Stithians Hide Closure

Unfortunately the Golden Lion Hide at Stithians Reservoir will be closed until further notice. This due to maintenance work to the boardwalk path being required as it is currently unsafe. Work is also planned to replace the leaking roof and guttering.
This hide is owned by South West Lakes Trust they have been informed of the issues. The hide is now padlocked and there is barrier tape across the access path. Cornwall Birds will work with SWLT to resolve the problem as quickly as possible. In the meantime please respect the ‘No Access’ signs.

Davidstow Harvesting – A response from Forestry England

Over the past few weeks we have recieved some emails from concerned members reagrding the continuing harvesting operation at Davidstow Woods and the potential threat to early nesting rare breeding birds.

After making some enquiries I had a very helpful email back from Reuben King; the Forester of the site:

Dear CBWPS,

Thank-you for your enquiry related to the harvesting works at Davidstow.

We have begun our planned harvesting and continue to monitor the site for nesting birds, If we find any we will put in place appropriate exclusion zones to minimise disturbance.

Considering a range of constraints, there is no risk free time of year to work, but we plan our work to minimise its impact. We have started the harvesting in Davidstow now to attempt to avoid the spring/summer period, whereas we recently worked Rough Tor Plantation during the summer months to minimise the impact on the important starling roosts.

The Bodmin Forest Plan (Bodmin Forest Plan) covers an area approx. 589ha which provides a range of habitats for different nesting birds. The area we are currently harvesting at Davidstow covers approx. 2% of the Bodmin Plan area. Our programmed cyclical felling and restocking continues to provide structural diversity to the forest, providing habitats for a range of wildlife.

With reference to Davidstow please ensure that your members comply with safety signage at all times.

If you have any further questions, please let me know.

Kind regards,

Reuben King

Forestry England

It is reassuring to hear that Forestry England are aware of rare breeding birds and will actively protect them. But we can help them with this by sending records to myself at [email protected]. I can then send the location to the forester who can set up an exclusion zone if it is needed. This is a great example of how sharing bird news with CBWPS can help sensitive species as we have excellent connections with orgisations such as Forestry England, Natural England and Cornwall Wildlife Trust.

Now is a great time of year to look for displaying Goshawk, drumming Lesser Spotted Woodpecker and calling Long-eared Owl at night. Sharing any sites you find with us will protect the breeding sites and help contribute to national surveys.

Dipper Survey – tetrads to be covered

Dipper – Alex McKechnie

To date 59 of the 92 Dipper Atlas tetrads have been allocated, spread between 26 volunteers. There’s plenty more if you include grey wag but if I could get all the Dipper tetrads covered that would be fantastic. If those of you that have not yet volunteered could please consider taking on one or two that would be very helpful. Maybe also forward to anyone you think might help.
Waiting to hear from some but at present gaps are:-
SW42 NEWLYN – M
SW42 PENZANCE – Y
SW53 HAYLE – B
SW62 HELSTON – U, V
SW84 TRURO – C,H,I,J,M

Port Quin Seaweed Farm



David Collins, our Ecology Officer has commented for Cornwall Birds on the MMO consultation, 23 Feb 2024 as follows:

I am writing to express my concern about the proposed Seaweed Farm in my role as Ecology Officer for Cornwall Birdwatching and Preservation Society. The Society is a registered charity with over 1,000 members.
Having considered the relevant environmental documents that were submitted with the application, I note that impacts on the Pentire Peninsula SSSI have been dismissed on the basis that both of the proposed seaweed farming areas are more than 500m from it. I assume this is on the basis that the relevant Impact Risk Zone for the SSSI is 500m. We do not support this assumption because the SSSI is important for breeding seabirds which will be feeding much further from the SSSI during the breeding season, including the areas proposed for this development.
The Pentire Peninsula SSSI is, amongst other things, designated for its breeding seabirds. The SSSI citation mentions Guillemot and Razorbill as species for which the site is important. We are aware that Mouls Island, which is the part of the SSSI closest to the proposed development, is of particular importance for both these species. It is also the only site in mainland Cornwall for small numbers of breeding Puffin. All three of these species will be travelling much further than 500m to find food for their young during the breeding season, and will be using the bay at this time as well as during other seasons. We would therefore expect the application to include consideration of the potential effects of the proposed development on these species. Should there be any negative effect on the feeding of auks as a result of the development, this would be detrimental to the status of the species within the SSSI.
Given the presence of the SSSI and the marine species it supports, we are surprised to note that there appears to have been no consultation with Natural England.
We are aware that there is limited information available on the effects of this type of development on seabirds in general. A recent paper (Corrigan, S; Brown, A.R.; Ashton, I.G.C.; Smale, D.A. and Tyler, C.R Quantifying habitat provisioning at macroalgal cultivation sites. Reviews in Aquaculture 2022; 14; 1671-1694) suggests that these sites may provide additional foraging for seabirds, but that they could be displaced due to construction and operation activities. Hence it concludes that the effects are uncertain – there simply isn’t enough information to know what the effects would be.
Due to the importance of this area for breeding auks, and the fact that the auk colonies are within an SSSI, we therefore request that the effects of the proposed development on these birds is properly considered before the planning application is assessed. Furthermore, we suggest that detailed consultation with relevant staff in Natural England is undertaken, as is required where a planning application has the potential to significantly affect species that are protected by that designation.

