21 Sep 15

Priorslee Lake: 05:46 – 09:05

Telford sunrise: 06:53

11.5°C. Cloudy with rain 06:20 – 06:50 and then again after 08:20. Light SSE wind. Moderate / good visibility.

(122nd visit of the year)

Everything affected by the rain

Other notes
- a few geese arrived early but soon left
- higher number of Tufted Duck this morning
- the large gulls mostly dropped in and then moved on after a few minutes, so rather few ‘pure’ over-flights
- 2 parties of Barn Swallows flew through in the rain after 08:30
- the Rook count was as normal this morning: in the rain the Jackdaws were mainly hedge-hopping below my sight-line as I took cover in the Sailing Club shelter and therefore under-recorded
- 6 Chiffchaffs (3 in song) were the only warblers located this morning
- House Sparrows again in hedge alongside the new academy
- 1 or 2 Pipistrelle-type bats: I was wondering whether echolocation worked in the rain and not sure I found out – I had two glimpses of bats flying but both appeared to be flying in a straight line and might have been different animals flying directly to roost rather than feeding. (The web suggests that both the inability to echolocate and the additional energy needed to keep warm when wet means that bats do not fly in the rain)
- a Flounced Rustic moth on the lamps
- 1 Silver Y moth in the Priorslee Avenue foot tunnel – a different specimen; also a lacewing sp. here

Counts of birds flying over the lake (in addition to those on / around lake)
For what it is worth in the misty conditions
- 2 Greylag Geese
- 19 Lesser Black-backed Gulls
- 6 Feral Pigeons
- 102 Jackdaws
- 136 Rooks
- 26 Pied Wagtails

Hirundines etc
- 24 Barn Swallows over

The counts from the lake area
- 2 Mute Swans
- 1 Greylag Goose (briefly)
- 23 Canada Geese (2 parties: both briefly)
- 27 (14♂) Mallard
- 36 (21♂) Tufted Ducks
- 2 Grey Herons
- 3 Little Grebes
- 8 + 9 Great Crested Grebes
- 7 + 11 Moorhens
- 203 Coots
- c.350 Black-headed Gulls
- 71 Lesser Black-backed Gulls
- 6 Herring Gulls

Another rather faded moth. However the dark marks in the middle of wing where they meet at rest is enough of a clue that this is a Flounced Rustic moth – a very common species and my 2nd of the year here.
