New Season Update

Updated 03 March (see end)

Spring is nearly upon us. With reports of peregrines already mating in the south of England, our own pair here in Derby are also showing clear signs of getting ready for this year's breeding season.

Already we are seeing courtship displays on the nest ledge. This involves both birds standing absolutely still on the nest platform, heads bowed down and facing each other. This may last for three or more minutes, and is often accompanied by a loud "ee-chupp, ee-chupp" call from the female. The multi-image shot on the left shows the female standing in the nest scrape just a few days ago, with the male standing on the right hand side. They were motionless. Unfortunately the pictures are a little misty, but we've since cleaned the lenses. And here's a clip from the 2008 season that we recorded to show you what happens.




The male always seems to lose his nerve in the end. After some minutes of head-bowing (or aggressive-sounding "ee-chupping") he flees the nest ledge, leaving her all alone. There she may pick at a few stones or, more frequently, may indulge in some nest-scraping . She will lie down on the ground and push back with her feet to create the hollow scrape in which her eggs will later be laid. All the images of the female in the series below were captured just a few days ago, on 24th February.


Food may also be brought back to the nest by the male, which he then passes to his larger mate, and we're receiving reports from webcam viewers that this is being seen too.

With the weather finally warming up, Nick Brown and I took the opportunity today to do some last minute spring-cleaning. This meant notifying the police before I made a quick abseil down from the top of the tower to the nest ledge where the cameras were cleaned and everything made ready for the new season. We also took the opportunity to help Derby Cathedral by cleaning out their gutters and even discovered a few minor roof maintenance issues which we'll be reporting back to them. It was less than an hour after we'd left the roof that the birds returned to claim the Cathedral platform as their own.

With the season advancing rapidly, do look out for mating. This happens very frequently through March, right up to the day of egg-laying towards the end of the month. Passers-by in Derby may be lucky to witness this for themselves, but webcam watchers also stand a good chance of seeing something. Our birds do seem to like the tower top in front of our camera, and over the last two years we've captured some stunning moments which are archived on this blog.

Have you seen a special moment you'd like to share? If so, leave a comment on this blog, or hit print-screen on your PC and post us the image. You can put them on our Flickr Photo Pool where over a 1000 images were uploaded by viewers last season.

We'll bring you more stills and videos as the season progresses, and hope you'll stay with us to share once again all the intimate moments of these very special birds' lives.
The number of hits we've had since the beginning of the year (now close on 50,000) is more than double last year's figure by the same time (19,000) and quadruple the 2008 figure (11,000)....due mainly to the world first 'night hunting video' which newcomers can still see by scrolling down to the post of 11th January....
The BBC's Springwatch programme has recently been requesting video clips of our birds so we are optimistic these may be shown in future....we'll keep you informed.

Update: In an attempt to resolve the problem of our video server freezing up every few months, Axis (the manufacturers of our video server) have recommended that we set our sytem to cease uploading to the internet for a short period each day. Being British, I've selected a time of 3am for our webcams to close for 15 minutes.  Sorry if this affects you as a world-wide viewer. I'll happily change the time we break - I just don't know when is best for minimum disruption. (All suggestions welcome)

  1. That is good news, I am glad the peregrines are going to use this nest again, they know which side ther bread is buttered.

    I did see the falcon in the gravel scratching about a few days back now. Can't wait for the season to start, as I missed the egglaying and hatching last year.

    Thanks for the report, I will keep my eyes open

  2. Thanks, Phoebe.
    I'd not realised you'd missed much of the events from 2009. Hope you catch all the live action this year.
    The 2009 video highlights are stil watchable here: http://bit.ly/cAXfKC

  3. Will it be possible for official?photographers to describe their cameras,lenses,settings,etc.this year?

    ReplyDelete
  4. @Nick, 3am sounds good for me, I think giving up 15mins will be worth it to avoid the cams going down at a crucial time, by the way the clocks here in N. America go ahead on March 14th, a little earlier then yours.

    ReplyDelete
  5. I don't think 15 minutes is going to bother anybody, unless a chickie starts to hatch at that time :-)

    Thanks again to everyone involved for the work that you do.

