They use artist's illustrations to help exaggerate some of the identifying markings of birds that could otherwise be lost via improper lighting in a photo.
You can also generally get a list of common bird species in your area so you can go online and practice listening to their calls and looking at their illustrations/photos to get better at ID'ing them in the field.
