The study of our local birds is the lifeblood of the BOS and we encourage all members to participate in bird recording, whether you are a complete beginner or an experienced birder. 

The BOS maintains a list of all of the species seen within the BOS observeration area - the Systematic List. This is used to guide the records submitted for each species. 

Information on the birds within the BOS is collected by a series of surveys and ongoing observations. See the Fieldwork page for further details.

Members receive a monthly newsletter containing details on recent notable bird sightings, along with other local bird related news. Historic newsletters can be viewed here: Newsletters

The charts on this page show the distribution of Tree Sparrows from the BOS monthly records, for the years 2016-2018 and 2009-2018. Use the page button at the bottom of the chart to change the range of years. Click the double-headed arrow button to enlarge the map.

The BOS conducted a survey of Yellowhammers in the first 2 weeks of July 2018 to determine their population abundance, distribution and breeding status. All members and the general public were invited to participate. Read more ...
