May 3 update

Plenty of feeding taking place today and I think there may now be 3 chicks. Their heads are becoming more visible by the day so it should soon be very obvious how many chicks there are. Female seems to be doing most of the feeding at the moment with the male bringing in the food.

I hope the chicks are more sensible this year when they are bigger and don't get too adventurous too soon - the ledge by the nest isn't very wide! 

Watch their progress here

Update 30 April

Great news, at least one chick has hatched over the weekend. The female spent 10 mintues or so tearing off little morsels for a chick this morning. I could just make out a little white head wobbling around. As I write this the female is back brooding the chick and the remaining eggs. Apologies for the quality of the photo, the only way I can get screen shots of any activity is to photograph the screen.

April 10th: There are eggs

The female started incubating on the 20th March so, all being well, we can expect the first chick to be hatching in the latter half of April. There was relatively little sign of the pair earlier in the year and the report of a dead Peregrine in Alexandra Gardens just before Christmas was a cause for concern!

With so little displaying and calling around the tower I was quite surprised to see the female begin brooding in late March, let's hope this pair is successful.

Or at least the Peregrines do. There was a worrying moment yesterday morning when I didn't see any activity around the nest for hours, I couldn't see a bird on the nest - and it was raining. I eventually saw the female at the nest late morning but she just had a cursory glance at the nest then flew off.

She returned a little while later and then sat on the nest for the rest of the day. The male flew in a couple fo times and on one occasion I am pretty certain brought in a little lump of food. The female didn't stir but it's possible the chick hatched sometime yesterday (or over the weekend).

When I switched the camera monitor on in my office this morning I saw the female was sitting on the nest then the male popped in with a morsel of food. The female stood on the edge of the nest, started tearing small chunks off and was stretching into the back of the nest to offer the food to the chick. This went on for about 10 minutes until the female resumed incubation.

Peregrines normally lay 3-4 eggs and start incubating as soon as they lay the first one, which means the first egg laid hatches first. Assuming the other eggs hatch there will likely be more chicks over the next few days but it could be a couple of weeks before they are big enough to be seen over the rim of the nest.

As with last year the Peregrines were around over the winter, I could see, or hear, them from the office most days. It seems August/September is when they are least visible, probably while they are moulting their feathers after the breeding season.

The camera was back up and running in mid-March just in time to see the female start incubating eggs some time around the 20th.

Let's hope that they have a better season than last year!

At long last the female has been seen carrying food into the nest so we know at least one egg has now hatched.

As the eggs are incubated as soon as she lays them the others should hatch at 1-2 day intervals.

Breaking news

Female appears to have started incubating.

Welcome to the 2011 season of Peregrines on the Clock Tower.

There has been plenty of activity around the tower in the last few weeks - in fact the adults have not left all winter. Perhaps more surprising is that 2 of the youngsters from last year have also been putting in occasional appearances.

3 weeks ago the young female was flying around calling for food when the adult male flew in clutching a bird in its talons. Then last week I was lucky enough to see the young male tearing at a carcass alongside his mother - who didn't seem to mind the intrusion, although he only butted in once she had eaten her fill!

The bad news this, as far as we're concerned, is it looks like they're going to use the nest on the north face of the tower. This will make life difficult for all of us trying to watch what's going on.

It's not all doom and gloom though, we can still see the nest - just not as well as the one on the east side - and we'll be able to see the adults bringing food into the chicks a little later in the summer.

Here's to a successful 2011 season.

Well, it's all been happening in the last few weeks!  

As you know from the last post, we lost one of the four original chicks around 23 May. On Saturday 29 May it was a rainy day and so we limited the event to the Museum. Then, at about 12.20 a lady rushed into the Museum to say that some people outside near City Hall had found a chick on the pavement and were "kicking" it to make it fly off. James and I rushed outside to see what was going on and there was a chick on the road, surrounded by people. It obviously had jumped the nest a bit too early, as it couldn't fly yet.  

So we contacted Adrian Williams, local falconer who we're consulting with, who came down to check it over. He said it was fine, just a bit underweight. James and Adrian took the chick back to City Hall roof where the chick was placed just under the clock tower. By the bank holiday Monday, the bird had made it back onto the tower, but not to the nest. 

In the week or two after we have only ever seen two juvenile birds at one time, so it looks as if the third one did not get enough food from its parents and was out-competed by its siblings. Sad news. 

However, the remaining two are now flying! They're coming up against their own challenges as the gulls try to mob them as they practice their flying skills, but it doesn't seem to be deterring them from making significant progress. They're beginning to look quite adept, so do come down and see us soon, as we'll be seeing some aerial acrobatics as the young birds get taught their hunting skills by the adults.

One of the peregrine chicks has died. We are now down to three chicks in the nest.  

Staff, and our peregrine-cam visitors, noticed yesterday that there were only two chicks in the nest. So our first thought was that we had lost two!  

Luckily the third chick returned to the nest in the evening after having been on a journey around the clock tower ledge.  

Today the RSPB project officer has spent the day looking for the fourth chick, but to no avail. It seems unlikely that the chick is still alive.  

One possible explanation is that the chick was the weakest of the four, and that the hot weather over the last few days has been too much for it to cope.  

The three remaining chicks look very healthy and have a very good chance of surviving, particularly as the weather seems to be getting cooler.
