Spring tides provide new opportunities

The NW breeze freshened slight throughout the day. A dry and mainly sunny day.

Heysham Skear - low water 08:00 (MD)
Tonight's high water at 10.1m is the highest tide since March an is the second highest tide this year so far. Spring tides not only come a long way up the shore, they also go out a long way and today the skear was fully exposed. The waders seemed thinner on the ground, but that is because they were spread over a very large area. 
Little Egret 15
Red-breasted Merganser 2 (male and female together)
Great Crested Grebe 6 all adult in summer plumage 
Greylag Goose 1 flying north
Eider 4 - looks to be a female with 3 well grown young.

Oystercatcher c100
Redshank c100 - this was one large flock seen arriving, but then, as the other waders they appeared to be fewer than normal.
Turnstone c40
Dunlin 2
Knot 6 - 1 flew south plus 5 together on skear all still in partial summer plumage.

Swallow 3 together flying north
The low spring tide allowed access to the green marker post and it was repaired before the tide returned.

I thought this was interesting, the NW wind was blowing the low clouds across the south lakes hills, but as they reached the lowland or possibly the shore there were obviously thermal updrafts lifting the clouds to a higher level.
You can see the effect of two, quite compact, thermal updrafts in this shot

Mediterranean gulls 7 on Red Nab - 4 adult, 2 first summer and 1 juvenile. One of the adults was a returning regular visitor.

Juvenile Black-Headed gull with a small fish

These are Grey Mullet, they come in close to the sea wall on the rising spring tides to eat the algae that has formed on the wall and is dislodged by the rising tide.
