LatestNews

By posting news here you agree that your reports may be added to the LNHS database for use in the London Bird Report. A scalable map of the London recording area can be found here. Please list sightings alphabetically by site, following our standard format to assist automatic compilation of records into the database. Only report sightings of wide interest rather than listing all common birds (sightings of a more general nature may be recorded on the General sightings page). DO NOT post details of nesting by scarce breeding birds (those included in Schedule 1 of the Wildlife and Countryside Act 1981, as amended). Any such reports will be removed; please submit them instead to the appropriate LNHS bird recorder.

More London bird news can be found on Twitter by searching for sightings from many different observers using the #londonbirds hashtag or by visiting the London Bird Club page (no Twitter account is necessary for either).
