Battersea Power Station Peregrines 2016

The 2016 breeding season was always going to be a challenge to the Peregrines, works have now begun in earnest on the Power Station itself and the skyline had dramatically changed with ongoing construction, new buildings, chimney demolition and Luffer Cranes.

With 3 successful seasons behind them due to our new female’s arrival in the winter of 2012/2013, 2016 heralded another new breeding season, the pair as ever took it all in their stride.

Would the works and the ever changing site perhaps send them off looking for pastures new?
It did occur to me many times, but the site faithfulness of the pair again reasserted itself and they laid their first egg on March 15th.

This year Battersea Power Station Development Company had installed CCTV, no less than 4 cameras watching their every move. It gave me a comprehensive insight to study the species even further, along with providing incredible live footage and images.
In total she laid 5 eggs with the last being laid on March 24th, this was also my first clutch of 5 in London. Laying durations between eggs were very consistent, 53 hours between eggs 1 to 4 and 55 hours between eggs 4 to 5.

The 5 eggs did create a problem for the Tiercel, his smaller size occasionally leading to one egg not being covered, sometimes for long periods in relatively cold weather.
This may have been a contributing factor in only 4 of the 5 eggs hatching, the first hatched on April 26th with the 4th hatching on April 30th.

On a diet of meat they quickly grew and all fledged in early June, one however did it the hard way and grounded on his first flight.
A Falcon Recovery Plan was in place particularly for this sort of occurrence; he was thankfully seen and located, placed in a box and then taken to a special safe area high up on the Power Station.

Battersea Power Station Development Company and construction contractor Skanska had set aside this non disturbance area on the Power Station specifically which I knew the adult peregrines used, it worked a treat and he was fed by the Falcon the same day.

Before long he joined his siblings, who also fledged shortly after, gracing the skies in and around the Power Station, by the end of the week all 4 had made it to the summit of the brand new south western chimney.

To have 4 screaming juveniles chasing an adult with prey around the Power Station construction site is truly a remarkable spectacle, obviously it has not gone unnoticed by the 3000+ workforce.

If you know peregrines, you will know how loud juveniles are when they are hungry; on occasions they even drowned out the noise of the site.
Many of the workforce have often stopped me to discuss the birds and get the latest, even on a major construction site there is a place for nature and it is good to see people taking an interest.

To date the 4 juveniles are spending more and more time away from site exploring and presumably hunting the adults territory, similar to teenagers they only return when they are hungry.

Pretty shortly I suspect the male juvenile will leave site, probably in September and then his 3 sisters will do the same, not long after him. Having said that, there is always one young one, as we’ve seen last year and in 2014, who takes a little longer to make their move.

Juvenile Mediterranean Gulls

July 27th 2016

Although still very early in the year I made a visit to Southend in the chance of seeing a juvenile Med Gull, in past years they have turned up quite early, sometimes in numbers.

With a peak high tide around 5.35am, I was down there just after hoping that the tide may have pushed them up on the beach.
Armed with some bread it proved so and worked out quite well, the only downside was the dark skies for photos but nonetheless I still saw 2 juveniles so all good.

Both were loosely associating with each other along with 5 other more mature Med Gulls in a large flock of Black Headed Gulls.

Also had a look along the beach for any Sanderling just in case but suspect it’s still a bit early yet.

Sand Martins

I have been coming across Sand Martins, up to 200 of them in the last week out on Cooling Marshes, Kent.

Good to see a great many juveniles amongst them, as you will see they have taken a shine to the entrance road and adjacent reed beds to rest up. First seen on the 14th, the flock is still present this week.

Unusual to see them on the road in numbers, I suspect it is a good place for resting and dust bathing, it also offers good all round vision against approaching predators.

Little Ringed Plover

Whilst surveying recently, one of the birds that I have come across is breeding Little Ringed Plover.

They do nest in some of the most unlikely positions and habitats that you could imagine, during the surveys nests/territories were marked as they are Schedule 1 to avoid disturbance, exclusion areas were then placed around them.

Below is a section of photos.

This adult was keeping an eye on some large Gulls nearby

This year so far to date, (fingers crossed) 4 juveniles have come down on fledging from the sites that I monitor and luckily all were spotted and rescued.

The first one, at Battersea Power Station, I think did not fledge but may have been blown off the nest site by those very strong winds and bad weather we had in early June. It was found by site staff and was then caught and returned to an elevated area especially designed for them up on the Power Station itself.

It was a lucky bird as it was not seen until the following morning after checking the cameras, it meant that it likely spent the night at ground level or it managed to get itself to an elevated position off the ground. Foxes obviously are present on site so it was a fortunate bird.

