2012-13 White-throated Needletail Report

So Michael, you mentioned in the report that some people have been sending
reports using "lots", etc, rather than quantifying the numbers. Maybe it
would help if you could send out a template for observers to fill in? Eg:
Site name,GPS coordinates, weather, wind, temperature, count, estimate,
area the flock dispersed over, etc? For example, myself and Ashwin
Rudder's sighting in the Hunter, where we counted 50 or so, but the flock
was spread over 10kms, which implied a huge count. Essentially, what data
(other than exact numbers) is most helpful to the study?

Cheers
Joshua Bergmark
