House Sparrow
Passer domesticus
ABR description
The following is extracted from the Annual Bird Report for the twelve months to June 2017.
Common, breeding resident
Introduced species of urban and semi-urban areas.
General: There was an increase in the number of records from last year (45%) and a 255% increase over 10 YA and a 393% increase in the 30YA. Records from a few more grid cells (10%) and all weeks. Reporting rate of 11.5%, almost exactly the 30YA. While there were some dips in the reporting rate – dropping below 10% in the period 1985 to 1989, and again between 2002 to 2009 – in the last 6 years the reporting rate has held steady at the current level. This contrasts with the abundance and reporting rate for the GBS survey (see below). The total number of birds reported continues to rise: 6812 this year is up 84% on last year and up 470% of 10YA and 779% on the 30YA. Max 60/5 Dec JWNR (GrB1), mean 5.2, median 3. Only 12 breeding records in 12 grids: earliest on/5 Sep (in Fairy Martin nests) Nelangelo TSR 48 (LeM1) and last cf/13 Jan Bibaringa (SmA1).
GBS: Decrease from last year with the abundance (A=2.2944) is at its lowest levels ever in the survey. In 1983 and 1986 the A value was above 8.0 and since then there has been an ever so gradual, almost constant, decline down to the present value A=2.2944. Average group size down to 7.7 from 9.4 last year, median 4, max 74/3wk Feb Jerrabomberra (HaL2). 13 breeding records from 4 sites (down from 39 records and 8 sites) commencing with nb/4wk Sep and concluding with nb/3wk Dec both at Crace GrK11 (LeF1).
Abundance
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.

Distribution map
Distribution - 2017
This map shows the observed distribution of the House Sparrow for 2017.
The red circles are the grid cells where House Sparrow 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 F5.
The size of the circle represents the reporting rate. The maximum reporting rate for House Sparrow was 100.0% (eg grid number F5) and the minimum was 0.3% (eg grid number K14). 
Distribution - all years
This map shows the observed distribution of the House Sparrow for all years.
The red circles are the grid cells where House Sparrow 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 S27.
The size of the circle represents the reporting rate. The maximum reporting rate for House Sparrow was 100.0% (eg grid number S27) and the minimum was 0.3% (eg grid number H25).
