Smartphone apps that include recordings of birdsong are common and inexpens=
ive. Guides to birdsong used to be expensive, and published in CD format. =
Few birders went to the effort to copy the recorded material to a more por=
table form. Today, birding field guides are offered for smartphones and ta=
blets. This makes birdsong playback in the field a simple matter. =0D

Some authorities say frequent playback of birdsong can be detrimental to th=
e targeted bird species, particularly to rare species that occur in a limit=
ed area. Others say it's no problem. One professional birding guide I kno=
w says it's actually beneficial, since the male bird appears to vanquish th=
e mechanical intruder. But he works in remote areas in South America, wher=
e birds are rarely exposed to playback.=0D
