No wind. No tide. No good!......well, not much good

Almost breathless, what air movement there was came from the south. Overcast and warm till mid afternoon then the skies cleared after a short shower. Then sunny and hot.

Middleton Nature Reserve 
Some shots from Janet:

Swallows bathing

Male Common Darter

I just did a quick check of the main pond late afternoon (MD)
Mute Swan pair plus 7 well grown cygnets 
Coot 6
Moorhen 1
Mallard 5
Little Grebe 1 in summer plumage, dived as soon as it saw me and didn't surface in view again. First one seen in quite a while
Cetti's warbler 1 singing from "no swimming" pond

Common Darter 3
Migrant Hawker 3

This time last year we fixed a branched post in the NE corner of the pond, hoping to attract fish eating birds. Today, it did just that, but not exactly the target species!
Grey Heron perched on top of the perching post.

Heysham skear - low water 14:30 (MD)
Low water today was only 3.4m. This morning's "high" water was 6.8m. So the tide moved a total of 3.4m in 7 hours! I've seen bigger waves!
No Eider.
Great Crested Grebe 1
Red-breasted Merganser 4 - what I took to be a female with 3 immature flew in together.
Then started feeding

Little Egret 6
Oystercatcher c300
Curlew c150
Redshank c150
Turnstone c60
Knot c800 - it was nice seeing flocks of Knot flying around again. These are two of the four main groups.

They often just rest on the skear, but today they were actively feeding, and seeming to find food easily.

Dunlin 2
Ringed Plover 10 restricted to a small area of inner skear near the Sandylands groyne, that remains mussel free.
Black-Tailed Godwit 4 - a single bird plus three together. All in fading summer or juvenile plumage.
This is the lone bird. The Herring gulls continue to find some small mussels

It flew off to the middle of the inner skear

Two of the three together, one clearly showing its black tail
These are all three.

Early morning Merlin

A very light east breeze till lunch, when it freshened slightly and shifted to west. Bright and sunny after a hazy start.

South shore
Janet had an early morning walk along the sea wall
Oystercatcher, silhouetted by the sun's haze through the Saharan dust

Red Nab Robin

Red Nab Rock Pipit

The outflows were busy, this is No.2

Curlew 

Oystercatcher(s)

Redshank 

Grey Heron - more on this later

Cormorants on wooden jetty

This Merlin flew high over the harbour. 
Not easy to get a shot of these, they do fly quickly 

I had a walk along the wall later in the morning (MD)
Timed to watch the beach by the wooden jetty become exposed but the only gull to turn up was
Mediterranean gull 1 second calendar year
2nd calendar year Mediterranean gull

Pink-Footed goose 55 flew SE over the harbour at 10:15. Mark Jones picked them up as they left the recording area, 4 broke away and headed up the River Lune while the others continued south.

Grey Heron, there were more around than the usual single bird today. Janet saw two, I saw three including this juvenile that was chased across the harbour mouth. 

It might only be young, but it had excellent balance, better than mine trying to film it! I suppose you need extra long legs, when you have an extra long neck to scratch.
Wheatear 3 - 1 at lighthouse and 2 on foreshore 
Rock Pipit 3 - 1 on Red Nab and 2 on foreshore 

I checked the shore out from the saltmarsh again this evening (MD). As expected the inshore mud was dry and waderless. This is the mud where the Curlew Sandpiper etc were feeding yesterday.
The mud was dry and not a snail in sight today. There is a snail, relatively safe, under every pimple here.
High tide was only 7m. It didn't even cover the sandbars to the south of the recording area where most of the waterline waders were feeding. There were a few within our area.
Oystercatcher c200
Curlew c100
Whimbrel 1 heard only
Redshank 40 
Bar-Tailed Godwit 18
Grey Plover 4
Knot 24
Dunlin 30
Ringed Plover 6
Lapwing 12 on Red Nab

Mediterranean gull 7 adult seen on the shore, but the gulls were well spread and it is likely that there were more.

Just south of the recording area

10:55 - Osprey flew from inland, west over Mark Jones' caravan. It was mobbed by gulls as it reached the shore and veered off to the south, before being lost from sight.