2 of the remaining 3 were located by the public, retrieved by the RSPCA and then taken to the South Essex Wildlife Hospital, I cannot praise them enough for the work that they do.

Both of these juveniles came from sites which  are not disclosed publicly, although I daresay that local people are well aware of them.

The last was a juvenile at Parliament, breeding there for the first time ever; the pair have fledged 3 juveniles of which one had grounded.

When I arrived I found the bird on a post where it had come to the attention of the local Crows and Magpies, I also suspected it may have been down for a couple of days unnoticed as it looked weak and underfed.

Catching it proved relatively easy compared to some, having a closer look confirmed first thoughts; it was weak, little fight or attitude in it at all.

I decided then to take it to the Wildlife Hospital where it was checked over, it was then fed and given a few days to recover.

All 3 of the juveniles, as you will see from the photo, were put in together in an aviary to recover as they all came in around the same time.

As all 3 obviously looked similar, each juvenile was given a coloured cable tie to make sure it went back to their respective site, this was then removed prior to release.

The release back went well and consequent visits to each site including Battersea have shown that the broods are complete, all are back with their parents and siblings.

Busy Bee

This is the first chance I have had to blog of late, surveys, watching briefs and Peregrine related monitoring of the sites I keep an eye on, has kept me very busy over the past few weeks or so.

It is a far cry from the hours I once put in for Steelfixing though, although that work was enjoyable and satisfying at times, it was hard graft; the bird work however is very rewarding and physically far less demanding.

The Falcon at Parliament - pity about the light

The Peregrines that I monitor this year(more on this on the next post) to date are having a good year again, my main monitoring sites all have chicks, one site has only produced a single eyass this year, but for size it is the biggest I have seen on social media.

Checking on Friday (13th) showed a chick over 3 weeks old, perhaps a day or 2 older, they would have to have laid relatively early for it to be this size already.

One of my other main sites, which produced only my 2nd clutch of 5 eggs to date and my first in London, have hatched 4 of the 5 successfully. These are on CCTV (not public) and have proved fascinating to watch, as much as you think you know, there is always something new to learn.

Thursday (19th) is ringing day for 2 of the sites, green rings with white numerals will again be going on as per last year.

In regard to surveys and watching briefs, I have been out on the North Kent Marshes mostly; it’s no secret that I love the wildness of the place and the birds that it attracts.

Highlights have been good numbers of migrants moving through, including 45 summer plumed Grey Plover in a single flock, also summer plumed Bar Tailed Godwit and Dunlin on a number of days. All are cracking looking birds which I rarely see in their breeding finery, usually associating them with the cold of the winter months.

On the Raptor front, female Merlin, Marsh Harrier, Common Buzzard and Hobby have been the highlights.

Local Listing

So far this year locally, the birding has been good in terms of spring migrants; Rainham in particular has delivered pretty well.
Of late, when I have had time, I have put in some early morning visits that have proved very productive.

The best birds so far for me at Rainham, other than the unfortunate deceased Razorbill, were probably the combination of Red breasted Merganser, Knot and Bar Tailed Godwit in Aveley Bay found by Paul.
The Mergs were likely the hardest of the trio to catch up with; I can probably count on one hand how many I have seen at Rainham over the years.
A good bird that I did not get to see was the Stone Curlew; however you can’t see them all so quite happy with proceedings so far.

The fact that last year I finished the year on 122 and this year am already up to 118, speaks for itself, hopefully a sign of some more good birds to come on the Reserve.

Ingrebourne Valley has also got off to a good start with 89 species, to date the best birds I suppose would rank as Greenshank, Mandarin Duck, Grasshopper Warbler and Bearded Tit for me.

Red Kite has eluded me, as it has at the other patches, the Valley has seen 5 of these cracking raptors go through this year.

The viewing area is looking good and as long as the river doesn’t burst its banks again, the mud that is showing may well attract more waders.

Grasshopper Warbler - Ingrebourne Valley

Barking is a relatively small patch that I cover but nonetheless still provides some good birds at the Outfall or on the Thames Water site.

The Barn Owls continue to hold on despite massive works and changes to the site which is great news, it just goes to show how site faithful they are.

One of the highlights recently other than the birding has been a regular Harbour Seal; I suspect it is there mainly due to the presence of the fish which feed at the Outfall. Whatever the reason it is a welcome sight to see one this far up the Thames.

The list goes well on 69 species for the year, surprisingly not one Hirundine has been seen but it is early days yet.
