Chicks!

During the week the peregrine chicks have hatched. The adult pair might have their hands (wings?!) full raising 4 chicks to fledglings over the next few weeks, especially considering a peregrine chick doubles in weight every 6 days!

Looks delicious

f-food

Peregrine falcons have been known to prey on nearly 140 species of bird in the United Kingdom. Although (thankfully) the resident pair in Plymbridge Woods do not enjoy that full menu.

As chicks approach the birds are frequently being seen on the quarry face stashing food in nooks and crannies on the rock, these are called caches and serve a very important role. It’ll help the birds maintain a steady flow of food to newly hatched chicks, particularly if the weather is unsuitable for hunting or if there has been a period of unsuccessful hunts.

Whilst the prospect of a 4 day old magpie carcass might not be appealing to many humans, it’ll still provide vital protein, water and nutrients to chicks.

Eggs and nest found at last!

The Plym Peregrine Project team are happy to confirm that the resident pair have nested, we were able to confirm 4 eggs on a nest tucked away in a nook on the quarry.

_DSC1903_fhdr

This marks the 6th year the current pair have nested. They might be getting old, but they never fail to surprise us!

Typically, once the nest had been confirmed it turned out that it had been in view of the viaduct the whole time! Volunteers were able to see the falcons rear feathers shuffling about as she rolled the eggs. We aren’t sure when the eggs were laid so we will be keeping an eye on the birds behaviour to indicate when they might begin hatching.

Come and visit platform to see the proud parents to be and their nest.

A little about the resident pair

Whilst we wait for the pair to give us some hints as to their nesting plans this year we get a good chance to quickly look back at the current adult falcons who call Plymbridge Woods home.

By no means are the the first pair to use the quarry face as a nest site. Peregrines have been active at the site at least 20 years, perhaps even over 50 years. A resident pair will have to fend off the territory, swooping in on any perspective new feathered tenants who swing by to check the place out. The victors keep the territory.

This pair first moved in back in 2011 making this their sixth breeding season in the Plym Valley. They have held the territory against countless other peregrines; even so far this year they’ve seen off at least 6 unwelcome intruders.

During their stay, they have had 10 chicks successfully fledge and leave the nest; 2 in 2011, 3 in 2013, 3 in 2014 and 2 in 2015. Unfortunately, the damp and miserable summer in 2012 meant the chicks were not successful.

One of their chicks from 2011, catchily named BX, was discovered with a nest of her own on Dartmoor in 2014, meaning the current pair are grandparents.

The falcon is easily identified by her hanging talon in flight and the tiercel by his faded chest feathers.

The pair are now entering their twilight years, so it’ll be interesting to see what happens during the current season. But they’ve surprised us before and it’s safe to say they’ll do the same again.

Still waiting!

This season is fast becoming a bit unusual. So far, although the pair are around the quarry there has been no sign of a nest site. Maybe this is due to their advanced age or due to the mild winter? Or maybe they’ve nested just out of site from the viewing platform (how inconsiderate of them!).

Regardless of this, clearly the resident female isn’t feeling her age as she flew into the quarry having a bit of a snack on the go.

Hopefully we’ll get some clear answers soon, but the pair are still giving us plenty to see!

A week of mating and waiting

We’ve had an exciting first week of the Peregrine Project for 2016. The birds have been performing courtship rituals and mating regularly. We have been able to confirm that the birds are the same nesting pair as last year, making this their sixth year nesting in the quarry. The falcon is recognized by her distinct talon that hangs in flight and the tiercel can be recognized by his fading breast feathers.

2016mating

Whilst the pair hasn’t picked a nest yet, a lot of their activity has been focused on an old ravens nest the pair has used previously. We are just waiting for the falcon to settle down and lay some eggs before we can confirm the nest location.

An absolutely stunning Good Friday gave the birds the opportunity to stretch their wings; they flew high on the updrafts until they were nothing more than specks against the blue sky.

Hopefully there should be some eggs towards the end of the month.

What a difference a day makes

The public viewing platform opened on the 23rd allowing the the volunteers to enjoy a fair range of weather over Easter; glorious sunshine on Good Friday followed by heavy showers on the Saturday.

The 2016 Peregrine Season is fast approaching

With spring just around the corner all sorts of birds have been getting ready for their nesting period, including the pair of peregrines that have been making a lot of noise in Plymbridge Woods.

