Seven Hours at Linacre!

 Yesterday (19th), I had a couple of visits to Linacre. The first, from 06.00 - 09.30, was a ringing session, with 3 other members of Sorby Breck Ringing Group, whilst the second from 14.00 - 17.30, was a solo walk, looking for insects and carrying out this month's WeBS walk.

The ringing session was quite a quiet affair, with just 9 birds ringed. Happily, 8 of the 9 birds were juveniles, i.e. born this year, but the low number was quite disappointing, given the time of year. Hopefully, numbers will pick up, as the summer progresses. Bird caught were (new/retrap): Blackcap 1/0 (juvenile), Chiffchaff 4/0 (all juveniles), Robin 1/0 (juvenile), Blue Tit 1/0 (juvenile) and Bullfinch 2/0 (1 adult - born last year, and 1 juvenile).

By the afternoon, the temperature had risen to 22 degrees, so I went back down for a walk around the site. As you can see from the picture below, the bottom reservoir is currently nearly dry. It has been drained as maintenance work is being carried out on the overflow. As a result there were few birds there, but the exposed mud could bring in some waders perhaps.

Bottom reservoir

Waterbirds see were: Mallard (42 - 40 adults and 2 juveniles), Tufted Duck (24 - all adults), Mandarin Duck (17 - all adults), Coot (1 adult), Moorhen (3 adults), Grey Heron (1), Great-crested Grebe (3 adults - no juveniles this year), Herring Gull (1 adult), Lesser Black-backed Gull (5 adults and 1 juvenile),and, the best of all, a juvenile Common Sandpiper!

Whilst on site, I also spent a lot of time (!) looking at the amazing number of butterflies and other insects present. Very conservative estimates of species seen are: Meadow Brown (50+), Gatekeeper (9), Speckled Wood (3), Comma (2), Painted Lady (6 - 5 very fresh looking individuals and 1 very tatty one!), Holly Blue (4), Green-veined White (2), Large White (1), Peacock (3), Small Skipper (1), Silver Y (1), Shaded Broad-bar (1 in the ringing site), Brown Hawker (2), Common Blue Damselfly (100+, including ovipositing pairs), Blue-tailed Damselfly (1 male), Migrant Hawker (6), Volucella inanis (2), Volucella pullecens (3), Myathropa florea (1) and Eristalis sp!

Another new species for Linacre!

 I've had a couple of 2-hour visits to Linacre this week and managed to record lots of insects, including a new species!

The first walk, on 28th, with 3 of the volunteer rangers, resulted in the new species, a queen Median Wasp, that was seen, basking on the bracken next to the middle reservoir.

 Based on the year so far, this afternoon's walk around Linacre, was by far the best one for insects this summer. In total, I saw 7 different species of butterfly, along with 3 dragonfly species, 4 hoverfly species and a few other insects. In addition, I go my first Linacre Hobby since 2013!!

The butterflies seen were: Peacock (9), Red Admiral (5), Speckled Wood (5), Large White (1), Small White (4), Comma (2) and Meadow Brown (2).

Birdwise, it was quite quiet, but the obvious highlight was a Hobby that was chasing a couple of Swallows! My last Linacre record of this species was way back in September 2013!! Other birds seen were: Canada Goose (20 on the top reservoir), Great-crested Grebe (4; 2 adults and 2 juveniles), Little Grebe (1), Swallow ( 4 in total), wheeting Chiffchaffs, Grey Heron (1), Tufted Duck,  Mallard and Mandarin Duck.

Linacre Insects - 3 new species!

 The summer of 2024 has, so far, been pretty awful weather wise, with very few periods of dry, warm weather. Today, the temperature managed to drag itself to 17 degrees (!), and there were a few sunny spells, so Jayne and I had a couple of hours at Linacre, and managed to find 3 new species!!!!

Although it was sunny, the number of insects seen was still pretty low, but it did, at least, have a few new records for the year, along with the new ones. Firstly, we spotted Common Blue Damselflies (c15), followed by 1 Speckled Wood, Swollen-thighed Beetles, Red and Black Froghopper, 3 Green-veined White, 1 Volucella pellucens (Great Pied Hoverfly), Eristalis sp, 1 Myathropa florea, 1 male Sericomyia silentis, 1 Mayfly sp, 3 Cinnabar Moths, 1 Latticed Heath and White-tailed and Common Carder Bumblebees.

 This morning I had three hours walking around Linacre, checking the nestboxes, carrying out this month's WeBS count, and looking at the insects that were out and about in the 20 degree temperature. 

First up the nestboxes. I walked around and checked the last few remaining nests, and the great news is that they had all fledged successfully, including the three Pied Flycatchers- hurrah!! I'll write another blog post about the totals later in the year.

