Ringing Project data updates

Other than the groups general survey work, the ongoing ringing project continues to deliver good data. This season, whilst lockdown may have prevented much of the work SWP would hope to have carried out in any normal year, there are still interesting observations that get uncovered.

One of our regular monitored sites, in Devon has had the same breeding Falcon since 2014, she was herself ringed at Cann Quarry (Plymouth) back in 2011 (Darvic BX Black on Yellow), she has bred successfully in all but one season , when the site was particularly prone to an amount of disturbance. This year, four eyassess were raised to fledging. In one of the first post lockdown visits, it was great to reconfirm the same breeding female; but there had been a change in the male, as he too was carrying a Darvic ring. This has since been captured, thanks to a local Raptor conservationist John Deakins, who has given permission to use the image that clearly shows the Male with Darvic JN (Black on Yellow)

Moorland and Coastal sites are not always as easy to confirm ring ID’s as some of the Urban sites that have cameras monitoring the birds every movement. So it’s always good to get this information back, to feed into the growing data held and shared with the governing authorities.

This years breeding male (JN), is confirmed as a 2014 offspring coming from from the same site as the female (BX – 2011) both originate from the same breeding adult female at Cann Quarry . Both birds were ringed under licence at this popular site by Dale Jackson.

Talk for Rame Wildlife Group

South West Peregrine enjoyed presenting their Peregrine talk to the welcoming people of Rame Wildlife Group. The Village Hall in Millbrook was full of keen wildlife people to listen to the groups activities monitoring both coastal and inland Peregrine sites throughout Cornwall and into Devon.

The Rame Wildlife Group

Roger Finnamore talked extensively about the Peregrine the ringing and monitoring activities carried out by the team, along with lots of video clips interactive displays from the Groups Work.

We would like to thank Rame Wildlife Group for extending an invitation to us and our host Bruce Taggart for helping set up on the evening. The Team can be contacted for similar presentations throughout the year.

Peregrine Ringing

Sunday 4th June, another three young were colour ringed along with the metal BTO rings; this was a tricky site to reach, but the ledge was large enough to allow the ringing to go ahead in-situ.

This is a fourth consecutive season the pair have bred  and over that period 11 Chicks have all been raised to fledging. The ringing carried out under licence and with landowners permission went once again without a hitch, due to good teamwork and planning the climb in advance.

The Falcon does her best to protect three young chicks from a summer downpour. Weather play’s a huge part in the young’s survival; however with a good food source, and a well drained ledge, all three went onto successfully fledge in July.

This was this particular Falcons third successful breeding season, now having reared eight young in total.

Difficult climb is worth the efforts

Wednesday the 1st of June 2016, saw the ringing team back on the clifftops of North Cornwall at a particular tricky coastal site. A first attempt to climb was aborted,due to some technical issues. After a very difficult climb, the second assault proved a major success. Three very healthy eyasses bagged up in spite of only one adult being present for the past two weeks. The young birds were now at 25 days of age, slightly older than the desired ringing age by a day or so, but due to the their location on a very large ledge it was not a problem for the experienced team. They were a  bit of challenge to handle and ring, however the team prevailed. All three healthy young Peregrines, were then returned safely to their ledge some 100  feet below the cliff top. The adult male was soon back to inspect the goings on and in due course feed the ravenous young.

SWP would like to thank Chris Adams for photographing the team and allowing us to use his images on this post.

Helping with Buzzard Project

Roger Finnamore  of SWP gets his hands on some young Buzzards (Buteo buteo), he takes up the story

‘The Peregrine is obviously the core species of our field work, that said however, we do have other strings to our bow. The 1st of June, and I had kindly been invited to meet with George Swan. George has been carrying out a colour ringing project on Buzzards, the venue a large estate in mid Cornwall. Not quite knowing what to expect, George and I met at the appointed hour. He agreed to do the driving, an interesting journey followed as Cornish hedgerows flashed by. We arrived at the first chosen site and George was soon on his way up a substantial tree. A single chick was found at this site, duly bagged, lowered to the ground  ringed and  swiftly returned to the large stick nest. 

Again at break  neck speed, it was off to the next nest. Concentration of Buzzards took me by surprise and it wasn’t long before we were at the foot of our next nest. This nest held two much larger chicks,these were weighed, measured, ringed and returned. A completely new experience for myself; getting introduced to a new species a under the watchful eyes of  George was one which I most  definitely would like to repeat. Very many thanks to George for the opportunity’.

The Ledge

A short film put together from numerous Trail Cam clips on a pluming ledge and cache used by an adult breeding pair of Peregrine Falcons (Falco peregrinus). It was the groups first time using this kind of technology to aid our fieldwork and studies, therefore we are pleased with the results and the capabilities of the device. It is no doubt a useful tool.

