This afternoon we watched for 45 minutes as a rough-legged buzzard decided to have a fly through Blacktoft Sands. It might of thought this would not be a problem but it quickly picked up a few marsh harriers. These decided that they didn't like this intruder and started mobbing it as it flew into the reserve from singleton direction. Very quickly the count of marsh harriers climbed to two, three then there were nine all mobing this rough-legged buzzard so much so that it went to ground at the back of first (for about 20 mins). Surprisingly, the marsh harriers quickly got fed up and gave up mobbing this bird. It then decided to have a second go at flying around right in front of first / reception before heading back towards singleton. This was a mistake! - the marsh harriers started mobbing it again. This time it left and was last seen heading west (I think).
On any other day at this time of year a male hen harrier would be the highlight of the day but not today. The male hen harrier appeared at the back of ousefleet at 1630 and was offering excellent views as the daylight faded.
These were two of the seven species of birds of prey recorded at Blacktoft Sands today. The rest were peregrine, merlin, sparrowhawk, kestrel and of course our marsh harriers.
Tonights roost had 10 marsh harriers, 2 barn owls and a merlin.
