I will be concentrating on my aviation hobby for the next few days (weather permitting). Next report Monday?
Priorslee Balancing Lake: 05:20 – 06:30 // 07:25 – 09:45
(105th visit of the year)
Bird notes:
- a pair of Canada Geese flew in and were eventually chased away by the cob Mute Swan. Meanwhile another pair were on the football field c.06:15.
- the seven Greylag Geese goslings still doing well. Another adult pair visited, the parents chasing them away.
- two broods of Mallard ducklings: a brood of two several day old ducklings; another uncounted brood mainly hiding in the reeds.
- a Common Sandpiper present throughout.
- no gulls anywhere today.
- now at least 15 Swifts screaming overhead.
- a Skylark half-singing and half-calling over Castle Farm Way. Traffic noise prevented me from determining its direction. It is some weeks since I heard a Sky Lark without visiting Woodhouse Lane.
- a few changes in the warblers:
the same Sedge Warbler noted.
only five Reed Warblers heard.
no Lesser Whitethroats heard
the Common Whitethroat singing early only.
nothing that sounded anything like a Garden Warbler.
- a Mistle Thrush was seen flying out of the south-east copse across Castle Fame Way. Later two were seen in flight over Teece Drive. Probably two pairs nesting in the area.

The most exciting I could make the clear skies.
The Greylag Geese with their seven goslings.
The only fly-over goose today was this lone Greylag.
My friend the Grey Heron was watching me carefully from among the fast-growing reeds along the front of the dam.
One of two Speckled Wood butterflies Pararge aegeria I noted.
A Green Long-horn moth
Adela reaumurella. The wings are metallic-looking and only appear green with the light at the correct angle.
Tucking it to the last remaining flower on a spike of Cherry Laurel Prunus laurocerasus is a Tawny Mining Bee Andrena fulva.
This is a Chocolate Mining Bee Andrena scotica.
Here is another Red Mason Bee
Osmia bicornis . It lacks the hairs on the thorax of the somewhat similar Tawny Mining Bee. April is by far the month to see mining and mason bees.
Probably a Buttercup Cheilosia-type hoverfly: either
Cheilosia albitarsus or
C. ranunculi. Apart from one very distinctive species all the other
Cheilosia hoverfly species are essentially black and hard to identify.
A "first of the year" hoverfly for me was this Stripe-backed Fleckwing
Dasysyrphus albostriatus known to Obsidentify as Stripe-backed Brusheye. The down-sloping yellow marks combined with the two lines down the thorax identify this species.
Yet another Early Epistrophe
Epistrophe eligans, this a female. I do not record this species every year yet I must have seen double-figures today.
A well-posed male Tapered Dronefly Eristalis pertinax
Another "first of the year" species is this Tiger Hoverfly
Helophilus pendulus known to Obsidentify as a Tiger Marsh Fly and in some internet sites as a Sun Fly.
This is a Large Red Damselfly
Pyrrhosoma nymphula. Own up time: on 24 April I labelled a photo of this species as Red-eyed Damselfly
Erythromma naja by mistake. This latter species has a blue abdomen and red eyes. I also noted that it was my first April record of the species. That was not true either but it was my earliest-ever date for a Large Red Damselfly.
There were several of these dagger flies
Empis tessellata around today. I could not get a photo that included the "dagger" mouth-parts. The two stripes on the thorax and orange wing-bases separate this from other Empis dagger flies.
Forgive me: I am out of time and cannot delve in to the mysteries of fly identification. A number of well-marked examples I noted this morning follow. This is #1.
#2.
#3.
And #4.

Noted in the Priorslee Avenue tunnel:
Flies:
- 8 midges of several species
- *1 moth fly Psychodidae sp. [Drain Fly or Owl Fly]
I've not shown one of the c.100 species of moth flies
Psychodidae sp. for a while. I still can't find "real" moths here this year!

The Flash: 06:35 – 07:20
(104th visit of the year)
Bird notes:
Notable today was a Sedge Warbler singing again from the same spot as four of the other five records this year. It is in the sedges immediately behind the Long-tailed Tits nest which prevents any exploration. Often this species will sit out when singing but perhaps only when there are others nearby and it wishes to be seen. I saw the bird move but not well enough to tell the species. The song is distinctive so there is no question as to its identity.
Other bird notes:
- no Mallard ducklings seen.
- both Great Crested Grebes seen.
- *the Long-tailed Tits were still taking food to the nest so yesterday's Magpie did not return. At one point I noted three adults depart in quick succession.
Bird(s) noted flying over here:
None
Noted on / around the water:
- 17 Canada Geese
- no Greylag Geese
- 2 Mute Swans
- 23 (17♂) Mallard
- 9 (7♂) Tufted Duck
- 3 Moorhens
- 19 Coots again: also one well-grown juvenile
- 2 Great Crested Grebes
Warblers noted (the number in brackets refers to birds singing):
- 4 (4) Chiffchaffs
- 1 (1) Sedge Warbler
- 4 (3) Blackcaps
Noted around the area:
- *unidentified fly!
Traffic jam at the Long-tailed Tit nest. Two about to enter with breakfast...
...and a third waiting its turn.
And an unidentified fly here as well.
