Battersea Power Station

 

April 9th



Hi, a rather cold morning, overcast in the morning which seemed to affect bird numbers, certainly some of the regular species were a lot harder to find, 5 degrees putting a dampener on early breeding activity.

Peregrines

The female at 14 is still present, I would have expected her to have been replaced a good while ago, it seems it's not going to happen again for this breeding season, although it still could. Last successful breeding was 2021 with 3 juveniles fledged, however she has been a great female producing 22 juveniles since 2013, a superb effort, time marches on though and age has caught up.

It's not for want of trying to breed on the Tiercel's part, but the Falcon is no longer receptive to copulation as you will see from the photos.

As I have mentioned before, it's a shame with both having accepted the new nest box position totally.

                                                       Tiercel - still trying to breed

Elsewhere, the male Black Redstart was singing initially, but likely then thought better of it with the cold temperatures, I didn't see him at all.

The Gardens aloft were unusually quiet also which I would put down to the cold, hardly any birds seen up there.

Birds that were very apparent were Grey Wagtails, paired up, we again have 2 pairs along with a pair of Pied Wagtail, all were investigating the River Wall where breeding has taken place every year.

 

Parliament March 20th

 

Good news for Parliament, she has laid eggs and is incubating after visiting on Thursday March 20th.

With sunny and warm weather, it was an opportunity not to be missed arriving on the Thursday around 6.45a.m.

Throughout the morning, she was in and out of the nest box, the Tiercel was hunting and took a turn at incubating whilst she fed.

Also present still and possibly going to assist in breeding is ABB, one of last year’s males, he was not only hunting but also seeing off Crows, Herring and Lesser Black Backed Gulls.

Watching the 2 Tiercels together, no aggression is being shown by 'Dad' so it looks as if he doesn’t see his offspring as a threat, hopefully he will be a help and not a hindrance.

I have seen this before at Battersea Power Station in 2019, and it din’t end well, the 1st year bird clumsily ‘spiking’ 3 of the 4 chicks offspring assisting in the feeding.

Battersea Power Station

Sunday March 16th



I visited last Sunday, fantastic bright weather but exceptionally cold at only 1 above, I certainly seem to feel it more these days.
However, arriving at 6.00a.m with a perfect sunrise shortly after, helped with the cold as I set about locating the Peregrines.

I immediately found the Falcon, she was already on prey feeding aloft, as I watched feathers from plucking started to drift down. Retrieving some of these showed the prey to be a Woodcock, these have been recorded as prey before at the Power Station, all have been taken nocturnally.

As the morning moved on, the Peregrines became very active clearing the Crows that invaded the Power Station airspace.

It is still the same female, at 14 now unable to lay an egg and breed, it will only be a matter of time before she is displaced….

                                                           Large Gulls also got treatment

2 male Grey Wagtails were sub-singing along the River Wall in preparation for breeding, checking earlier showed that the winter roost, which held 12-14 birds, has dispersed it seems. Also on the river was a Common Sandpiper, quite distant upriver and I was unable to get a photo of this.

Visually checked some of the nest boxes, not much activity with the cold weather but it will come, hopefully more uptake this year. However, Goldfinches are starting to make themselves known with a couple of pairs nest site prospecting in the trees in the Northern Park.

The Power Station hotspot and my now go to place for the Black Redstarts continues to be the East Side Gardens aloft. I found 2 immediately together at the southern end, however looking at the male, it was a 1st year bird with a wing bar and not the full adult male seen previously.

Good to see, obviously it means that we have had 3 birds minimum at the Power Station recently, it's no surprise that they like this particular area, it gets the sun first, has warm blowers and abounds with insects, this is shown by the number of Garden Spiders present when it gets warmer.

The feeders held at least 6 Goldfinch, but I also again heard the male Blackcap sub singing, try as I might I only got fleeting views of it, very elusive in all the trees and shrubbery.

I finished the morning on 29 species, hope to go better in the coming months as summer migrants arrive.

 

Beckton Latest - March

The warm weather is just starting to kick in after the cold spell, its pushed the Kestrel pair towards the nest box more, both are now becoming very territorial around it.

As usual the Crows are a bit of a pain for the Kestrels, mob handed, the Crows I would suspect are all unpaired likely 1st winter birds.

The Kestrel male looks different to last year, no grey head as per last year’s male so possibly a younger bird.

The Common Buzzard pair continue to be fairly elusive, despite their size, like the Kestrels often attracting attention from the Corvid mob, however these just seem to go on about their business more or less ignoring them.

I have marked 2 big nests which I think they will use, it would be good to see them successful again.

No Blackcaps as yet but plenty of Chiffchaffs now calling, hopefully a Wheatear or a Sand Martin soon.

Abberton Reservoir

March 5th



A cold but very bright morning on Wednesday on our day out, as with most of this week, glorious sunshine from the word go.

In a 2-hour watch on both causeways I recorded a good number of species, most of the winter specialists like Gooseander and Goldeneye, I didn’t go further afield so would have likely added others that I knew were present.

Top of the show will undoubtedly go to the 2 Slavonian Grebes that are wintering, I have seen them in the past elsewhere but mostly fairly distant, these views were quite incredible.

I would presume a pair, both still in winter plumage, one of them was offering the other a piece of weed swimming around the other, no doubt the sun/growing warmth bringing on early breeding display.

Watched these for quite a while, also seen were Green Sandpiper, Great Egret, 3 Redshank and a distant Common Buzzard amongst many others.

No sign of any Spoonbills/Cattle Egrets as yet, but Grey Heron colony in full flow.
