Priorslee Balancing Lake and The Flash

9.0°C > 15.0°C: A few early clouds cleared for a while with fair-weather clouds bubbling up later. Light mainly easterly breeze. Very good visibility.

Sunrise: 04:57 BST

* = a species photographed today
! = a new species for me here this year
!! = a new species for me in Shropshire

I have been unable to get as many photos organised as usual. I spent five hours this afternoon with a team from Severn-Trent helping them plan the woodland management to be done over-winter. I was invited as the "local expert" and was able to make sure they were aware of areas where specialist habitats needed to be preserved. All work will be done with ecologists on site.

Priorslee Balancing Lake: 05:00 – 06:05 // 07:05 – 09:35

(148th visit of the year)

Best today was the two Little Egrets that flew off East from the dam area at c.05:30.

Bird notes:
- a new brood of just two Mallard ducklings, too small to be any of those seen last week.
- no gulls on the football field c.06:00 and, strangely, no Wood Pigeons either. There are usually at least 20.
- one of the six Black-headed Gulls on the lake briefly was my first ginger-toned juvenile of the year.
- my first post-breeding sighting of a Kingfisher here
- after yesterday's big total of Rooks seen to the East I noted just seven today.
- a / the Cetti's Warbler sang just once in the south-west area at 05:45. Has he found and mate and is being kept busy feeding her and / or off-spring?
- a Common Whitethroat was heard giving quiet alarm notes at 05:40 suggesting that this unusually quiet bird might have another brood. That said it, or another, was heard singing near the Teece Drive gate c.09:00, a location I have not heard any previously this year.

The sunrise (more or less)

 Looking West as the first rays of the sun kiss the tops of the trees.

Almost flat calm early.

A Reed Warbler with food in its bill: one fewer damselfly.

The same Reed Warbler having eaten the damselfly. Time for a song.

Definitely singing time.

Reed Warblers have orange inside the mouth. The very, very similar Marsh Warbler has pink inside to the mouth. Luckily their songs are very different.

 Inspiration needed.

Butterflies remain scarce and there were none on the Butterfly-bush Buddleja davidii again but I did find my first Comma Polygonia c-album of the year.

With the light behind it and shining through its wings this is my first Mother of Pearl moth Patania ruralis of the year. The upper-wing does indeed look just like Mother of Pearl when it catches the light.

A Honey Bee Apis mellifera takes off with a full load of pollen.

Surprisingly my first Garden Bumblebee Bombus hortorum of the year proving that bumblebees can fly. Only a small amount of pollen in this one's pollen sac.

Meanwhile a Common Carder Bee Bombus pascuorum with a well-laden pollen sac. Bees are of course very important for pollination but other insect can be even more effective. Many bees remove much of the pollen rather than spread it around between flowers.

Staying well buried in vegetation was this ichneumon wasp. It is a male Ichneumon suspiciosus or one of several very similar species not separable from photos.

The white bands across the abdomen (at the edges of the tergites) help separate this Stripe-faced Dronefly Eristalis nemorum from other droneflies.

A very freshly emerged Common Blue Damselfly Enallagma cyathigerum. No markings as yet to enable the sex to be determined, just the stripes on the thorax. Behind it is an exuvia from which it probably emerged.

"I can see you". A 2 Spot Ladybird Adalia bipunctata hiding in the cracks on the boxing ring.

Meanwhile a 7 Spot Ladybird Coccinella 7-punctata sits in a White Clover Trifolium repens flower.

A White Crab Spider Misumena vatia waits for a victim.

Two moths this morning on street lamp poles: this is a Small Grey Eudonia mercurella

And this a Brimstone Moth Opisthograptis luteolata tucked up right at the very top of a pole. The lurking spider might be a Walnut Orb Weaver Nuctenea umbratica. Too far away to be certain.
