Priorslee Lake:  04:15 – 05:40 // 06:30 – 08:15

(139th visit of the year)

Species added to my 2019 bird log from here
91      Yellow Wagtail
A bird flew low W over the dam at 07:20 and for a moment looked as if it might return to perch on the dam. Sadly it didn’t – I have yet to photograph this species here. A late date for a migrant? None of the nearby fields look suitable as a nest site this year for it to be a local bird.

Other bird notes from today
- The pen Mute Swan remained on the nest throughout with no sign of the cygnets. Being brooded I expect – she would not remain there if the cygnets had perished.
- An early party of Canada Geese seemed unsure where they were going, arriving from the SE, circling and leaving to the NE. Later 12 birds arrived from the S and landed
- The Tufted Ducks were confusing once again. A pair ‘appeared’ (as ever) by 06:35 and were present thereafter. A second pair dropped in at 07:10, briefly
- Two new broods of Coots, both with four juveniles.
- 4 Swifts arrived at 04:40 with numbers building and usually c.20 present. For a short while c.06:45 there were >40 dashing about

Bird totals:

Birds noted flying over or flying near the lake:
- 17 Canada Geese (?bound)
- 2 (2♂) Mallard

- 10 Wood Pigeons
- 32 Jackdaws
- 13 Rooks

- 1 Yellow Wagtail

Hirundines etc. noted:
- >40 Swifts
- 4 Barn Swallows again
- 2 House Martins

Warblers noted (singing birds):
- 7 (5) Chiffchaffs
- 19 (17) Blackcaps
- 3 (3) Garden Warblers
- 1 (1) (Common) Whitethroat again
- 1 (1) Sedge Warblers again

The counts from the lake area:
- 2 + ? (1 brood) Mute Swans (see notes)
- 12 Canada Geese
- 10 (9♂) Mallard
- 4 (2) Tufted Ducks
- 1 Grey Heron
- 3 + 2 (1 brood) Great Crested Grebes again
- 1 Moorhen again
- 18 + 18 (7 broods) Coots

On the lamp poles pre-dawn:
- 1 Silver-ground Carpet (Xanthorhoe montanata) moth
- 1 Common stretch-spider (Tetragnatha extensa) again

Seen later
- 1 Common Green Capsid (bug) (Lygocoris pabulinus)
and two species of shrub that have been flowering for some days that I have now identified:
- Guelder Rose (Viburnum opulus)
- a dogwood, likely Red-osier Dogwood (Cornus sericea)

‘Gimme, gimme, ...”. Junior chases after his breakfast from the parent Great Crested Grebe.

Both parents look on proudly as junior attempts to deal with the morsel.

This is almost certainly a Common Green Capsid (bug) (Lygocoris pabulinus). There are similar species that require a hand lens to separate: this is by far the most abundant.

An abundant shrub around the lake is Guelder Rose (Viburnum opulus) that has these distinctive flower clusters. The shrub has many alternative names – dogberry; water elder; cramp bark; snowball tree; European cranberry bush ....

Another abundant shrub in flower at the moment is this dogwood (Cornus sp.). There are a number of species and there are many cultivars sold in garden centres. I think from looking at the visible stem and the tight arrangement of the star-like flowers that this is likely Red-osier Dogwood (Cornus sericea).
