This appeared on 'Bucksbirders' last night, anyone any info? The aquaduct is of course the Iron Trunk at the west end of site.
02/5 17:00 : Redstart : Ouse Valley Park.
Thanks to Simon N on alerting me to pic on Buckinghamshire Bird Club website of this bird. Exact location not known could be west of aquaduct (Iron Trunk) so techically outside Manor Farm boundary but here is the link all the same.