Lots of small wader food = lots of small waders.......and some good ones too!

Very light east breeze. Overcast but very warm all day. There must have been lots of Saharan sand in the clouds, as a light shower covered everything in fine dust!

South shore (MD)
We have, very quickly, moved back to neap tides, so I walked to the waterline out from the saltmarsh late afternoon as the tide was coming in. On the way out, there were areas where the small sea snails were covering the mud. They are always present, but normally hide just below the mud surface when the tide is out.
This is about a square metre of mud. You can see the density of the snails.

These are the snails, if you look in the bottom left corner it appears greenish, this is the 
algae that I suspect the snails are feeding on.

This is one of the snails. The waders eat them whole, but they normally have to dig for them

This is another section of drier beach, the snails have all attempted to hide in the mud.......

........but the detail shows that some are barely hidden
I suspect that a combination of a quick change from spring to neap tides, leaving much of the mud wet, and the very warm weather allowing the algae to form quickly tempted the snails out to feed, they were only visible in numbers on the wettest sections of the shore.

Mediterranean Gull 7 adult
Shelduck 14
There were a lot of waders on the waterline and many more just resting on the shore, presumably well fed!
Oystercatcher c600
Curlew c200
Bar-Tailed Godwit 121
Grey Plover 22
Knot c300
Redshank 10 
Dunlin c1,000
The tide only comes in slowly on neap tides, but this is the moment, that the wake from the Seatruck reached the shore. You can hear it lapping about my feet and it moves the Godwit, Knot and Dunlin further up the shore.

As I was walking back I noticed a group of small waders feeding on a wet section of shore near the saltmarsh. Sure enough, as I got closer the density of snails was increasing. The group was quite flighty but roughly consisted of. 
Ringed Plover 35
Dunlin 25
Curlew Sandpiper at least 3 juvenile 
Sanderling 1 juvenile 

These are two of the Curlew Sandpiper


Juvenile Curlew Sandpipers

Three juvenile Curlew Sandpipers in this shot (white rumps)

This is the juvenile Sanderling, you can see it, the plovers and Dunlin picking up the snails.

Sanderling, Curlew Sandpiper, Dunlin and Ringed Plover

Unfortunately, it is unlikely that there will be a repeat performance in the same place tomorrow. Today's tide would not wet this area again and the mud here will likely be dry, but other areas should provide opportunities.

Osprey feeding again

The light east wind only held out till about 08:00, it then drifted south and continued to the west. Hot and sunny again.

First some updates from Rosemary and Peter Silvester:
Female Emperor Heysham Nature Reserve Monday

Middleton Nature Reserve yesterday 
Male Black Darter

Female Common Darter

Male Common Darter

Janet went to check the Middleton Black Darters this morning, but only one remained where there were four yesterday evening.

Black Darter

Male Common Darter

One of the influx of Small Whites

South Shore (MD)
I went along the wall mid morning, it was a little early for insect movement but the early east wind was already largely to the south. Even so a number of insects were seen coming in off (then later some heading out to the south).
These were seen along the wall and in the scrub near the lighthouse 
Small White 11
Red Admiral 3 in off, 2 out
Small Tortoiseshell 1
Large White 1
Darters sp, probably Common, coupled pair came in off 

Rock Pipit 3 on Red Nab
Wheatear 1 on inner harbour
Wheatear with dredger passing behind

Robin 5 - 3 on foreshore/Red Nab and 2 between lighthouse and waterfall 
Robin on one of the battered buffers - used when the dredgers are in operation near the harbour wall.

Osprey 1 - it was feeding off the end of No.1 outflow 10:30, just before low water. The gulls were harassing it, but clearly there were plenty of targets as it was still managing to dive.

The calm clear water would make it much easier than normal to spot the fish, it is normally Bass that feed here, they have formidable spikes on their dorsal fin (Mullet also have a spiked dorsal fin, but much smaller), so the Osprey will have to be careful how it grabs one. It seemed to have got closer this time.

