American Robin was feeling too hot and so he opened his mouth, allowing more ventilation into his body. He would like to stay in the shade, but sometimes he realizes that there is more food in the sun. He seems okay.
Song Sparrow likes to feed near shallow water. Insects like to come near the water and Song Sparrow likes the insects and being able to touch the cool water, too.
Watch out Song Sparrow! Make room for Spotted Sandpiper. Yes, Spotted Sandpiper is also looking forward to the water. I guess that is why they are called waders!
Even Grey Catbird is eyeing the cool stream.
