Leicester Cathedral Chicks

It has been a busy three and a half weeks at the top of Leicester Cathedral, with the resident Peregrine pair doing a great job at raising their chicks.  They have been back and forth with a good supply of prey items, feeding, stashing leftovers and generally protecting the chicks.  For a couple of weeks, the final egg remained in the nest, but on the 21st May I noticed that it had finally been broken and eaten.

With all the attention on just two chicks, the adults have been able to work well as a team so far, which as you can see is paying off as the chicks are growing well and looking very healthy!  Feather tips are quite noticeable now on their wings and tails, and they are becoming a lot more independent.  They are even walking around and sitting on the ledge!

On the 24th May, the chicks were colour-ringed by licensed ringers to help identify them this season as well as in the future when they have fledged and matured.  It’s nice to know that the siblings have also been sexed provisionally as one female and one male – how lovely!

This coming week, I expect to see a lot more body feathers push through their down, along with their wings begin to look larger and fuller.  The chicks should also open their wings more often and start running around the nest box and ledge.

Peregrine Falcons: The Latest

It has been a long ‘thirty days’ for anyone who has been following the Leicester and Nottingham peregrines since they laid their eggs at the end of March!  I have continued to keep my eye on the live cameras and have been impressed with how attentive both pairs have been – I literally didn’t see any of the eggs uncovered throughout the whole incubation period!

As May approached, I checked the Leicester Peregrines and NTU Biodiversity websites and social media pages more often for updates and finally, on the morning of the 5th May it was noted that the Leicester pair’s four eggs had decreased to three after the female had been seen eating one of the eggs along with the deceased chick inside.  This may sound horrible, but is quite common when an egg is damaged or the adult can tell that something is wrong, and by eating the egg the nutrients are recycled, energy is saved and the nest is kept clean.

The female continued to incubate the remaining three eggs and was looking quite restless as the day went on… it was time for some hatching!  At 1:30am on the 6th May, the first fluffy white chick could be seen.  Luckily, for those of us who were asleep, there is a fantastic thorough commentary down the right hand side of the live stream, which details the behaviour, feeding and interactions of the peregrines each day.  Let’s just say that the female is definitely the boss!  There are also some great and often funny videos which means we don’t miss a thing, such as the hatching of the second chick at 3:15pm on the 7th May!

I am so happy that the Leicester pair have been successful this year and am enjoying watching the chicks already.  The third egg still remains in the nest, but is very unlikely to hatch now.  Despite this, I say that two chicks out of four eggs is brilliant considering the pair had no hatchlings in 2017.  If you remember from my ‘Eyas Update‘ last year, peregrine falcon development is pretty rapid, so it will be interesting to see how they change over the next few weeks.  I can’t wait to see them exploring their nest box mansion!

Now from good news, to not so good news… the Nottingham peregrine falcons.  After an amazing nesting season last year, fingers have been crossed for Mrs P and Archie but sadly things aren’t looking good.  Back in April I blogged about how the weather had not been great and that Mrs P had struggled to lay her second egg.  It was also believed that because of the time gap between the first two eggs, she may have reabsorbed what would have been the second egg, and that the original first egg may not be successful.  Well it actually looks like none of the three eggs will be hatching this year.  On the morning of the 10th May one of the eggs and chick inside was eaten by one of the adults (most likely the female) and there has been no signs of pipping on either of the two remaining eggs.

I had been concerned from the beginning of May that this was going to be the case, as Mrs P remained hunkered down, hardly moving whenever I checked the camera.  She worked hard over the month with incubation, but unfortunately at this point the Nottinghamshire Wildlife Trust and NTU agree that it seems unlikely that the eggs will hatch.

Let’s stay positive though – we know that the Nottingham pair have been successful before, so they can have a rest this season and who knows, maybe next year they will be successful again!

Drama On The Peregrine Ledge

It has been an action-packed few weeks for the NTU peregrine falcon chicks.  After spending a week in Dartmoor (me, not the chicks) with little internet access, I returned on May 26th to discover that all four were out of the nest and exploring the surrounding ledge.  Most of their down had been replaced by stunning feathers and they were looking truly beautiful and elegant.

