Priorslee Lake and The Flash

7.0°C > 8.0°C: Another day with much low cloud. Some spells of mainly light drizzle. Almost calm start with light NNE breeze developing. Moderate visibility: good later.

Sunrise: 06:16 GMT

* = a photo today

With earlier sunrise a reversion to "summer schedule" with a walk to and around The Flash between separate circuits of the lake

Priorslee Lake: 05:20 - 06:35 // 07:30 - 09:20

(38th visit of the year)

Two bird highlights this morning
- My fourth Little Egret record when one flew SSE high up at 06:15. I am sure the two Lesser Black-backed Gulls over at that time were no really accompanying it.
- A lone Sand Martin flew straight through at 08:45. I am elevating the 'hirundine sp.' record from the 4th March to this species on the basis of the views today's bird (and those seen at Trench yesterday)

Other birds notes:
- My highest count of Black-headed Gulls at the lake was 22, as logged. However there were 31 on the academy playing fields and these probably all visited the lake at some time.
- I was in position to see the Jackdaws (and any Rooks) on their way out of roost - typically around 05:50 at the moment. I heard and saw nothing until a lone bird at 06:10 that seemed unsure where to go.
- Just the two singing Chiffchaffs noted. One of these was still practising - more 'chiff-chiff-chiff-chiff-chaff'
- Many Siskins flying over / around.

Birds noted flying over / near here:
- 10 Canada Geese: two pairs outbound; quintet and single inbound
- 4 Greylag Geese: single outbound; trio inbound
- 4 Wood Pigeons only
- 6 Lesser Black-backed Gulls: all adults
- 1 Little Egret
- 1 Jackdaw only: see notes
- 1 Sand Martin

Counts from the water:
- 2 Canada Geese: arrived and departed much later
- 2 Mute Swans
- 5 (4♂) Mallard
- 19 (11♂) Tufted Duck
- 5 Moorhens
- 34 Coots
- 1 Little Grebe heard only
- 5 Great Crested Grebes once more
- 22 Black-headed Gulls: see notes
- 3 Lesser Black-backed Gulls: all adults
- 1 Grey Heron: departed

Strangely despite the mild and cloudy night there was nothing on the lamp-poles pre-dawn

Of note:
I met someone doing a census of Willow/Marsh Tit habitats (sadly long-gone from here). He happened to also be a botanist and he was able to point me to a new plant for my Priorslee list:
- Cornelian Cherry (Cornus mas) - a Spring-flowering shrub whose yellow flowers open along stems yet to acquire leaves.

The general rule is flowers before leaves = Blackthorn (Prunus spinosa); leaves before flowers = Hawthorn (Crataegus monogyna). This one breaks the rule - a Blackthorn with flowers and leaves together.

This is a flower of the Cornelian Cherry (Cornus mas). Not sure how I overlooked this bush in previous year - perhaps I ignored it because I did not know what it was!

The Flash: 06:40 - 07:25

(26th visit of the year)

Bird notes:
- Two eggs noted in the Mute Swan's nest
- Two Chiffchaffs chasing around at the tops of trees near The Priorslee. I could not tell whether both were singing or not. One singing from the island - a different bird?
- A lone Siskin in Alders along the E side
- A Reed Bunting heard calling along the E side. Could not locate it.

Birds noted flying over / near The Flash:
- 3 Canada Geese

Counts from the water:
- 35 Canada Geese
- 1 Greylag Goose
- 3 Mute Swans
- 30 (18♂) Mallard
- 69 (42♂) Tufted Duck
- 8 Moorhens
- 24 Coots
- 1 Great Crested Grebe
- 1 Black-headed Gull: departed
- 1 Herring Gull: the usual second year, arrived

Two Mute Swan eggs this morning. Perhaps the left-hand one is partially obscured by vegetation: it looks smaller.

Between Priorslee Lake and The Flash

- Moorhen(s) heard from the upper pool and one seen in the Wesley Brook where it enters the pool - and area now cleared of vegetation cover.
- A Grey Wagtail in the Wesley Brook where it passes underneath Priorslee Avenue.
- Long-tailed Tits and Goldcrest around the lower pool
