Prince said she is worried there may still be more birds in the area who tried to find food or shelter and have not yet been found. Later Sunday, a separate caller reported finding a single bird a few blocks away, so Prince wants those who live in or frequent the area to be on the lookout. Anyone who finds an injured bird can call the Chicago Bird Collision Monitors hotline at 773-988-1867. They also should try to contain the bird in a cardboard box or paper bag until someone from the group can assist them.