The Plym Peregrine Project platform is due to open on March 23rd. Feel free to come and have a look at these magnificent birds as they prepare to raise another clutch.. Maybe you’ll be lucky enough to see the falcon laying her first egg!

Picking a nest for a new season

The 2016 peregrine nesting season is fast approaching! The pair of birds in the quarry have been scoping out a potential nest site, or eyrie, to use for the upcoming months. Peregrines will nest on a ledge and don’t build a nest themselves, rather they will acquire a nest from a different species or they will simple scratch out a shallow bowl on an appropriate ledge. We’ll be keeping an eye to see where they nest for this season, whether it is an old site or a new one.

The nest site during the 2015 season was a scratched out 'bowl' on a ledge.

Norman Moore

We recently became aware of the passing of conservationist Norman Moore. Whilst I never had the pleasure of meeting him I was well aware of his work. Norman played a large part in the research during the 1960’s that identified the impact of DDT on bird of prey species. Particularly peregrine falcons and sparrowhawks. This research helped forge lasting policy and protection that has led to the slow recovery of nesting birds of prey.

Norman passed away on the 21st of October, aged 92. Obituary in the Guardian.

A glimpse of the fledglings

In the weeks since the 2015 peregrine season ended the Ranger team have had a few sights of the juveniles in flight together around Cann Quarry. The pair are both still going strong as the time for them to leave. The size difference between the female and male chick was clear as the falcon overshadowed her brother. Whilst the Ranger team worked on the ground, the fledgling pair called loudly as they chased each other playfully through the air.

Soon the young will leave the nest area for good. Their biggest challenge will be this coming winter as they become exposed to the elements and have only themselves to rely on for feeding. In the wild only a third of peregrines survive their first year.

Peregrines are able to breed at 3 years old. Until then they will explore their surroundings venturing as far as they need to in order to survive.Once they are able to reproduce they will find a suitable habitat and seek a mate. It is a tough challenge for the peregrines to reach this point.

Personally, I hope that in 3 years we hear about KT or KV on a nest with successfully chicks of their own.

Wrapping up the 2015 season

The fledglings have been spotted bringing catches back to the quarry and taking extended flights around and beyond the Plym Valley. They will still try and grab a free meal from Mum and Dad when they can, and have been enjoying emptying the food caches their parents hide around the quarry face.

The recent heatwave has been beneficial to the young peregrines as they soar to remarkable heights effortlessly on the warm updrafts. Slightly closer to Earth, they have been mastering the art of airborne food passes and several bits of dinner have been lost beyond the trees below. Despite this the fledglings have been seen successfully passing food during inverted flight providing an impressive sight to visitors and volunteers on the viaduct.

It is close to two months since the young first hatched and the difference in their appearance is remarkable. In their first 6 weeks they grew from tiny balls of white feathers to full-size fearsome raptors. From slow waddling chicks to the fastest creature on the planet.

With the fledglings becoming less dependent on the nest site as a feeding site and roost it is time for the Plym Peregrine Project to begin wrapping up for the season. The public viewing platform will close after this Sunday 5th July. Over the summer months we will continue to keep an eye on the peregrines, and we will continue to post updates on their progress.

Still sticking together

 

KT AND KV

Seven weeks have passed since the fledglings at Cann Quarry hatched. The two young have spent the last week enjoying short flights around the quarry as they continue to strengthen their wing muscles. Having now mastered landing they no longer need to crash land in large areas allowing them to perch all around the Valley and explore their surroundings. http://www.plymperegrines.org.uk/still-sticking-together/ http://www.plymperegrines.org.uk/still-sticking-together/ http://www.plymperegrines.org.uk/still-sticking-together/ http://www.plymperegrines.org.uk/still-sticking-together/ http://www.plymperegrines.org.uk/still-sticking-together/ http://www.plymperegrines.org.uk/still-sticking-together/The juvenile male (KT) is particularly curious about his surroundings and has been spotted walking along the top of a camera in the quarry giving it an assessment.

Despite fledging a few days later than her brother, the female juvenile (KV) has quickly caught up in flight. Both are still sticking together and can be seen flying side by side around the Valley, sometimes playfully swooping at one another as a way to get to grips with hunting tactics.