  6. From the top of a building in a city where there are many Peregrines, I blogged

    ( But on my corner up high I perch alone. Now I’m a raptor. I’m battle upgraded, twitchy, sociopathic and running an ultra-rapid pulse and I’m meticulously observant of plus or minus scenarios and I’m completely in the present moment. Only kill/no kill criteria register. I feel nothing else.

    And I am also a gargoyle on that corner, waiting frozen in the stone, and silently and without acknowledgment from even the rain I bow to total loss.)

  7. It looks like a lovely, sunny day in Derby. A lot better than freezing my toes off here in New England, wondering if Spring will ever come ;-)

    The animals must be feeling a winter food shortage here, as it's like Grand Central Station at my deck feeders at night, esp. the peanut feeder. Raccoons, skunks, foxes, often more than one species at a time, but relatively well-behaved towards each other.

  8. There's a wonderful close-up of an adult preening on the towe-cam!

  9. Me again, the bird up top is the tiercel I think, he is still there whilst the falcon sitting on the nest ledge. A lovey view of both.

    ReplyDelete
  10. One on the nestbox ledge rhs - female?

    ReplyDelete
  11. ... and another up on the tower.

  12. It has indeed been a lovely few days here in Derby City recently. The nights and mornings have been cold and still, but the sun has warmed everything it has touched.
    Up on the Cathedral tower this morning, as has already been reported, both male and female peregrine were sitting passively. Returning from a meeting at The Silk Mill museum, I took the chance to nip up the tower and browse quickly through the last few days of tower-cam recordings. As yet there doesn't appear to have been any mating moments, but we'll keep watching as it probably won't be much longer now. (8th March was the earliest recorded last season)

  13. One preening on the nestbox ledge lhs.

    ReplyDelete
  14. One just arrived on the nestbox ledge, lhs.

    ReplyDelete
  15. It's still there, having a leisurely preen at the moment.

    ReplyDelete
  16. One each end of the nestbox. Both are crouched down & they're facing each other. It almost looks like they're bowing or lowering their heads to each other.

    ReplyDelete
  17. The female has just spent several minutes in the nest side of the nestbox, re-arranging things by the look of it and crouching down in that shallow round depression, just as if she were testing it out for size/depth/comfort.

    ReplyDelete
  18. Peregrine on the tower plucking and eating prey. Wonder if it has just been caught?

    ReplyDelete
  19. One just arrived on the tower with prey, could be a pigeon.

    ReplyDelete
  20. Gone! And so has the prey I think. I wasn't watching so not sure.

    ReplyDelete
  21. One on the nestbox ledge, rhs. A glorious day, such blue sky!

    ReplyDelete
  22. I think it's the female on the nestbox ledge rhs but unless they're together I can't really tell which is which.

    ReplyDelete
  23. Large peregrine, probably female, IN the nestbox, rhs.

    Both present at 07:52 this morning. Female on the nest scrape, male at the opposite end

    ReplyDelete
  26. There's been a peregrine on the nestbox ledge rhs for about the last 40 minutes. Waiting for a bus???

    ReplyDelete
  27. Female, I think, scraping in the nestbox.

    ReplyDelete
  28. Now she's busy in the other side.

    ReplyDelete
  29. Just taking a break from cleaning the bathroom (oh joy!) and seeing both peregrines, one by the tower cam and one in the nestbox, rhs

    ReplyDelete
  30. One on the nestbox ledge lhs and one on the tower.

  31. Hey everyone
    An update on the "Sussex Heights" (Brighton) story. It seems that essential maintenance is needed on the building. There were initial concerns about the attitude of the management but all appears to be well. They are taking expert advice and are well aware of their legal duties. The maintenance will be postponed this season and the box will not be (temporarily) moved until the birds will not be disturbed. An explanitory letter from the management is available here http://www.sussexheights.org/wp/category/peregrine-falcons/

    ReplyDelete
  32. I see an adult on the corbels below the nest on left hand side, possibly the falcon.

    @sue
    Good news for now on the brighton nest!

  33. ferrel pigeon brought on to ledge at 1607 after courtship display on the box. mark murfin

    ReplyDelete
  34. A large peregrine on the ledge, possibly with small prey.

