Severn house farm- Berkeley Power station bird sightings

Today there was a 10m high tide which was very nice to go and see as there was some hope for a rarity as Slimbridge WWT had 1 BUFF BREASTED SANDPIPER juv yesterday and also today. The major problem with Slimbridge's high tide roost for waders is that it's situated too low down so when we had this high tide today the waders where sighted but then as the "shaft" which they go on, goes underwater the waders fly north. With a buff breasted sandpiper in the flock I thought they might go south to the saltmarsh at Berkeley power station as it doesn't get flooded as much as the dumbles (the name of land where the waders roost).
So as I walked from the farm there was much excitement and I saw:

• 30+ meadow pipits- a huge influx of birds as they may have been grounded overnight but feeding metres away from me before taking flight
• 2 grey herons
• 30+ black headed gulls
• 20+ common gulls
• 3 great black backed gulls
• 1 pied wagtail
• 1 goldfinch
• Corvids
• 3 curlew
• 5 oystercatchers
• 20+ mixed flock of small waders. Mostly ringed plover and dunlin but will confirm the other odd ones by tomorrow.
• 7 mallards
