From Sokół wędrowny to Hebog Tramor

Peregrine falcon eye - from an image of a juvenile by John Salloway


Wherever you live on this earth - whatever language you speak - welcome to our peregrine falcon blog.
If English is not your main language, you can now translate any page of this diary. Just look for the Google Translation tool on the top left-hand side of this page.*

During the busiest part of the 2009 peregrine breeding season we know that nearly 10,000 readers a week came to learn more about events on the peregrine nest platform on Derby Cathedral's stone tower. Even now this blog still receives almost 1,000 visits each week, whilst the webcams themselves get around 500 visits a day.
The map below shows the typical spread of blog readers around our planet. It's good to see some of you appearing nearly every week on these maps. The more distant you are from Derby, the more your little red dot stands out. It may be invidious to name names, but "Jennie in Hong Kong" and "Ann (Canada)" are just two of a number of regular readers and commenters who have managed to make the long journey to the City of Derby to see our birds in person.
It's hard for us to really understand how effective our family of peregrine falcons actually is at bringing people to Derby, though we know many of you have made the trip, often combining it with a chance to go shopping. So if your visit or stay in Derby is prompted by our birds, do please make a point of telling your hotel/taxi driver/shop assistant/tourism officer or restaurant exactly why you've come. Or tell us about your visit by emailing peregrines@derby.gov.uk
Sometimes those little red spots on the map are easier to notice than real visitors in the street! Follow this link for more on Derby tourist infomation.

We've long been intrigued by regular visits from someone near Honolulu in Hawaii, and possibly from Cook Island or some other seemingly remote spot in the South Pacific. You guys appear nearly every week, so welcome, whoever you are.
Of course, Peregrine Falcon is Falco peregrinus in any language, because scientists use one internationally agreed name. But if you've ever wondered what other common names are given to peregrines around the planet, here are just a few we've found.
  • Sokół wędrowny
  • Wanderfalke
  • Vandrefalk
  • Faucon pèlerin
  • Halcón peregrino
  • Falco pellegrino
  • Slechtvalk
  • Bayağı doğan
  • Halcón peregrino
  • Πετρίτης
  • Sokol stěhovavý
  • Сокол скитник
  • Hebog Tramor

I wonder how long it will take someone to list which language is which!

The Jury's In.....

(Updated 10 Nov) Yesterday morning was fine and bright in Derby - if cold. Winter has arrived as you can see from the lack of leaves on the trees. Gulls were flying from their overnight roosts to feed along the river and perhaps in fields beyond the city's boundaries. A grey wagtail flew by and I heard the calls of a mistle thrush too.

Both adults were on the cathedral tower. The male was on the platform. While I was looking for prey remains he made the 'ee-chup' call above my head. I looked up and saw him glide from the platform, circle round and then fly over to the new hotel where he proceeded to sit on the Y of Jurys....just as Joyce S of Derby had also reported. I've also seen the female again on St Mary's, the roman catholic church, so it seems our Church of England birds are sampling both catholicism and now mammon....



There was not much in the way of prey remains - just a few snipe, lapwing and various thrush feathers.



The project team had a useful meeting with the hotel manager last week, discussing various ways in which the hotel might help the project next year. The birds themselves clearly haven't waited for a meeting- they've taken advantage of its presence already!

Postscript: The video below was taken in May 2009 as Jurys Inn, Derby, was nearing completion. It compresses 90 minutes down into 75 seconds, and shows our adult falcon looking out over the hustle and bustle of city life below. (Warning: Don't play the audio too loud)

Praise from London; Film from Italy

The newly formed London Peregrine Partnership has an excellent website, well worth a browse. In particular, go to their 'Peregrines on the web' page where they say (completely unprompted):

"The Derby Cathedral site is by far the best in the UK, with regular updates, good notes and some excellent pictures."


Obviously we knew this anyway but it great when someone else 'in the business', so to speak, thinks so too!
Well done that man at the museum - you all know who he is! What a star!

Herewith also the photo of the church in Exeter where peregrines have nested for many years and which was the stimulus for setting up our cameras back in 2006/7. You can't see the nest site with the cameras trained on it because it's round the other side of the base of the spire - and anyway, the annoying peregrines have decided to nest inside a window completely out of view both from cameras or the ground!