Keep an eye out for ringed Spoonbills

Over the autumn and winter we’ve received reports of several colour-ringed Spoonbills, giving a great insight into where these strange birds originate.

Green V463

This bird was ringed as a chick at Høje Sande, Ringkøbing Fjord in Denmark in June 2023 and turned up at Marazion Marsh on 28th September, before unexpectedly wandering back north to Potteric Carr, South Yorkshire, seen on 10th-15th October. Realising the error of its ways, it returned to Marazion Marsh four days later and commuted between there and Hayle estuary until at least 9th December.

Spoonbill and Little Egret, Martin Webb

Great White Egret and Spoonbill – Alex McKechnie

BW[AE]

This second bird has an equally interesting, but far more extensive, history. Ringed as a chick at Schiermonnikoog, Oosterkwelder in The Netherlands in July 2006, it spent its first winter 470 km away in France before returning to The Netherlands. It spent its second winter in Poole Harbour, Dorset, then again returned to The Netherlands. Subsequent winters were as follows:

  • 2008-09: Devon and then on the River Tamar in Cornwall in February 2009
  • 2009-10: Yealm estuary, Devon, then back on the River Tamar in January 2010
  • 2010-11: France in September/October, Dorset a week later and River Lynher, Cornwall in December 2010, then back to Devon in January
  • 2011-12: Poole Harbour, Dorset
  • 2012-13: Poole Harbour, Dorset
  • 2013-14: No sightings
  • 2014-15: Poole Harbour, Dorset
  • 2015-16: Poole Harbour, Dorset
  • 2016-17: Poole Harbour, Dorset
  • 2017-18: Poole Harbour, Dorset
  • 2018-19: Poole Harbour, Dorset
  • 2019-20: France in October, then Poole Harbour, Dorset
  • 2020-21: France in October, then Poole Harbour, Dorset
  • 2021-22: Poole Harbour, Dorset
  • 2022-23: Poole Harbour, Dorset
  • 2023-24: Poole Harbour, Dorset and Roiver Lynher, Cornwall on 16th January

So this bird is pretty faithful to a wintering area, but does wander a little and really does highlight the value of reading colour rings on birds.

Spoonbill – Rick Napp

Many thanks to the colour ring coordinators for their feedback on the reports and of course to the photographers who reported them. If you see any colour-ringed birds, the Bird News team can always help track them down so do let us know.

Gerrans Bay Planning Application


Cornwall Birds regularly monitor planning applications in the Duchy for potential impacts on birds and their conservation. Recently our attention has been drawn to an application to the MMO for two large seaweed farms in Gerrans Bay. This is an important wintering area for seabirds especially divers and grebes. It is unclear what impacts these farms may have on seabirds. Together with the RSPB, the Society will be commenting on the application registering our concerns as follows:-

  • Effects on foraging behaviours
  • Disturbance displacement (day and night/ feeding or roosting sites) though noise, light or presence of structures or people.
  • Bird strike due to entanglement or striking cables, etc.
  • Reduction in or changes in food availability due to changes in ecology/hydro morphology, etc.
  • Pollution incidents/disease/biosecurity issues.

The Cornwall Willow Tit Task Force – Training Day

Willow Tits, since 1970, have seen a population decline of 94% in Britain and have earned the unenviable title of Britain’s fastest declining resident bird. A collaborative project led by CBWPS and the University of Exeter has been launched, seeking to combine sound science and expert local knowledge to find practical solutions to bolster the species in Cornwall.

There’s a lot to do but we’re off to a flying start, with a pot of funding already secured for enhancing habitat at Goss Moor national nature reserve.

The Project

Headed up by CBWPS Vice-Chair, Pete Roseveare and University of Exeter PhD student, Daveron Smith we are working with partners in Cornwall to collaboratively co-design and deliver landscape-scale initiatives that benefit both Willow Tits and the people that live and work in the landscape. By:

  • Building relationships with local & national partners to better understand the species’ ecology
  • Co-designing interventions, underpinned by scientific evidence, that are mostly likely to help this species, accounting for real-world constraints & opportunities
  • Working in partnership with local land managers to drive changes in land management, leveraging nature recovery funding streams where available.
  • Co-developing a monitoring framework and platform to measure and share the success of interventions

Why Cornwall?