They have since been feeding themselves, flapping their wings, spending more time on their own and out of sight of the cameras, but on June 1st camera one captured something extremely dramatic (and a little bit funny if you keep watching it) which you can view in slow motion here.

As you can see, one of the chicks attempted to fly and ended up crashing into its mother causing them to tumble off the edge of the building!  Luckily both were fine and the chick landed on a lower ledge.  As the chick had not properly fledged and was unable to fly, it could not return to the nest, however it has been reported that the adults have continued to feed it!  Despite this, I (and I am sure many others) have been a little worried about the chick over the last few days in the rain and wind… and unfortunately I have some sad news.  After following the peregrine falcons throughout the whole nesting cycle, it breaks my heart to announce that earlier today the Nottinghamshire Wildlife Trust reported that one of the chicks (I am not entirely sure whether it was the one on the lower ledge) had “been killed yesterday on the road below the ledge”.  It is assumed that “it got blown off or lost control of a flight in the ferocious wind we have been experiencing”.  Obviously this is a terrible shame as the four chicks were each doing brilliantly, but it is important to know and remember that less than a third of peregrines actually reach breeding age, so the family have still done very well.  Those peregrines that do reach breeding age are expected to live for 6-13 years, but the oldest known peregrine was over 16 years old!  So let’s keep our fingers crossed for the remaining three!

Eyas Update

It is week four of the NTU peregrine falcon chicks’ development and I am honestly amazed at how quickly they are growing!  I noticed yesterday that the cameras were off for a while, so knew that it was ‘ringing time’.  It was exciting to later read that the Nottinghamshire Wildlife Trust and NTU Sustainability team had indeed finally ringed the chicks and found out that there are three females and one male!  To ring the chicks, the team waited for the parents to leave the nest and then quickly fitted a small, lightweight, harmless, metal ring around the leg of each eyas.  Ringing birds is essential for bird conservation as it helps provide information about their movements, locations and lifespans.

Some brilliant photographs taken during the ringing process.  (Thank you for these Emily).

The images below are just a few stills from the NTU live stream that I have saved.  Archie and Mrs P have been providing a constant supply of feral pigeons and other medium sized birds for the eyases and as you can see in the fifth image, their crops have been nice and full.  Although one chick is smaller than the others (and has been nicknamed ‘Diddy’ on Facebook) all four are getting their fair share of food… I even caught one of them possibly ‘gaping’ for food whilst both parents were away, which you can see in the sixth image!

On May 13th, I noticed that all four chicks were starting to grow their flight and contour feathers, and yesterday (16th) the new darker feathers were poking through their down quite clearly (image eight).  The chicks may have changed a lot already, but we still have plenty of development to see.  At this stage they have gained a sharp eyesight and are very interested in anything that moves – whether it be a fly or blowing feather.  Their legs are getting stronger and they are a lot more active in the scrape.

In the next week or so, they will lose most of their down apart from a few tufts on their heads (hopefully – for our amusement) and will be showing off their juvenile feathers.  We may see them flapping their wings and before long, in week six, the eyases may fledge the nest for the first time!  They should remain around the nest-site for a few weeks, during which time they will become adept at flying, pursue other birds and capture their own food, but will still rely on their parents for most of their food.  Around August they will leave the nest for good… and I must say that I will certainly miss watching them!

The Fourth Peregrine Chick

As hoped, today was the day that the fourth NTU peregrine falcon chick hatched out of its egg.  I checked the live stream at 13:15 after my sister messaged me about them… and there it was, it had hatched just before 1pm!  The male was feeding the larger chicks a feral pigeon as chick number four (being less than half an hour old) was getting used to the world and its siblings.

After a few minutes, Mrs P returned to the scrape and I just managed to save a still image of the whole family together!  WARNING: Some may find the below image disturbing.

All four chicks (eyases) are being kept warm and fed and are looking healthy and ‘wide-beaked’ this evening.  Peregrine falcon chicks eat a tremendous amount of food and if all goes well, this time next week they will have doubled their weight and in three weeks, will be ten times their birth size!  I am very much looking forward to following their progress over the next six weeks or so as they rapidly get bigger, grow juvenile feathers and eventually fledge the nest.  Once they start to fly they will depend on their parents for a few further weeks to learn how to hunt, so Archie and Mrs P still have a lot of work to do… and we still have a lot of great things to watch!
