going to isle of wight in late march on a work thing. hope to get a day or to birding in , any advice on the best place to go for max sightings . live in falkland islands so do not get to uk to that much:-O
Daily sightings with site guide and also archives of monthly sightings so you can look back to March and see what sort of places to go and birds to see at that time of year http://iowbirds.awardspace.com/IOW.htm
Birding blog of the IOW and other travels etc, also active birdforum member and I'm sure will give better advice than I. http://www.vectisbirder.co.uk/
Two places I would recommend at that time of year are West High Down/Needles area and St Catherines point area which is the southern most point. One of my favourite places is also Ventnor area with the downs at its highest point which is an open area and has great views and Dartford warblers. Also Newtown is always worth a visit.
As you can see we're quite well served by birding sites for a small island.
