A food pass… (sort of)

There was a flurry of commotion over the weekend when all 4 fledglings were up in the air. 3 of them were chasing after the ringed male (Wilfred) and making a lot of noise.

Wilfred was carrying something of particular interest, a scrap of food maybe? An old catch that he had taken from a cache? No not quite…

Its a stick!

One of his brothers still clearly wants it though.

“Give it to me!”

Of course, this aerial play is beneficial to the birds as it will develop the flight skills essential to survive on their own once they leave the nest and will help them avoid sticky situations.

2016 Peregrine season wrapping up

With the chicks in the air and rapidly becoming more independent the Plym Peregrine Project will wrap up on Sunday 10th July. After this, the team will continue to monitor the birds and ensure that their nesting site is secure.

Exploring their territory

The chicks have now all fledged. All 4 of them have been seen playing together in flight and exploring the quarry. The picture below shows one of the juveniles having a rest between flights.

The picture also clearly shows the vertical chest stripes of the young. Mature peregrines have horizontal bars on their chest.

Chicks in the air!

Theres been a bit of speculation as to how the chicks have been spreading themselves out on the quarry, today we have our answer with the first confirmed sighting of a chick soaring through the sky!

And then there were 4?

In an odd twist today, the volunteers spotted 4 chicks on the quarry face having an explore. We knew we originally had 4 eggs and then young chicks in quite a small nest, then at the end of May we were disappointed that there were only 2 chicks on the nest during the bird’s ringing. We assumed, given the size of the nest, that the other 2 chicks had been knocked off to their demise as they were nowhere to be seen.

However, this morning the team identified 4 chicks on the quarry alongside both adults. They have only just emerged as they explore their surroundings and fly for the first time, so it was quite a surprise. This means that wherever the chicks had fallen to the adults continued to feed them. All of the chicks look healthy, although it does mean only 2 are ringed – hopefully their unringed siblings don’t get jealous of the bling.

… whilst the other one is being fed by mum.

When Mum takes the food to the others, the lone chick follows (you can see it lurking in the shadows!).

If you want to get a view of these fantastic birds as they begin to learn the arts of flying, hunting and survival pop along to the project where our brilliant team of volunteers will be on hand to give you the best views possible.

Just going for a stroll

The volunteers spotted one of the chicks walking, climbing and leaping around the quarry over the weekend. We saw this behaviour last year as the chicks familiarise themselves with their surroundings and test out their courage!

We can’t see if this is the male or the female chick, but they have managed to cross the entire quarry and perch on a tree below Dad’s favourite spot.

Hopefully it’s able to down from that branch! But it’s only a matter a days until they spread their wings for that first flight.

A quick chick update

The chicks are growing fast. Now they are over 3 weeks old the first of their flight feathers are poking through. Soon all of their white fluff will be gone and they will take their first flight. This photo, taken during BTO ringing, really shows how much fluff they have to shed! Unfortunately, there are now only 2 chicks, but both are looking very healthy for their age.

Feeding Frenzy

With the chicks rapidly growing, the parents have been on a continuous cycle of hunt, pluck and then feed – although admittedly there is frequently some siestas in there when the weather is good!

f-food

 

Both adults will hunt. The females larger size allows her to catch larger prey which is beneficial when hungry chicks growing fast. There might be a food pass in the quarry when the food is brought in, we’ve seen the female passing a catch to the male who will then perch on the quarry and pluck the feathers of the catch ready to take to the chicks.

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!

ppp-chicks

Looks delicious

The resident falcon is seen below flying in the quarry with a bit of lunch.

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.
