Lincolnshire Wolds day out

in the 70's one of our annual March pilgrimages was to the Cwmystwyth area of central Wales to look at Red Kites, Common Buzzards, Peregrine, Raven and on the coast Choughs -- times do sometimes change for the better and a day on the Lincolnshire Wolds started off with a juvenile Peregrine, followed with a fine Red Kite then onto a spot where 18 Common Buzzards were visible in one scan of the bins with 11 in one group, two Ravens flew past and a short drive located another Raven playing with a party of Carrion Crows; later in the day Buzzards numbered 40 in total and another superb Red Kite flew past followed by 5 Kites at another location -- now all we need are some Choughs but guess that is a really long shot