A little bit about Mum and Dad

The current breeding adult Peregrine pair have been nesting in Cann Quarry every year since 2011. They took the quarry territory from an aging pair and have managed to hold off many prospective successors since. The two current chicks represent their fifth breeding year and make a total of 10 fledged offspring from this pair.

Female Peregrines (Falcons) are a third larger than the males. If you want to differentiate between the pair a size comparison is often the easiest way. Luckily the Plym Valley falcon has distinctively darker feathering on her head and, for unknown reasons, she has a limp talon that hangs whilst she flies.The male Peregrine (Tiercel) in the Plym Valley can be identified from the slightly lighter feathering on his head and by his fading front feather pattern.

Male and Female 06-04-15The Tiercel and Falcon on the nest during the 2015 season

They were able to raise sucessful chicks during their first mating year in 2011 producing two female chicks.  As the young chicks were rung we were able to track their progress. One of the birds from this brood was spotted on Dartmoor last year raising her own chicks, making our pair grandparents!

The pair returned to the quarry in 2012 for their second nesting year. Unfortunately, the summer of 2012 was the wettest summer on record for 100 years. The resulting rainfall and lower tempuratures meant that the chicks were unable to survive their first few fragile weeks. Sadly, no chicks left the nest this year.

Following the events of the previous year, in 2013 the breeding pair took over a nesting site previously used by ravens. This nest provided shade and shelter and they were able to raise a successful brood of 3 chicks who mostly left the nest.

In 2014 a familiar face had returned. A male juvenile, nicknamed ‘Junior’,  from 2013 had refused to leave home. The breeding pair had the challenge of raising 3 chicks whilst Junior stole food, made a fuss and caused havok. Ultimately, the 3 chicks succesully fledged and left the nest. However, Junior’s fate remains a mystery. He was last positively id’d in November 2014 and by now if he has survived will have his full adult plumage.

2014 24The returning juvenile during the 2014 season

There has already been plenty of action during the 2015 season. The pair have successfully fledged 2 chicks from an initial brood of 3. They still have several more weeks of hard work ahead of them in order for the young to have the best chance of surviving their first winter in the wild where the mortality rate is 70%.

Both chicks have taken to the sky

KT  02

Just a few days after the male chick (KT) fledged on Wednesday the female chick (KV) has taken her first flight on Saturday 20th June. She was seen in the air with her brother before landing on the quarry and being fed by mother from a cache. http://www.plymperegrines.org.uk/both-chicks-have-taken-to-the-sky/ http://www.plymperegrines.org.uk/both-chicks-have-taken-to-the-sky/ http://www.plymperegrines.org.uk/both-chicks-have-taken-to-the-sky/ http://www.plymperegrines.org.uk/both-chicks-have-taken-to-the-sky/ http://www.plymperegrines.org.uk/both-chicks-have-taken-to-the-sky/Understandably, that 2 minute flight was exhausting and after 3 hours of rest she took to the air once more, this time with the adult Falcon, circling and soaring on the updrafts from the afternoon sun. Although she took a little while longer to take the initial leap than her brother her confidence developed quickly.

KT FLIGHT 01

With four Peregrine Falcons flying around the quarry there is always action going on. As their wing strength continues to develop they will be taught flight skills and hunting tactics, often in and around the quarry. However, for now they are still fed from prey the parents have brought in.

All that flapping was a sign – First Chick fledged

First Fledged

Upon opening the peregrine platform this morning we were greeted with only one chick in and around the nesting ledge. After a fair bit of scanning the quarry with our binoculars and a good listen we were able to locate the other chick clinging to the quarry face on the right hand side. We were able to make out the id tag on the unfledged chick which turned out to be KV. http://www.plymperegrines.org.uk/all-that-flapping-was-a-sign-first-chick-fledged/ http://www.plymperegrines.org.uk/all-that-flapping-was-a-sign-first-chick-fledged/ http://www.plymperegrines.org.uk/all-that-flapping-was-a-sign-first-chick-fledged/ http://www.plymperegrines.org.uk/all-that-flapping-was-a-sign-first-chick-fledged/ http://www.plymperegrines.org.uk/all-that-flapping-was-a-sign-first-chick-fledged/ http://www.plymperegrines.org.uk/all-that-flapping-was-a-sign-first-chick-fledged/ http://www.plymperegrines.org.uk/all-that-flapping-was-a-sign-first-chick-fledged/This meant that it was KT who had taken to the air first and was now wondering what to do next!