Next, the WeBS walk. Species (and numbers seen) were: Mallard (99; 83 adults and 16 ducklings), Tufted Duck (41 adults), Mandarin Duck (42; 32 adults and 10 ducklings), Coot (22; 12 adults and 10 juveniles), Moorhen (20; 11 adults and 9 juveniles), Great-crested Grebe (8; 5 adults and 3 juveniles), Little Grebe (2;1 heard on the middle reservoir and 1 seen on the top reservoir), Grey Heron (1), Grey Wagtail (1), Lesser Black-backed Gull (1 adult), and, best of all, a Common Sandpiper on the bottom reservoir - the first record of the year!). Other birds seen or heard were: Song Thrush (2 heard), Chiffchaff (3 heard), Blackcap (4 heard) and Garden Warbler (1 heard in the ringing site). 

Insects were the best I've had so far this year, with several first sightings. Meadow Brown (15 - an excellent count across the site, and the first Linacre record of the year), Ringlet (2 in the ringing site - first Linacre record of 2023), Speckled Wood (5), Red-tailed and Tree Bumblebees, Red and Black Froghopper, Common Blue and Azure Damselflies (the latter species, the first Linacre record of 2023), Swollen-thighed Flower Beetle, Volucella bombylans (white-tailed variety), Volucella pellucens (first 2023 record), Latticed Heath (2) and a Harlequin Ladybird larvae.

Volucella zonaria at Linacre - 17th August 2021

 I had my forst visit to Linacre since betting back from Cornwall, on Tuesday. It was a very grey, overcast day, with a maximum of 16 degrees and frequent drizzly rain! Thankfully, there were a few breaks in the  cloud, which allowed me to see a few insects, including  a new species for me at Linacre - Volucella zonaria!

Volucella zonaria is a species of hoverfly that has been extending its range in Britain over the last few years. I've recorded it in Derbyshire before (at Hardwick Hall), but Tuesday's sighting was my first at Linacre. 2 individuals were seen, along with two other Volucella species; Volucella inanis and Volucella pellucens (no photo).

White-letter and Purple Hairstreaks!!

It was 22 degrees again today, so Jayne ad I had a walk around Linacre this afternoon. The top reservoir was closed off as the boardwalk is being repaired, so we just walked around the bottom and the middle reservoirs.

At first it was overcast, but then the sun came out, and we managed to record some insects, including the butterflies in the title! Both these species were seen at about 3pm on the pathway leading down from the toilet block to the bottom reservoir. There were at least two White-letter Hairstreaks - a lifer for me, and one Purple Hairstreak.

There were also 15 Lesser Black-backed Gulls on the middle reservoir (13 adults, 1 juvenile - this year's bird, and 1 immature bird) and a juvenile Black-headed Gull.

The last sighting of note was a rodent - a Bank Vole I think, that was seen coming out of a hole under an oak tree by the main path - my first sighting here.

Bank Vole?

Hardwick Ponds - 24th July 2021

 Jayne and I had a walk around the ponds at Hardwick Hall yesterday. It was 20 degrees, with a lot of cloud cover and a few sunny spells.

Whilst there we saw 6 species of odanata, the highlight being my first record of Small Red-eyed Damselfly for this site. Other species seen were: Red-eyed Damselfly, Common Blue Damselfly, Emperor, Brown Hawker and Black-tailed Skimmer.

Linacre Ringing - 18th July 2021

Last Sunday I was down at Linacre for a mist netting session with Sorby Breck Ringing Group. It was our first session since May, and we managed to catch  a good number of birds, including our first juvenile warblers of the year.

Totals were (new/retraps): Blue Tit 0/1, Goldcrest 1/0, Great Tit 7/0 - all juveniles, Willow Warbler 2/0 - both juveniles, Chiffchaff 2/0 - both juveniles, Blackcap 6/0 - 5 juveniles, Blackbird 2/1 - 2 juveniles and an adult female, first ringed in 2019, Dunnock 1/0 - 1 juvenile and Wren 1/0 - juvenile.

The temperature was 20 degrees whilst we were there, so there were lots of insects about, including 2 Gatekeepers, 1 Brown Hawker, 2 Small Skippers, 2 Meadow Browns, 20+ Ringlets, 2 Great Pied Hoverflies and, nest of all, a single Purple Hairstreak!!!

Linacre - 12th August 2020

 The temperature was a cracking 27 degrees again today, so I decided to have a couple of hours down at Linacre to see which insects I could see. I started off in the ringing site and saw 4 Gatekeepers, 1 Comma, 2 Peacock, 2 Small Coppers, 1 Red Admiral, 2 Silver Y moths, and 3 Shaded Broad Bars.

Walking around the reservoirs, I added Common Blue Damselflies (including pairs ovipositing), 4 Brown Hawkers (my first Linacre record of 2020), a couple of male Blue-tailed Damselflies, and, very nicely, a male Banded Demoiselle flying over the top reservoir (my first Linacre record since 2015, and only my second ever record here). Another hawker, possibly Southern, was seen hunting along one of the paths by the middle reservoir. 

There were plenty of hoverflies around the site, including 1 Volucella pellucens a.k.a. Great Pied Hoverfly, and a single Myathropa florea a.k.a. "Batman hoverfly".

