As it turns out, I found out later, these were actually white-faced ibis, which was another new bird for us. The white-faced ibis looks similar to the glossy ibis except for the white outline around the face, which is where it gets its name. The white-faced ibis is found in Mexico, parts of South America and the south western United States. They head north to their breeding territories in places like northern California, Colorado, Idaho, Wyoming and Montana during the summer. These ibis where searching the marshy grounds surrounding the river in search of insects to eat.
