Thanks Brian for the blog re the terns. Called in to LCyd for an hour or so this afternoon -and in for a treat - still 1 Arctic and 1 Common tern there at about 4.15, and 2 yellow wagtails (both male I think)on the bank to the left of the hide. Also 2 oystercatcher, Shellduck, female blackcap and good views of a reed warbler singing in the reeds in front of the hide, as well as the usual birds. A good number of swallows and sand martins too. Looked hard for the Mediterranean gulls mentioned on the sheet but couldn't spot them.
On a different note - please can anyone give me any advice re what to think about when choosing a new tripod for a scope? Have had a Velbon CX 640 tripod for some years now, since first having a scope, but find it is not very stable and I get a lot of 'wobble/shake' if it is extended upwards to any height or if there is a breeze. Also, I guess the fact that much of it is plastic may make it less robust. Would welcome any advice as to what to look for in an upgrade ( have been promised one as a birthday present, but don't really know the pros and cons eg aluminium/carbon fibre etc.) I'm sure individual preferences will vary but feel sure that many bloggers will have much more expertise in this field than I have. Thanks.
