Early on in our visit this Water Rail appeared from out of the reeds & quickly flew across to conceal itself amongst the vegetation on the opposite bank. We've spotted Water Rails on two other occasions, one at Fairburn Ings on a cold and icy afternoon and the other at Rutland Water, neither occasion were we able to get a pic so I suppose you can consider this a photo first.
Then from the same hide we had our first of many sightings of Marsh Harriers ! We watched three birds at one stage!!! A friendly birder pointed out the initial bird and once we'd got used to their flight behaviour we spotted them from each of the hides we visited.
Lots more sightings of the three Marsh Harriers
I've just noticed that Paul was at Blacktoft Sands earlier today & has some lovely pics over at his blog Little Brown Job.
