2020: The year at Priorslee Lake

Introduction

Since completion of these tables below, a very small number (five) of duplications have come to light. Please accept my apologies for these. The tables will not be changed here but note:
- the number of bird species I logged at the lake in 2020 was 108, one fewer than 2019 (my highest).
- the number of moth species I logged at the lake in 2020 was 104: my highest.
- the number of bird species I logged at The Flash in 2020 was 76.

LOOKING FORWARD

In 2021 I will be adopting the latest systematic order as published by the BTO (British Trust for Ornithology) in line with latest scientific evidence - mainly recent DNA analysis.

This will all be very confusing as I have barely got used to the previous revision and struggle to think of the order not starting with divers and grebes; and crows near the end with only buntings to follow. There are some dramatic changes and some tinkering.

Major changes include promotion of all game birds (Pheasants and their allies) to the front. Swift is ahead of demoted grebes and followed by cuckoo and pigeons and doves. These are before waders which are now ahead of demoted birds of prey.

Tinkering occurs at several levels. Geese come before swans. Terns have been placed after gulls - where they were 'in my day'. But it is not that simple as within gulls the Great Black-backed Gull now precedes Common, Lesser Black-backed and Herring Gulls rather than being the last of the group.

Also some warbler families have been swapped with 'reed' warblers (Sedge, Marsh, Reed) now preceding 'scrub' warblers (Blackcap, Garden Warbler, and whitethroats).

Other tinkering has Canada Geese promoted over Greylag Geese. Also Willow Warblers are now ahead of Chiffchaffs - again where they used to be.

Will take us a while to get used to this change.

REVIEW OF 2020.

It started rather quiet with nothing unusual in the way of geese, ducks and gulls. There was a Pink-footed Goose at Trench but it never made it here.

Just as a few species were about to move I was away in the USA for ostensibly just over two weeks in mid-March. Covid had other ideas and I returned early only to miss out on much of the Spring passage due to the lockdown

Clarification of lockdown rules allowed me to drive the short distance from Newport for my daily exercise and resume watching. Social Distancing was not hard at 05:30.

Late Spring and early Summer produced a few late passage birds - Oystercatcher, Ringed Plover and Wheatear. Warblers had set up territories and I was able to get some good photos of birds carrying food and then of barely fledged juveniles. A Yellow Wagtail breeding in the fields to the east was a first for me in the area. No sign of Linnets nest around the lake this year.

Mid-Summer visitors are unusual: I was concentrating on moths around the street lights when a Barn Owl put in an unexpected appearance for just one morning.

Autumn passage allowed me to catch up on a few species missed in Spring - Curlew; Spotted Flycatcher.

Late Autumn produced the usual large parties of Wood Pigeons - I estimated over 9000 on the busiest morning. Winter thrushes - Fieldfare and Redwing - were in low numbers, unlike the East Coast that recorded record numbers. A typically noisy Cetti's Warbler sang for a few days. I missed out on the reportedly brief visit by a Shag while I busy photographing juvenile Bullfinches.

A roost of, mainly, Lesser Black-backed Gulls on roofs in Hortonwood led to an early morning arrival by these for a drink and a bathe before setting off on the day's activity. As usual gulls attract gulls and we were treated to fairly regular visits by some uncommon species that can be a challenge to identify - Yellow-legged and Caspian Gulls. A few Great Black-backed Gulls were noted as well.

Possibly the bird of the year was a drake Red-crested Pochard for a few days at the end of November. My first here for 19 years and looking rather too exotic for England.

In the end I managed a tie with last year in the number of bird species personally recorded - 109.

MOTHS

I made a concerted effort to start early-enough to see as many moths as possible attracted to the street lights along the West end footpath. I was well rewarded with a bumper number of species with many new for me at this site and several that I had never seen before. There is plenty of scope for additions. A portable moth trap would boost the number of common species recorded as well as attract a few more specialities. Time, time ...

Moth species new in 2020

Plain Gold Micropterix calthella
Horse-chestnut Leaf-miner Cameraria ohridella
Willow Ermine Yponomeuta rorrella
Orange Crest Helcystogramma rufescens
Nut-bud Moth Epinotia tenerana
Treble Brown Spot moth Idaea trigeminata
Blue-bordered Carpet Plemyria rubiginata
Small Seraphim Pterapherapteryx sexalata
Vapourer Orgyia antiqua
Buff Footman Eilema depressa
Small Ranunuculus Hecatera dysodea
Pale Pinion Lithophane socia
Blackneck Lygephila pastinum

Micro moths do not have universally accepted common names. I have adopted those used by the excellent Norfolk Moths web site. I use the 'flying tonight' tab to narrow my search for species I am unfamiliar with.

HOVERFLIES

Another group that I have tried to get to grips with (ably assisted my friend Leon Truscot in Saltash, Cornwall). I have yet to get to grips with the systematic order - I am not sure where one of available on the web. I record them in scientific name order as not all species have accepted (or indeed any) vernacular name. Not all species can be positively identified by even good photos and not all my photos were that good!

BEES

I acquired the latest Bees of Great Britain and Ireland Field Guide rather too late in the season. I then made an effort to get to grips with this group.

In scientific name order:
This must be regarded as a very provisional with a few tentative identifications!

Honey Bee Apis mellifera
Gypsy Cuckoo Bee Bombus bohemicus
Field Cuckoo Bumblebee Bombus campestris
Garden Bumblebee Bombus hortorum
Tree Bumblebee Bombus hypnorum
Red-tailed Bumblebee Bombus lapidarius
Common Carder Bee Bombus pascuorum
Early Bumblebee Bombus pratorum
Buff-tailed Bumblebee Bombus terrestris
Vestal Cuckoo-Bee Bombus vestalis
Red Mason Bee Osmia bicornis

THE FLASH

I spend less time at The Flash than at the lake. This combined with the smaller size of the water and the built-up surroundings necessarily leads to a smaller species list. The island, sadly getting smaller annually, provides a refuge that some species, like the geese and Goosanders utilise.

Highlights this year have included

- A late Christmas present of my first Little Egret for two years.
- My first-ever Red Kite at this location: a fly-over on 16th October.
- A Reed Warbler set up territory alongside Derwent Drive and sang for several weeks. I don't think he attracted a mate. I noted passage birds on 11th May 2015, 28th May 2017 and 24th May 2018 but it is over 6 years since the last breeding attempt in reeds now flattened to create a fishing peg.
- A Reed Bunting also held territory near the top end. I saw a male carrying food so nesting was attempted. No juveniles were seen. In some previous year I have heard birds in early Spring but none has stayed.

BIRDS

Species seen in 2019 but not 2020

Goldeneye
(Common) Kestrel
Oystercatcher
Curlew
Snipe
Common Tern
Yellow-legged Gull
Ring-necked Parakeet
Sedge Warbler
Common Crossbill

Apart from the briefly resident Ring-necked Parakeet all of these were one-off sighting of passing birds. Apart from perhaps the Common Tern I would not expect to see any of these annually.

MOTHS

Mothing at The Flash is quite different from the lake as all sighting are made well after dawn when many individuals will have flown off to hide. So many fewer species are to be expected
