Brown Falcon
Falco berigora
The following is extracted from the Annual Bird Report for the twelve months to June 2017.
Uncommon, breeding resident
A resident of grasslands and open woodlands.
General: More records than usual, 160, including 3 WOO, though the reporting rate of 1.1% against the 30YA of 3.4% tells a different story – a 67% drop, to the lowest value recorded. Recorded from 74 widespread grid cells over 48 weeks in numbers ranging from 1-4, average 1.2, median 1. Max 4/13 Aug Wollogorang Lagoon U03 (LaK1). Winter accounted for 18% of records, spring 36%, summer 30% and autumn 16%. A somewhat lower figure for autumn and winter than usual. No breeding records. Breeding recorded in 14 of the previous 30 years. This species appears to be one suffering more than most from Canberra’s suburban growth.
GBS: Only one record, 1/ 2 Oct Giralang GrK12 (McD4). Even given the fact that this falcon is not an urban bird, this is an exceptionally low return, compared with, for example, the 26 records in 2001.
Abundance is the average number of birds of that species per survey. Where the species was observed (presence recorded) but the number of birds seen was not recorded, this is treated as a count of zero.

This map shows the observed distribution of the Brown Falcon for 2017.
The red circles are the grid cells where Brown Falcon have been reported.
The transparency of the red circles indicate how many surveys sheets were submitted for that grid cell; the darker the red the more reliable the data. Of the 315 grid cells with reports, 83 had only one sheet; an example is grid number B1.
The size of the circle represents the reporting rate. The maximum reporting rate for Brown Falcon was 100.0% (eg grid number B1) and the minimum was 0.2% (eg grid number K14). 
This map shows the observed distribution of the Brown Falcon for all years.
The red circles are the grid cells where Brown Falcon have been reported.
The transparency of the red circles indicate how many surveys sheets were submitted for that grid cell; the darker the red the more reliable the data. Of the 703 grid cells with reports, 55 had only one sheet; an example is grid number R27.
The size of the circle represents the reporting rate. The maximum reporting rate for Brown Falcon was 100.0% (eg grid number R27) and the minimum was 0.1% (eg grid number S13). 
This map shows the breeding distribution of the Brown Falcon for 2017.
The red circles are the grid cells where breeding activity for Brown Falcon have been reported.
The size of the circle represents the number of reports.