Myathropa florea

Birdwise, it was quite quiet, as is to expected, but I did have 2 Black-headed Gulls on the bottom reservoir (a very unusual August record), 11 Great-crested Grebes (2 family parties with 4 and 3 chicks, and 4 adults) and 2 Kingfishers on the bottom reservoir.

Linacre - 22nd July 2020

I had a couple of hours at Linacre this afternoon. When I arrived at 12.30pm it was grey, overcast and just 17 degrees. I started down at the bottom reservoir where I was very lucky to see a Kingfisher fly up from the river, over the wall and along the water. Also on the water were 20+ Mallards and a breeding plumaged Black-headed Gull. This gull was a very unexpected sighting, as the first ones don't usually return until September or October! One adult Lesser Black-backed Gull was also present on the top reservoir.

Black-headed Gull

About half way round, the sun came out, and so did the insects! 8 species of butterfly were seen: Large White (1), Small White (2), Green-veined White (1), Ringlet (2), Meadow Brown (c.10), Gatekeeper (2), Comma (2) and Peacock (1). A new species of day-flying moth, 6-spot Burnet Moth (3), was also seen, as were 2 species of damselfly: Common Blue Damselfly (c.3 pairs in cop and ovipositing) and Blue-tailed Damselfly (1 male and 1 female of the "rufescens" form).

LINACRE LIFER!!!

It was about 20 degrees on Thursday, so I popped down to Linacre in the afternoon for 3 hours to see what was about. In the sun there were lots of butterflies in and around the buddleia in the ringing site, including: Painted Lady (8 - it's been a fantastic year nationwide for this species, and my best ever at Linacre too), Red Admiral (1), Peacock (2), Comma (1), Wall Brown (1), Gatekeeper (1), Common Blue Butterfly (3 males, 1 in the ringing site and 2 on the bank below the top reservoir. A female was also seen in the ringing site on 23rd), Small Tortoiseshell (1), Meadow Brown (1), Speckled Wood (1), Small Copper (1 on the bank below the bottom reservoir) and Large White (2). Other insects seen were: Brown Hawker (2), Volucella inanis (1), Volucella pellucens (1) and many Marmalade and Eristalis hoverflies.

Birdwise it was relatively quiet, except for the Linacre lifer in the shape of a juvenile REDSTART!!

Redstart

This bird was seen flycatching on the boardwalk, with about 3 Chiffchaffs, for about 1 minute, during a short rain shower. Luckily I managed to get this photo before it flitted off into the bushes and disappeared. I only have one other record of this species at Linacre, 2 birds reported in May 2016, so it could be a breeding species, which has been missed, or it could  just be a passage migrant. Only time, and more records will tell. 

Other birds seen were: Mallard (71), Tufted Duck (14), Mandarin Duck (29), Coot (2 adults and no juveniles!!), Moorhen (12; 4 adults and 8 juveniles), Great-crested Grebe (1 adult), Grey Wagtail (1 juvenile), Robin (1 juvenile), Swallow (2), House Martin (6) and Lesser Black-backed Gull (10 dropped in for 5 minutes during the rain).

Linacre Insects - 6th August 2019

Yesterday morning I went down to Linacre to do the final check of the nestboxes (more of that in another post), and afterwards spent another 3 hours walking around the site recording the insects (and a few birds!).

It was pretty sunny all the time I was there (up to 22 degrees by the time I left), and there were a good number of insects to see. First up the dragonflies and damselflies. The most numerous species, as always, was Common Blue Damselfly, with 20+ seen, including 2 mating pairs. Two male Blue-tailed Damselflies were also seen, along with 3 Southern Hawkers and 5 Brown Hawkers.

Linacre Insects - June 2018

This is my first post of 2018 about the insect life that can be found at Linacre. I had a visit on 1st June when it was a lovely sunny day. I spent some time walking around the ringing site and then walked up to the top reservoir.

During the visit I recorded 3 species of damselfly: Blue-tailed, Common Blue and Large Red. The first 2 species are common around all 3 reservoirs, whilst I only saw 2 Large Reds, 1 by the boardwalk around the top reservoir and 1 in the ringing area.

Large Red Damselfly

I also saw 2 species of Volucella hoverfly, Volucella pellucens and Volucella bombylans, along with 3 other species of hoverfly: Episyrphus balteatus a.k.a. Marmalade Hoverfly, Eristalis nemorum (a dronefly sp), Helophilus pendulus and Myathropa florea.

Volucella pellucens

Volucella bombylans 

Butterflies seen were Common Blue (3 males in the ringing area), and a single Peacock (1 in the ringing area). Moths seen here were Cinnabar Moth (1) and Silver Y (1).

I was down again on Saturday (16th). The weather wasn't so good, so the number of insects was smaller. New species included Red and Black Froghopper, Straw Dot (moth), Yellow Shell (moth) and Black Snipefly.