In this short ‘Winter’ study we have managed not only to capture both adult birds utilising the cache, but it shows the Tiercel (male) was at times reluctant to share the spoils with his mate. The powerful neck muscles in the Falcon (female) are clearly visible in the clip and some interesting vocalisations are also picked up.

Clear evidence of nocturnal activities with the birds visiting the cache not only in dusk and dawn but also during the small hours as well were recorded. We did not pick up prey being delivered at this time, but it is an indication that birds are still active in these remote and unlit areas; on the lookout for nocturnal migrants such as Woodcock aided only by moonlight. These are regular prey species as recorded in the study by Nick Dixon and Ed Drewitt at Exeter (St.Michaels), the longest running Urban collection of prey samples.

The camera itself was hidden inside of a fake rock, so it was less obtrusive to the birds. In the first couple of frames it does appear that the birds are aware of the device, but they quickly became use to its presence and in some night shots it would appear they were even sat on top of the rock.

Field studies like this will hopefully lead us to a better understanding of prey taken at different sites, as well as the interaction between the adult pairs. It may throw up other interesting factors, such as intruding birds, the ability to pick up tagged birds or as in our case small mammals also feeding on the prey remains (below – image only).

An opportunity to witness Cooperative Attacks by Urban Peregrines on Common Buzzard.

Sunday 7th of June members of South West Peregrine joined Urban Peregrine researcher’s Nick Dixon and Andrew Gibbs, the co-authors of the British Birds Article ‘Cooperative Attacks By Urban Peregrine on Common Buzzard’ (May 2015 Issue), opposite the home of the study pair at  St Michael’s & All Angels Church, Exeter. A small team of watchers all alone on a multi-story car park roof, armed only with binoculars, scope, flasked coffee and notebook.

We had arrived early and already the Tiercel was in the air as we got into position, an alarm call being directed at the Falcon as he began to ring up (series of flaps and glide in a tight circle, gaining height on an early thermal) made him easy to pick out in the clear blue skies. The Falcon, now sat upright, alerted, on the gable end above the eyrie (a box installed and located behind a trefoil),looked on at her mate; calculating her route to join him. A Common Buzzard (Buteo buteo) came into our view, effortless gliding and roughly following  the course of the River Exe far below; at this point still unaware of the dangers of drifting into this ferociously guarded territory.

It is worth noting that the two young are only days away from estimated fledging with the young male expected to go on Thursday 11th of June (42 days from hatching). So no threat is directly posed to the young eyasses from this passing raptor at this point in time.DSC_2481

The Tiercel quickly reached a height just above the Buzzard, still hecking his alarm, the Falcon had by now left her perch and with rapid wing beats headed on a looping course behind the Church spire, climbing quickly to join her mate. Before she arrived in position the first stoop from the male on the Buzzard was witnessed, not a full speed attack and not directly at it, but in doing so the Buzzard now knew it was in danger. A second and more threatening stoop this time by the female made this threat intensify. The Male was now almost instantly, back in position above the Buzzard, who was heading in a South Westerly direction, within seconds the Tiercel was in again, quicker and now more threatening himself this time around.

Nowhere to hide

Calling from the pair could still be heard from our vantage point and we watched in awe as the Falcon was once again diving at the helpless buzzard; It flipped onto its back presenting its talons has a means of defence. It began to lose height deliberately and wing beats where seen has it tried to make its retreat. We witnessed 14 stoops in all before the Buzzard made good his escape and the pair turned back toward the spire.

What we witnessed as a group over the next 4 hours will go down as one of the most remarkable accounts in our relatively short 8 years as a group watching Peregrine Falcons together. Nine attacks in all where witnessed, both Adults spent the majority of this time in the air defending this territory only briefly returning to pitch in on the Spire or Cross, always remaining on high alert. Attacks seemed to be called off once the intruder was approximately 1km away from the Church Spire (in any direction) A number of hits on Buteo buteo where observed, these seemed in the main to be by the larger and possibly more aggressive Falcon.

The Maximum number of attacks by the pair on this beautiful morning was 45 in total; one buzzard was sent spiralling to the ground, seemingly having flown its last flight. However on trying to recover this bird it was seen making an escape first to a nearby tree and then into a clump of trees in a nearby garden. During this time both birds remained on high alert and 2 level flight attacks were launched from the spire until the were certain any imposed threat had passed.

We said our goodbyes at around 13:00, the afternoon watch was about to commence, what we had witnessed formed the basis of conversation all the way back to Plymouth.
