Which birds in the guide are easier to hear than to see?

The nightjar is the clearest case. The guide says its presence is usually easier to establish by listening than by searching with binoculars: the male's prolonged churring song is a characteristic sound of warm summer evenings in open pine woodland, while by day the bird rests camouflaged on the ground or along a branch.

Redshanks often announce themselves first too, since their sharp, piping alarm calls draw attention before the bird is visible. Curlews give clear whistles and bubbling calls that carry across open country, and their plumage can make even a large bird surprisingly hard to locate. The hoopoe's repeated, low “oop-oop-oop” carries surprisingly well, and waxwing flocks keep in contact with fine, trilling calls.

The gabralker is the exception in the other direction. Its low, two-part “gab-ralk” call is subdued and given mostly at dawn, which, together with its habit of staying under the bank, makes it easy to overlook.