    ReplyDelete
  35. No peregrines visible but a tiny bird with a pale breast is moving about just below the central strap in the nest platform - not enough detail to identify it.

  37. @AnnieF. Thanks for letting me know. I've rebooted the video server, so hopefully it will run OK again.

    It's working perfectly now, thanks. I did wonder whether it was my pc, as it's been a bit "tired & emotional" recently!

  40. Peregrine right up close to the tower cam - quite scary!

    ReplyDelete
  41. Peregrine near the pudding cam.

    ReplyDelete
  42. one on the ledge below the nest

    ReplyDelete
  43. Does anyone feel, as I do, slightly uncomfortable about the intrusiveness of nest cams.

    ReplyDelete
  44. @ spyinthesky
    Only very slightly. On balance the advantages, e.g.monitoring the progress of breeding pairs and their young after the decimation of last century, and the brilliant educational tool they provide for youngsters, seem to me to outweigh any disadvantages. So long as the peregrines aren't worried - and they seem quite unconcerned - I'm in favour.

    ReplyDelete
  45. I can still see movement at the front of the tray, so I suspect what I thought was a small bird yesterday was just a bit of debris fluttering in the wind!

  46. One peregrine on the nestbox ledge - has just been in the scrape, squatting down - and another just arrived on the tower ledge with small prey (can't see what it is yet).

    ReplyDelete
  47. A very nice close-up at the moment on the tower cam of an adult eating prey.

    ReplyDelete
  48. wonderful shot of bird with prey

    ReplyDelete
  49. There has been a peregrine on the nestbox ledge (scrape side) for quite a while - facing the scrape but looking round.

    ReplyDelete
  50. It's still there - if it's the same one. That's a very long time! Has anyone else been watching who can confirm or otherwise that this is the same bird? And would this be pre-nesting behaviour?

    ReplyDelete
  51. spy,

    I don't think the nestcams intrude in the sense that the birds notice them in any significant way. There's the recurrent question, does the pudding cam generate some attractive warmth in the winter, since they seem to cuddle up to it.

    As to the privacy, you have a good point. Ideally we would ask, but we can't do that.

    So I hope the fact that the cams do no harm and they make so much beauty available to the world, and raise consciousness, esp. among children makes them okay.

    Plus with watchers, often fledglings are rescued who otherwise would die.

    ReplyDelete
  52. I think the tower cam is frozen

    ReplyDelete
  53. Female was on nest ledge, then male brought it some prey, she ate some and then flew off with the rest.

  54. @Pax Canada
    Thanks for this alert. I've rebooted our server yet again.
    There's a lot of food-exchange been going on recently: I retrieved a couple of video clips of this happening which I'll try and find the time over the weekend to edit and upload to the blog.

    Interesting question and comments about the ethics of webcams. Am interested to hear more people's views on the subject, rather than give my opinions.

  55. Intrusive?

    I'll be devil's advocate here and say that without the webcams there would likely be no peregrines, no project, no nest box, no volunteers, no Cathy with Colin, no 24hr protection of these birds and many less educated people about the subject :)

    'Intrusive' is the fact that we are very likely all watchable leaving our houses for the supermarket, followed around each aisle of the store and filmed coming home again - by dozens of such cameras.

    The peregrines have no concept of a camera, whether they are vaguely interested in it's shiny reflections or sitting on it for a tiny bit of warmth or not. Neither have they any concept of why the cathedral is there, what it is really for and why that rather handy nest box suddenly appeared one year.

    Don't feel you are intruding. If the birds felt you were, they would be off like a shot and the project team might well be prosecuted for disturbing a highly-protected wild species.

    Relax and enjoy the privilege that a tremendous amount of hard work continues to bring to us.

  56. Well said, Terry,very good points there and if I may say so very well expressed. Seconded!

    ReplyDelete
  57. Terry, I also second that - nothing more to say except let's enjoyt it!

    ReplyDelete
  58. One on the nestbox ledge rhs, has just scratched its head & now having a wash & brush-up.

    ReplyDelete
  59. There has been a peregrine in the scrape for some time (just flown off), moving round in the depression and looking up as if waiting for its mate.
