Three cheers

Three of our four chicks have now successfully hatched out, which is great news. The first emerged early on Saturday morning; the second hatching out on Saturday afternoon. By early Sunday morning we saw our third chick, though it probably hatched late the evening before, judging by viewers' comments. However, it seems we may not be successful with the fourth egg - but this sometimes happens.

For viewers new to our webcam and blog, do check out the comments left by other watchers below each post - it can often update you far more swiftly than our Project Team can, and people are often quick to respond to questions you may have.  (Sometimes comment moderation is employed which can itself lead to a delay in information appearing, but we keep this to a minimum). The pictures and video below have all been captured by our wonderful band of peregrine enthusiasts. Again, links to these may be found in the comments left, or you can check out our Flickr group for screenshots captured and uploaded.

Three chicks with an egg, and dad!

This 20 minute video by Wendy Bartter shows some lovely moments when all three chicks are fed so tenderly.

Who's The Daddy?

Our first chick of 2017 hatched very early around 04:37am today. Once again, it was one of our keen webcam watchers (BeeThistle) who spotted and reported this on the comments section of this blog.
Here are some initial screen shots taken this morning - first showing a broken egg fragment, then just a very brief glimpse of a tiny chick. (scroll down for the full video of this morning's events)



Don't forget to check our other cameras - the view from our new Cam4 on Page 2 gives a great, low-down view, letting you see the chicks more easily. As its audio isn't compatible with our streaming service, here's a live audio feed from another camera which you may want to run in the background. It stays on for longer than the cameras, and is a great way of monitoring next activity.

Once again, our webcam watcher, Wendy Bartter, has come up trumps with a great video compilation of this mornings action, together with a first glimpse of the newly hatched chick and its caring parents.






2017 has seen the latest ever date for egg-laying and hatching, as you can see by the chart on our Frequently Asked Questions page. Previously, the latest date was 10th May though, of course, this season has seen a significant change in the nest dynamics at Derby. As some blog readers may be aware, we now have a new male this year. This bird (with a ring on its leg) either ousted or replaced the previous (unringed) adult male (read more here). We still don't know precisely when he moved in, or indeed whether the eggs we see hatching today were fertilised by him, or the previous male, as the first evidence we had of his arrival was in early March - quite some time after we normally start to see the adult birds mating.

Watching and waiting . . . and now listening

Our webcams see their most traffic when our peregrine falcon eggs are about to hatch, with a second spike in views at fledging time. So right now is our most popular time.

Listen Now (20 minute timeout):



We currently have four cameras, two of which are new this year. Only the camera on Page 1 currently has sound, although we did purchase a second camera from Network Webcams with an in-built microphone and the ability to be remotely controlled, which you can see on Page 2.

Unfortunately, we discovered too late that the encoded audio from this new camera (Panasonic SW-175) was incompatible with Network Webcam's own Streamdays service, which we've used to great effect for the last 10 years. Having expressed our disappointment to Network Webcams, they offered to make good this shortcoming by providing us with a free "audio only" feed, taken from our other camera. This has a much longer timeout period (20 minutes) than three of our four camera streams, and so viewers might wish to click on the "Listen Now" button below to add in the missing audio.

As we watch and wait for what we are hoping will be imminent hatching, I'm sure many viewers will appreciate the ability to monitor the sound for that bit longer. If you wander away from your computer, leaving the sound running, you can dash back to restart the video feeds when you hear sounds of activity on the nest - perhaps a changeover between the adults.

Our other new camera can be found on Page 3, also with a 10 minute timeout. However, there is no timeout to the camera feed on Page 4, as this is series of static images which updates every 6 seconds or so. Viewers with limited internet connectivity, or a desire to run screen capture softeware (e.g Irfanview) all day long to capture those magic moments, may find this stream ideal.

If you do capture a moment you'd like to share with everyone, you can find details (here) of how to post them on our Flickr page.

Forthcoming events

There's a lot to look forward to in Derby this season.

Pretty soon we hope to be seeing the first signs of hatching of our (very late) eggs. We had a change of male this year, causing the eggs to be laid much later than normal as you can see from copy of our master timetable, normally found on our 'FAQ' page.
Extrapolating from past dates, we can expect hatching next week, around Wed 10th or Thursday 11th May.

We'll then be announcing our WatchPoint dates to the media though we can tell you that they will start on Saturday June 3rd and run every Wednesday and Saturday mornings until early July at least. This year we're expecting big crowds coming down to see the Weeping Window poppy display at the nearby Silk Mill Museum on Cathedral Green. Maybe we'll see some of you there?
