RSPB have kindly agreed to let us re-post their blog entry of recent sightings here at Lake Vyrnwy. If you would like to keep up to date with their recent sightings then take a look at their blog.
Top sighting this week was a flyover Yellow Wagtail from the Red Trail (23rd), this summer migrant usually inhabits lowland agricultural fields with the nearest known local population located towards Welshpool. Another highlight this week was an Osprey which flew down the lake (23rd). The lake also played host to 30x Canada Geese, 30+ Mallard, 3x Teal, 3x Great Crested Grebe, 1x Cormorant and 4x Grey Heron.
Frequent Kingfisher sightings this week included birds seen from the Lakeside Hide, below the dam and along the Afon Vyrnwy (Many Thanks to Gavin Chambers for this image taken at Vyrnwy last year).
Other interesting bird sightings this week included, Red Kite (regular along the Dinas Mawddwy road), Sparrowhawk (regular at the Visitor Centre), Green Woodpecker (1x juvenile, Green Trail, 1x Abertridwr), Dipper (regular, Afon Vyrnwy), Wheatear (Bala Road), Stonechat(Rhiwargor waterfall), Spotted Flycatcher (family parties, LLanwddyn and Dinas Mawddwy road) and Crossbill (Visitor Centre, Red and Green trails).
Siskin are regulars at the bird feeders at present (Many Thanks to Sam Constable for the image).
The distinctive blooms of Harebell can be seen along the Green Trail at present.
Purple Hairstreak butterfly should be searched for in the oak woodland at present with at least four sighted along the Green Trail this week (Many Thanks to Gavin Chambers for the image taken off site).
The weekly butterfly transect highlighted a fresh emergence of Peacock’s, with twenty individuals counted alongside a single Comma and small numbers of Ringlet, Large White,Green-veined White, Small Tortoiseshell, Meadow Brown and Large Skipper.
The blooms of Common Knapweed are providing a rich source of nectar for insects at present like this Skipper butterfly.
Odonata on the wing this week included, Banded Demoiselle (first record this year), Emerald Damselfly, Black Darter, Common Hawker, Brown Hawker and Golden-ringed Dragonfly.
Look how dark this male Black Darter is in comparison to last weeks female.
Macrolepidoptera Of The Week
This week’s top moth was also the focus of attention in the following mystery photo unveiled on the RSPB Mid Wales Facebook Page earlier in the week.
I can now reveal that the giant moth in the photo is a Northern Eggar. Well done to everyone who guessed correctly. Eggar moths are an important part of the Vyrnwy food web with the hairy caterpillars being a favourite meal for Cuckoo and the flying adults a food source for acrobatic Hobby’s. Dayflying ginger male Eggar moths may be seen zigzagging across the higher level trails at present.
Female Eggar moths were attracted to the light on our moth trap.
