.