Update: Our own web cams are down at the moment, as you probably know. We now know where the fault lies, and are waiting for an engineer to arrange to visit the Cathedral to repair the wireless link connecting us to The Silk Mill museum. Please bear with us.
Meanwhile here is a lovely YouTube video made by Paulo Taranto of the life of urban peregrines in Bologna, Italy. (Watch for the zoom shot with the policeman)

Brief flirt with catholicism?

( Update 2nd Nov. We are aware of a power failure affecting our webcams today. We will try and restart our equipment over the next 24 hours)


The peregrines have switched to their usual winter diet already. This morning I found three redwing heads and one of a fieldfare below the tower, as well as a common snipe's beak. As you can see, most of its skull has gone - the brains are rich in protein.
Redwings and fieldfares are absent from Derbyshire in summer, returning here from Scandinavia each winter, some never to return of course.


I also saw a peregrine (the falcon) perched on the tower of St Mary's, the roman catholic church a few hundred metres away from the cathedral. This is the first time I've ever seen a peregrine on that tower, which is much lower than the cathedral tower but, nevertheless, a high vantage point for a peregrine. Sorry the pic is blurred - taken from the car while traffic lights were on red!
She didn't stay there long as it happened....

Burton neighbours


Here are some photos sent over to us of the Burton on Trent peregrines that nest high on the brewery tower in the middle of that town, some eight miles SW of Derby. Apparently they had three young this year.



The box was put up several years ago and the person who was responsible for it initially has now retired from the brewery. As you can see the box (just left of the bottom left of the red sign) is quite small compared to ours and it's no wonder that some juveniles come down to ground.
Apparently any fallers are quickly collected and taken up onto an acccessible flat roof where the parents can see and feed them.
The last photo shows one of the grounded youngsters. The whole site is secure of course, being an industrial complex.


More details on this site later when they come through.

Various updates

A couple of days ago, a birdwatcher reported seeing three peregrines on the top of the police HQ aerial, barely half a mile from the cathedral. The adults are on and off the tower as usual at this time of the year, just keeping an eye on things as it were.
We continue to monitor the prey species being taken. Corncrakes have appeared in the diet recently. These birds, while scarce in the UK, are not quite so uncommon in Eastern Europe where old-style farming is still practiced - eg in countries such as Poland and Estonia. These are migrants and when there's anticyclonic weather, the easterly winds blow them and many other eastern birds to our shores.

Corncrakes, like water rails, little grebes, quail and various waders such as woodcock are all night migrants and so are rarely if ever seen by birdwatchers as they migrate. By day, they hide away in fields, marshes or woods, keeping a very low profile.

Ed Drewitt tells me that peregrines in Warsaw take many corncrakes in the autumn, which is not perhaps surprising, given this predator's habit of nocturnal feeding.
Other species taken recently in Derby have included the usual golden plover and teal, both of which winter near Derby - plus at least one skylark. The plover may be in flocks several hundred strong, the teal - a small duck - winter in smaller numbers at most reservoirs, lakes and gravel pits in the nearby valley of the river
Trent.
We have recently made contact with someone who works for Coors Brewery in Burton on Trent and who keeps an eye on the peregrines that nest high on the company's tower which dominates the town's skyline. We hope to learn more about these neighbouring birds.

Meanwhile, here are two further photos of Cathy (010) taken when Nick Moyes and I went to see her and Colin a few weeks ago. We watched her come to Colin's fist, flying quite strongly across the ground. The injured wing though is clearly not producing the full thrust that she would need to fly properly.

Cathy doing well








Colin took this photo of Cathy (010) recently and isn't she looking well? More photos are promised soon.






Down under the tower on Sunday morning I found the lovely, recently moulted peregrine feather shown below as well as several prey feathers.


These included those of teal (a small duck) and woodcock (a wader) both of which are typically winter food for our birds....the year is definitely turning now.....




Just as well peregrines are not migrants (though they do get shot at in the UK of course - more on this later).....
