Maps & reports
The wealth of data that your BirdTrack records provide gives us various insights into bird distributions and movements throughout Britain and Ireland. The graphs can be found on the 'Explore data' page on BirdTrack.
|The reporting rate graph displays the percentage that birds are recorded on complete lists submitted to BirdTrack. The higher the reporting rate the more frequently it is recorded. It can also be used as a rough measure on how detectable a species is, with a low reporting rate indicating it is much trickier to see. The graph can be customised to country, subregion and years. You can compare multiple years by using the 'Add plot' function.|
|The peak count by week graph allows you to see the highest individual count of a species submitted for a particular week in BirdTrack. This graph can be customised by country, subregion, species and year, and it is possible to compare multiple years and species using the 'Add plot' function|
|The Recent sightings map is only viewable if you are signed in to BirdTrack. Here you can view sightings logged on BirdTrack in the last 3, 7 or 14 days. This excludes which are covered by the rare and sensitive species policy whose sightings are hidden on public outputs. The sightings can be searched by clicking on the cog wheel icon in the top right hand corner.|
The information presented in Maps & Reports is liable to change, as observers can amend their records at any time. In addition, although we believe all data are entered by observers in good faith, County Bird Recorders, Bird Club records committees and the BirdTrack Organiser do check and validate the records on a continual basis, and correct any errors that are identified. This process takes time and may cause subsequent changes to the information displayed in Maps & Reports on a particular day.

Migration blog – Winter
As we get ever closer to the end of autumn the pace of migration steadily slows, and as the daylight hours shorten so does the variety of birds on the move.
