Hi David
Birdlife Photography goes a step further: no use AT ALL of bird call playback for bird photography. (I have had to change my behaviour to conform).

'BIRD CALL PLAYBACK
Summary: Photographers submitting photos to the digital image library must confirm that bird call playback has NOT been used to attract birds for observation or photographic purposes.
Definition of ‘bird call playback’
The technique of bird call playback involves the use of any device, either analog or digital, that plays a part or full repertoire of bird song, which has been obtained either as a commercial product or recorded to a device for private use.
The evidence and issues for prohibiting this technique for attracting birds
The issues underlying the impacts of using bird call playback for observing and photographing birds are diverse and continue to be researched and debated. Call playback is an emotive topic, hence the arguments often raised to support the pro-case for this
technique are based more upon anecdotal observations and ‘emotions’ rather than the available scientific evidence. Nonetheless, there are data showing that call playback has an impact on bird behaviour and therefore has the potential to affect the well-being
of birds.
Why has BirdLife Photography prohibited the use of bird call playback?
- relevant scientific evidence;
- agreement with the ethical principles of other national and international ornithological/environmental organisations that have prohibited the use of bird call playback;
- adoption of the ‘Precautionary Principle’ until more evidence becomes available.
In summary, the current scientific evidence shows that:
- vocalisations, aggressive behaviours and territorial disputes increase in many species, even after short durations (minutes) of call playback;
- call playback affects mate choice by females in certain species and female nesting behaviour in other species;
- in species that do eventually habituate to call playback, this can be greater than 12 days even with constant call playback exposure, during which time birds expend energy and time not devoted to nesting, caring for their young, foraging, seeking mates
and/or adequately defending their territory.
Therefore, BirdLife Photography members must NOT:
- use bird call playback for attracting birds for observation or photography;
- engage in photographing birds that have been attracted by a third party using call playback; and/or
- encourage third parties to use call playback to attract birds on your behalf.
(A detailed document discussing several of the major studies involving call playback, the pro and con arguments and the implications of call playback on bird behaviours is currently being prepared; when completed, it will be available through our this
website.)
BirdLife Photography will continue to monitor publications and recommendations in this field of research to ensure that our policies remain updated and in the best interests of birds.'

Sorry to hear that you dipped in that sp, Martin, tho perhaps tomorrow's survey will be more productive ;-) There were none at my place today, either.
Did you follow the call playback protocol recommended as part of the BLA Ethical Birding Guidelines
http://birdlife.org.au/documents/POL-Ethical-Birding-Guidelines.pdf :
Call playback
The use of call playback can distress some species and may disrupt feeding and/or breeding activity. As a general rule, BirdLife Australia does not support the use of call playback for the purposes of bird observation. However, if artificial bird calls are
to be used they should be used for limited periods and be played at a volume lower than that of the target bird. It should not be used during the target bird’s breeding season.
The use of such devices should always be kept to a minimum, particularly in areas of high visitation by birders where call playback by other birders may well have occurred in the recent past. Responsible use of call playback can be valuable in locating cryptic
birds without causing serious harm; however, it is a skilled activity and should not be taken lightly. If in doubt, avoid using call playback, particularly during nesting season when birds may be called off incubation duties, or even abandon the nest altogether.
Cheers - David