The natural environment in Cornwall is at the core of our identity and heritage, and the region is globally renowned for its beautiful land and seascapes and their unique history. However, its nature is highly fragile and not as healthy as it might seem. Nearly half of our breeding birds have declined, and several have already gone extinct. Work to help reverse these declines needs to begin now.

Why Willow Tits?

Our endemic subspecies of Willow Tit (Poecile montanus kleinschmidt) is Britain’s fastest declining resident bird, and within Cornwall is precipitously close to extinction. There is an urgent need to change the management of habitats, at landscape scale, to prevent this. With specific habitat requirements, a fragmented distribution and an aversion to dispersing over large expanses of open terrain, the species also presents an opportunity to consider more generally how landscape scale conservation can and should be carried-out. Such interventions are likely to bring about positive change for a range of other species and ecosystem services.

Willow Tit ‘Task Force’

We are well on our way to establishing a ‘Task Force’ of birders, land managers and conservation bodies to ensure Willow Tits, people and other species, see beneficial outcomes through this project. We have managed to leverage this so far to unlock funding for habitat works on Goss Moor which CBWPS will help to shape.

What next?

Habitat survey is ongoing – drawing upon RSPB methodology in Willow Tit habitat assessment we are also collating existing datasets and working with licenced bird ringers and other partners, to acquire insights into the ecology of the species locally and identify knowledge gaps.

Long-running survey effort, beginning this winter, will develop our understanding of the distribution of Willow Tits in Cornwall. CBWPS members are uniquely placed to help us with this effort and, over the coming months, we would be very interested in hearing from people that would be prepared to carry out some Willow Tit survey at locations throughout Cornwall, including well known strongholds and areas the species historically frequented.

What does this project offer for you?

For a birder, this group can:

  • Use your skills to inform a large-scale project that will benefit Willow Tits in your area
  • Give you the opportunity to work alongside researchers and conservation organisations to guide local conservation actions
  • Provide training and upskilling for our standardised Willow Tit Survey method
  • Provide targeted survey focus in the winter to early spring period

We will be hosting training on December the 2nd where we will delve into the methodology and recording in greater detail.

If you would be interested in coming along to the training and undertaking field surveys this winter, please contact Pete Roseveare and Daveron Smith using [email protected] or drop Pete a call using 07955216836 after 5pm and he will happily provide further information.

Northern Harrier on the Lizard Peninsular

You may have heard that a rare species of raptor has graced Cornwall since 28th September, a juvenile Northern Harrier! This sublime looking bird of prey has delighted many birders from across the country and has been a welcome addition to the county lists of most Cornish birders too. Here we discuss where it came from and what makes it identifiable from the more expected Hen Harrier.

Local birder Edward O’Connor reported an interesting looking harrier species from his local patch at Higher Bochyn; a Natural England Reserve located on Goonhilly Downs. A team effort ensued to confirm suspicions that it was indeed a juvenile Northern Harrier; a 2nd for Cornwall.

So what makes this bird a Northern Harrier, rather than our resident Hen Harrier? At a distance you may notice that it has a darker looking head and the extsensive orangey hue to the underparts is certainly very eye-catching, when compared to a typical juvenile Hen Harrier. The devil is in the detail with this particular species though and to confirm the identification you need close and clear views of some subtle features that are best expalined via these stunning photographs and text from Mashuq Ahmad; a member of our County Rarities Committee.

 

Primary 9 and Primary 8 with 6 bars (not including the dark tip. On P9, innermost bar faint and hard to see. Typically 4-5 on Hen (rarely 6) Also 4 bars on P10, (typically 3 on Hen).

Dark breast band and, diffuse streaking on the rufous-toned underparts, restricted to upper breast and upper flanks.

Darker, chocolate brown upperparts in general compared with Hen Harrier with obvious rufous, upper wing covert fringes (lower lesser coverts).

Dark facial crescent, solidly dark chocolate crown and dark chocolate neck boa. In combination, creating striking hood effect unlike Hen Harrier .

Only one previous record of Northern Harrier has been confirmed in Cornwall before, an adult male photographed at Men -an- Tol on 23rd November 2013. Why are they so rare? Amazingly they breed no closer to us than Canada and northern North America and only certain weather conditions can facilitate such an extreme occurence of vagrancy. As the Northern Harrier was migrating south along the East Coast of North America on its way to wintering grounds further south it will have got caught up in Hurricane Lee.  As the remainder of this powerful storm sped quickly across the Atlantic , an uprecedented arrival of American vagrants where found across Britain. The fast moving weather system, accompanied by a warm front was a key factor as birds managed to survive this incredible journey, a ‘perfect storm’ for rarities!

At time of writing (6th October 2023) the Northern Harrier is still being seen on the Lizard, currently around Kynance Cove. If you haven’t been down to see it then why not go and enjoy this stunning raptor in an idyllic setting.
