LNHS Recorders

A full list of the LNHS recorders for different taxonomic groups (or geographic areas for birds) can be found on the Who We Are page and contact details can be found on the Contact Us page.

The London Bird Records are being transformed from historic paper cards to an accessible digital dataset. London Natural History Society (LNHS) and Greenspace Information for Greater London CIC (GiGL) have launched 2 projects to enable volunteers to help us bring these records into the 21st Century. The projects don't require any specific bird knowledge and involve transcribing the historic cards. Find out below how you can get involved.

The history of the London Bird Records

Carrion Crow SQUARE 1The London Bird Records were first compiled in 1908 for London north of the Thames, (retrospectively from 1887), and in 1914 for London south of the Thames (from 1902). After these dates observations of birds were compiled annually. They were originally published in the London Naturalist, but from 1926 onwards published separately as the London Bird Report. The first set of records up until 1943 was compiled on foolscap sheets. In 1943 they were recompiled as part of the data collection for the publication of “Birds of the London Area since 1900”, which covered observations up to 1950 and was published in 1957. These records were also on foolscap sheets. From 1951 until 1987 submitted observations were recorded on 8x5 record cards. These cards were filed first by year, then species, then by vice-county. These records are hosted by GiGL, which is London’s LERC (Local Environmental Records Centre) and are the data custodians of the LNHS.

What we want to find out

Sparrowhawk SQUAREThe main goal of this project is to recover historic species data so that the information can be used by ecologists, conservationists, decision-makers and anyone else who is interested. This will improve knowledge of bird populations and distribution in London, and allow historical bird data to be made available for scientific research.

LNHS and GiGL have been working on these record cards so they can be added to our dataset of species in London. This collated dataset of information from hundreds of people informs decisions affecting wildlife in London and ultimately the conservation of species and habitats in the capital. 

Most of these record cards haven't been examined since they were first written by the original recorder, so you might discover something surprising!

Rose ringed Parakeet SQUAREThe LNHS recording area covers a 20-mile radius from St Paul’s Cathedral and the recording landscape has changed many times since the first record card was created.

Having transcribed the record cards covering the 1980s it was estimated it would take approximately 70 years to digitise all the cards without getting volunteers involved, so we need your help to discover what birds these 20th-century bird watchers were spotting.

We'd love your help to transcribe this data and interpret the diverse and idiosyncratic handwriting that only human beings can read and understand effectively. The transcription of these record cards will provide a huge contribution to the field of natural history, and particularly to conservation in London and surrounding areas of South-East England.

London Bird Records Zooniverse Project

The record cards have been scanned and indexed by year, species and vice-county. This gives very basic access but it takes a great deal of work to extract usable information. The data for the 1970s and1980s have been transcribed already, and the Zooniverse project is now working on the 1960s.

The Zooniverse website will show participants a scanned version of a record card (as demonstrated in the image below) and ask if there are any records in the image, before asking the participant to transcribe the data into an online form next to the record. The same card may be shown to multiple participants to verify the transcriptions. The project has been a huge success to date, and over 2,000 volunteers have participated to the project and completed over 5,000 classifications in total.

London Bird Record 50 Project

1950s Bird Record CardThe London Bird Record 50 Project involves transcribing card scans of cards from the 1950's onto an Excel spreadsheet so you should fee comfortable working with that (any compatible spreadsheet can be used so long as it can open and save in Excel format). Volunteers will be e-mailed batches of 20 card scans, an Excel spreadsheet with the required fields for transcription, and a set of instructions, all in a zipped folder.

20 cards should generate around 200 entries in the spreadsheet. Some spreadsheet fields are validated (you can only enter pre-set values) to help with consistency of entry across the project, and there are lists of names of sites and observers to help with illegible entries.
