The Breeding Bird Survey:
The Breeding Birds of South Brent
A comparison of the results obtained during the
2014-2016 Brent Bird Survey with previously
published atlases of breeding birds in Devon
compiled by Barrie Whitehall
There was a particular focus on breeding birds in the third year of the Brent Bird Survey. This was initiated and led by Barrie Whitehall who has now created an account of breeding observations across the parish for 75 species. In addition he's compared the records from the BBS with those from Sitters (1977 - 1983) and the Devon Bird Atlas (2007 - 2013).
Below is the introduction to Barrie's report, the list of bird species it covers and a sample of the data and commentary from the report (for the Sparrowhawk). You can download the full report in pdf format here.
Introduction
The following information has been compiled from data submitted by Brent Birders during the
Brent Bird Survey conducted between the years 2014 and 2016, hereafter referred to as either the
2014-2016 BBS or just BBS. The survey was conceived to determine the species occupying the area
of Brent parish throughout the year. Brent parish covers a total of 52 one km squares although just
over half of those are edge squares where some of the square actually lies outside the parish
boundary. However for the purpose of the survey the whole of those edge squares was surveyed.
The recording of breeding by any species was an extra and considered to be an addition to the real
aims of the survey. However in 2016, the last year of the full month by month survey, some extra
effort was put into obtaining breeding information and an additional form was provided for
observers to specifically submit breeding information. The uptake of this part of the survey was
limited in terms of the numbers submitting information, however considerable effort was put in by
those who did submit information and some valuable data was obtained.
The author has collated this information and produced maps and written text for each species. At the
same time the two breeding atlas maps for Devon, the first surveyed for between 1977 and 1983,
referred to here as Sitters 1977-1983, and the second surveyed between 2007 and 2013, referred to
here as Devon Atlas 2007-2013 have been consulted and distribution maps produced based on the
tetrads surveyed that correspond to the BBS area. Again more than half of the tetrads are edge
tetrads, some only encompass one of the potential four BBS squares that could lie within them and
therefore the data might be misleading. A good example of this is tetrad SX66L which, whilst it
encompasses two BBS squares, namely 1 and 2, also contains Piles Copse which lies outside the
BBS area and is significantly different in habitat type from squares 1 and 2. The direct comparison
of BBS data with Devon Atlas data for this area shows many species absent because they only occur
in and around Piles Copse. However it was thought best to plot this tetrad along with all the other
edge tetrads and alert the user of this data to that potential for being misled rather than omit it from
the comparison.
During the compilation of data from the 2007-2013 Devon Atlas it was found that the data for edge
tetrad SX76F was also severely limited with only 3 possible breeding species being recorded and
non in the probable or confirmed category. This is obviously a gross under estimate of the breeding
status of species within that tetrad and should not be used to judge comparisons between the three
different surveys.
The following colour codes have been used on the maps to denote the breeding status of the various
species in either the tetrads used for the two Devon Atlas maps or the 1 km squares used for the
BBS map.
The following criterion as used by the British Trust for Ornithology and the Devon Bird Atlas were
used to judge the breeding status of the species.
Possible breeder: Species observed in suitable habitat, or singing male heard
Probable breeder: Pair in suitable nesting habitat, defended territory, courtship, visiting
probable nest site, agitated behaviour or nest building
Confirmed breeder: Distraction display, used nest or eggshells, dependant fledged young, adult
behaviour indicating an occupied nest, adult carrying faecal sac or food for
young, nest with eggs or nest with young seen or heard
The results have been plotted on spreadsheets in a matrix corresponding to the ordnance survey grid
covering the Brent parish.
A total of 75 species are mapped in the following document, these include 7 species that have been
lost or potentially lost as breeding species in the area and 6 species that have been gained as
breeding species in the area since the 1977-1983 Sitters Atlas.
The species that are no longer recorded as breeding or probably breeding in the Brent area are
Grey Partridge, Dunlin, Barn Owl, Little Owl, Wood Warbler, Ring Ouzel and Pied Flycatcher.
The species that have been recorded breeding or probably breeding in the Brent area either by the
time of the 2007-2013 atlas or as a result of the 2014-2016 BBS are Canada Goose, Little Grebe,
Kingfisher, Grasshopper Warbler, Lesser Redpoll and Siskin, although the Lesser Redpoll might be
breeding just outside the Brent area.