Near miss

It wasn't obviously ringed, but this shot suggests possibly 

I was showing the bird to some interested visitors when it managed a successful dive, so I missed filming it. But I did get this clip of it flying off to the SE. You can see it is carrying the fish upside down, it does have a large dorsal fin so almost certainly a Bass.
Presumably there will be other Osprey fishing trips to witness here, but you have to drop lucky with the timing. From arrival to leaving with a fish today only took 10 minutes. Although I expect it will take a lot longer in less favourable conditions.

Pink-Footed geese - Pete advises that there are lots on the move, worth watching out for.

Just outside the recording area - Heysham Moss
Peter and Rosemary had a look yesterday 
One of many Black Darters. This one a mature male

This unfortunate Migrant Hawker was doing its best to free itself from
the spider's web but we didn't think it stood much of a chance.

I had a quick look today (MD)
I didn't go into the raised moss, it is quite overgrown this year and the going is tough. But the main reason was that I didn't need to, a 100m walk along the tractor track to the north of the raised moss located 
Migrant Hawker 2
Common Darter 10
Black Darter 10 - including 2 females, which were too flighty to photograph!
Immature male Black Darter

This is the tractor track between the wooded area and the raised moss. There are four or five 
pools that can easily be seen along its 100m length, and it's nice easy walking.

A good day for insects

Quite a fresh east wind. Hot and sunny all day

First, this shot by Kevin Eaves, of a Whimbrel on Red Nab yesterday.
Whimbrel 

Heysham skear - low water 10:20 (MD)
Great Crested Grebe 10 - including this juvenile fending for itself 
Red-breasted Merganser 3 female/immature feeding together.
Eider 22 including 5 males at various stages of breeding plumage. This clip,shows two of the males plus the feeding mergansers.
Little Egret 15
Oystercatcher c500
Curlew c100
Redshank 80
Turnstone 60
Knot 5
Ringed Plover 2 - none seen on inner skear, these came in off and rested on the middle skear
Dunlin 1

Several butterflies were coming in off, 5 Small White, 1 Small Tortoiseshell and 1 Red Admiral, so I went to check insect movement on the south side.

Red Nab (MD)
Mediterranean gull - just 2 adult seen.
Adult Mediterranean gull, top left, with Black-Headed gulls
Redshank 150
Dunlin 1
Ringed Plover 13 - they were feeding on the small cobbles, a terrain that they are perfectly camouflaged for. There are nine in this clip.


The tide was just reaching Red Nab when I arrived. The insects will still have been coming in off the sea, but no longer focused along the sea wall, as they are when the tide is out. Even so there had obviously been some significant movement. Along the track from Red Nab to the Nature Park there were:
Migrant Hawker 1
Small White 8
Red Admiral 4
Small Tortoiseshell 1
There wasn't many more in the park itself, just:
Migrant Hawker 1
Common Darter 3
Large White 2
Red Admiral 2
Small White 3
Speckled Wood 3
Treble-bar moth in the Nature Park

This Common Whitethroat was eating the blackberries, a Robin singing in the background.

Middleton Nature Reserve 
Janet checked in the morning, there were plenty of active dragonflies, but mainly Common Darters. Their activity ensuring future generations.


Common Darters

The only other dragonfly was a Migrant Hawker.

I went to check early afternoon to see if anything interesting had moved in.....it had (MD)
Black Darter 4 male and a probable female - the males were defending small territories amongst the shallow pools that you have to cross to get to the peninsula on the main pond. I only got a quick look at the female as she moved through (obviously not impressed!).
This is the area, plus the very edge of the main pond behind me in this shot


They were all quite mature, but some still with hints of yellow markings.



Male Black Darter - uncommon here

Other dragonflies - only the main pond checked:
Common Darter 10+
Brown Hawker 3
Migrant Hawker 4

It was very hot. But the "resident" Heron was presenting its wings to the full glare of the sun. I can't think that this is to cool it down. Its wings appear to have insects amongst the feathers, perhaps it is using ants to help rid it of parasites. 
Grey Heron covered in insects

Janet called back in passing in the evening. She quickly found the Black Darters. These shots are with her mobile phone, they are just to show that you do not need an expensive camera, especially with these very approachable dragonflies.

Hopefully they will still be in the same area tomorrow
