Priorslee Lake: 04:45 – 06:30 // 07:35 – 09:30
(181st visit of the year)
Bird notes:
- The weather was too dull to count all the Great Crested Grebes from any one location and they were too mobile to obtain a meaningful total from different locations.
- Two individual House Martins flew N at 06:05. Today I saw them: other days recently at similar times I have only heard them. I wonder whether they are local birds returning from a roost site. It seems to me that if pairs have several broods then they cannot all roost inside the nest. So where do they go?
- Soon afterwards a noisy party of 22 Barn Swallows appeared overhead. If I had any doubts about whether the last few days' sighting were migrants then clearly these were. I guess they were setting off from a nearby roost site. I have seen them overnighting in maize fields while on passage.
- At the same time I could hear what sounded like a large group of House Martins overhead but I could not locate them. None was seen or heard later.
- It is two weeks since I saw or heard any Song Thrushes. There were as many as nine singing males in the area. Most days during the breeding season I noted several non-singing birds gathering food. The recent dry weather will have made it very difficult for this species (and Blackbirds) to access food and they may well have moved on.

With clear skies to the East and low cloud overhead I was not expecting a decent sunrise.
However some colour did appear.
And got better.
Exceeding expectations.
The cob Mute Swan helps the sailing club removing some of the weed from the lake.
Meanwhile this one seems to have gone to sleep in its food – Common Knapweed (Centaurea nigra).
And these are from Elder (Sambucus nigra) still in various stages of ripening. These fruits are an important food for warblers fattening up for their migration.

The drake Gadwall (foreground) with the two ducks, identifiable by the orange edges to their bills.
The drake in his breeding finery. The ducks paddled away.
I do not recall having previously captured a Coot in flight
Flying Cormorants look almost pre-historic. Note the long tail which...
...is nearly in focus as it arrives!
One of the Grey Herons was having a bad hair day.
"Are you talking about me?"
It did eventually fly off.
And the underside (it had already been broken off). I did not try it to see whether it tasted peppery.

In the Priorslee Avenue tunnel:
One wall has been daubed with graffiti. I am sure someone thinks it fun and/or artistic rather than vandalism.
Moths:
- 1 Large Yellow Underwing (Noctua pronuba)
and
- 2 White-legged Snake Millipedes (Tachypodoiulus niger)
- 1 Common Rough Woodlouse (Porcellio scaber) again
