Birding website for Northants birders from Mike Alibone, editor of the Northants Bird Report. His "Northants Birds" website holds a host of up to the minute information on sightings of birds in the county and much, much more for beginner and expert alike.
Portland Bill Bird Observatory website. In my opinion one of the best maintained observatory websites (which also features other life forms!). Martin Cade puts so much work in as you will see! Also, you'll be surprised how closely movements at the Bill mirror what goes on in Northants, albeit a slight time lag.