With all this going on the volunteers on duty were even more excited when they witnessed our resident pair successfully hunt together in the area around the quarry, bringing home a wood pigeon from the other side of the valley. A very rare occurrence for our pair who obviously saw an opportunity to good to miss.

How long till KV is ready to take to the skies?

Have feathers will flap

zz_DSC8231

The chicks have become noticeably more active over the last few days, venturing further and further away from the nest ledge. Frequent flapping can now frequently be seen as the birds start to build up their flight muscles. Although they are more adventurous they seldom venture far from each other.

Despite being almost fully grown the chicks can still be hard to spot. http://www.plymperegrines.org.uk/have-feathers-will-flap/ http://www.plymperegrines.org.uk/have-feathers-will-flap/ http://www.plymperegrines.org.uk/have-feathers-will-flap/ http://www.plymperegrines.org.uk/have-feathers-will-flap/ http://www.plymperegrines.org.uk/have-feathers-will-flap/Their brown feathers acting as good camouflage against the quarry rock face especially when they are having an afternoon snooze.

Chicks entering their fifth week

IMG_1470

Taken through a scope this photo shows KV on the left, Mum in the middle and KT on the right

With most of their infant fluff (down) gone, the chicks are fast beginning to resemble a typical peregrine. Their dark juvenile flight feathers provide a stark contrast to the white down we have seen during the last 5 weeks.

With their flight feathers developing fast, the birds continue to become more and more active. They continue to venture further along the nesting ledge providing fantastic views for visitors on the viewing platform. Frequent wing flapping helps to increase their muscle strength and aids in shaking off any loose down. On average Peregrine Falcons fledge at around 40 days old.

The adults continue to feed the chicks regularly and full crops can often be seen in the young. The parents continue to take turns keeping an eye on the chicks and frequently perch around the quarry. http://www.plymperegrines.org.uk/chicks-entering-their-fifth-week/ http://www.plymperegrines.org.uk/chicks-entering-their-fifth-week/ http://www.plymperegrines.org.uk/chicks-entering-their-fifth-week/ http://www.plymperegrines.org.uk/chicks-entering-their-fifth-week/ http://www.plymperegrines.org.uk/chicks-entering-their-fifth-week/Often they will perch on the opposite side of the valley, showing off just how impressive their eyesight is. Luckily, we have added an additional telescope facing in this direction so that visitors to the viewing platform can enjoy the spectacular views of the Peregrines offered by this perch.

New Volunteer Peregrine Ranger – A little about me

Shannon O'Grady 01

Hi everyone, my name is Shannon and I am the new volunteer Peregrine ranger you may have met me on the viewing platform or around Plymbridge. I am here as a full time residential volunteer and am lucky enough to be living on site at Miners cottage. My duties will be split between covering shifts on the platform, opening/closing and other practical duties here in the Plym Valley.

Prior to arriving in Plympton I was volunteering for the National Trust on the Lizard peninsular for 12 months, I was working as part of busy and dynamic team to care for high profile and well-visited section of Cornish coast. This involved managing many miles of the South west coast path, coastal grasslands and woodland along the Helford river. http://www.plymperegrines.org.uk/new-volunteer-peregrine-ranger-a-little-about-me/ http://www.plymperegrines.org.uk/new-volunteer-peregrine-ranger-a-little-about-me/ http://www.plymperegrines.org.uk/new-volunteer-peregrine-ranger-a-little-about-me/ http://www.plymperegrines.org.uk/new-volunteer-peregrine-ranger-a-little-about-me/ http://www.plymperegrines.org.uk/new-volunteer-peregrine-ranger-a-little-about-me/There is a project similar to Plym Peregrine project, looking after the rare Cornish Choughs on the Lizard Wildlife Watch point and I was part of that successful project which has just seen five healthy chicks fledge!

When we meet you may notice I have a strange accent, this is partly because I am Australian, and partly due to travelling through Canada for two years just before arriving in the UK. I have had some amusing guesses from people about where I am from, so I hope that clears it up! I am looking forward to many hours watching the magnificent Peregrines and the progress of their chicks over the next few crucial weeks, and I hope to see you up there!

- Shannon O’Grady, Volunteer Peregrine Ranger.
