The species of birds seen in the BOS includes residents, summer visitors, winter visitors, passage migrants and vagrants. This page shows the species seen regularly in the BOS, that is those that have been seen almost every year from 2000-2019. There are currently 130 such species. For each species the following information is provided:

  • The number of years seen from 2000 to 2019
  • The number of months each year the species is seen. This helps to distinguish visitors from residents.
  • % Of Months - the percentage of the 240 months under review that the species has been recorded as being present. This provides an additional measure of occurence, though it is less accurate for species that we do not fully record. This figure is not provided for species we do not regularly record, i.e. very common species.
  • Records - the number of records we hold for this species since 1982
  • Max Count - the maximum number of birds seen in a 1 km square per day
  • 1km squares - the number of 1km squares the species has been recorded in. This gives a measure of the distribution. There are 1200km squares in the BOS area.
  • Rank - this is a number to sort the birds into Taxonomic order, as defined by the IOC

 Note that you can sort the list by any of the column values, such as by species name, by clicking on the column heading.

My Birding Patch - Alnmouth - the Northumberland coast in microcosm with Tom Cadwallender 

Having moved to the Alnmouth area in 1989 Tom has walked his patch for over 30 years.  During this talk we will look at the familiar, the scarce and sometimes the rare species of birds through the lens of diverse habitats and the seasons. Then a brief excursion to Coquet Island where we will look at some of the breeding seabirds including the Roseate Tern, a species which Tom has been studying and helping to conserve since 1991.  One thing is for sure the wonderful landscape and seascape of the Alnmouth area will feature quite heavily in this presentation.

Depending upon Covid-19 restrictions nearer the time this year's count may have to be posponed until restrictions have been lifted.  Please note further guidance will appear here and in the Newsletters nearer the time.

The Long Day Count is carried out by teams of observers in each of the twelve 10km squares recording the number of bird species seen during a maximum of 12 daylight hours on the second Sunday in May each year. Read more ...
