thanks Steve.

Interesting.
Map clearly shows "hot spots" at Lake Bathurst (presumably dry for the last 20 years or so). and Hall.

The "count of location" figures are really interesting, for they appear to show fluctuations approx 5 yearly intervals, then a huge spike in numbers (presumably numbers of locations, not total birds) in 2009, 2010.

I am not a statistician (or even the Bootlace of such an esteemed person), but I found that interesting.
Also confirmed my memory re the Airport as a former site of these birds (well I stand by that record), but you have confirmed they have not been reported from there in a very long time.

I just checked Dad's "Birds of the ACT: Two centuries of Change" and note with interest that he confirms they "had been seen for many years" at Canberra Airport, (ref. Taylor, Davey and Gibson 1986).
But interestingly, for such a conservative soul, he went on to declare them "presumed to be extinct in the ACT".
Alas, his call was premature - which is good for our sharp-eyed Geoffrey Dabb.

Map of the locations for Banded Lapwing currently in the COG database attached. Of the 237 records since 1974, none are at the airport although there are some nearby. Counts of the number of locations the birds were seen by bird year (ie July to June) below.
