I have seen on Twitter that quite a few birders are taking on the new 5MR birding challenge. That is birding / listing within a 5 miles radius from their home, so they are staying local when exercising.
Before that came about though, Alan Tilmouth, our NBNO or Northumberland Bird Network Organiser - a good job title I've just made up for him, set up a county 5 km radius patch list page that is currently trending on BUBO.
Out of interest, I thought I would compare the two areas directly to see if it would be greatly different and found this for my area -
That is some extension. If I was to take on the 5 mile radius, it would cover the local patches of Gary Woodburn in the North at Low Newton, Tom Cadwallender in the South at Alnmouth and Ben Steel / Dan Langston / Mark Eaton / John Rutter and myself in between.
Even though 50% is in the sea, the other landward half is a big area, a bit big to call it one patch really,as is the 5km to be fair, so I'll just stick with the original plan, even though I do frequently get about to the other places.
I am always interested in these type of geographical monitoring areas. Its a great way to learn about your 'own' wildlife. Usually I would treat zones separately so I list Howick, do regular birding at Boulmer, venture to 4 or 5 inland sites west of Alnwick for invertebrates and other forms but if I were to measure the whole range I watch for 90% of any given year, it covers no more than about 12 miles from home.
