My weekend’s birding began pretty poorly with very little of interest showing on the Patch. So, hearing about Black-throated Diver – found by Lol Bodini – on one of the Walthamstow Reservoirs gave me more than enough excuse to try and get a London tick after lunch. This really was an excellent find by Lol and we are always willing to put aside our friendly patch rivalry when rarities like this appear – the first in East London for a few years.
When I arrived at Walthamstow I was lucky to bump into Lol (not ‘literally’ as we actually stood next to each other at the urinals in the visitor centre, so ‘bumping’ would have been problematic) who gave me the gen. With a bird like a diver on a reservoir, the thought didn’t really enter my mind that I might miss it, so I didn’t even rush.
Lockwood Reservoir is a big body of water, but much smaller than the giants like William Girling and King George V further north in the sequence.

I was a little perturbed to find a birder who had been scanning for ten minutes with no success. I walked up along the east shore scanning the other shoreline in case it was tucked up against the side. I met two more local regulars coming the other way who passed on some more bad news; they had been watching the Diver (they even showed me some great back-of-camera shots) but then it had dived and hadn’t been seen again. That either meant it had drowned (pretty unlikely for a … err… diver), or that it had come up a little way off and flown before they had noticed. Dipping a diver that had been seen only a few minutes before now seemed likely and galling.
But then my knight in shining armour appeared in the form of Stuart Fisher (wearing more of a tracksuit than a suit of armour, to be honest), zooming around the reservoir also looking for the recently departed Diver. We met Lol again as well and agreed that our best, but slim chance was to check Banbury Reservoir up the road. The only glitch being that Banbury is locked and inaccessible. But this is where the local knowledge of Stu Fisher was absolutely golden. He knew a spot on a housing estate on a hill where a sliver of the the reservoir was visible. Slim chance, but this was our only chink of hope.
We schlepped up there with me carrying my scope and peered through gaps in blocks of flats to look at the water in the background. By absolute luck, there it was – a whopping great diver with white flashes on its sides. Stu spotted it first and I was almost incredulous, and then elated. I felt a bit creepy and intrusive standing in front of people’s houses and staring through a telescope through gaps between buildings.

On Sunday I went to Rainham Marshes to try and see the Bittern that has occasionally been showing to people viewing from the Ken Barrett hide. As I sat in the hide I chuckled to myself about my patch colleague’s experience in here the week before, humorously (and rather controversially) recalled on his blog.

The Bittern didn’t show, and nor did much else of interest from the hide so I couldn’t bring myself to follow Jono’s lead and sit in there for hours waiting.
The sea-wall of the Thames was much more productive. Almost as soon as I arrived in the morning, I spotted the Black-bellied Brent Goose floating down (and later back up) the Thames (here comes another distant phone-scope record shot).

Two days, and two London firsts under my belt. But the sea wall had more to offer. Good numbers of Dunlin and Avocet occasionally took flight and whirled around the sky when something disturbed them.

By something, I mean like the Marsh Harrier which came in off the Thames and swept low right passed me (sadly while my camera was packed away). Or like the Short-eared Owl which pounced on something right on the water’s edge before slowly flapping away low along the shoreline.

There were plenty of Meadow Pipit, as usual at Rainham, but I also saw and heard Rock Pipit moving up and down the shore. And occasionally a slightly different-sounding single call was heard (as I was able to hear both calls close by at roughly the same time, this is the first time I have been able to distinguish their calls in the field) and eventually a Water Pipit landed a little way off in front of me and fed in the grass – its white tail streaks showing clearly as it flew in and with a much paler breast than the Rock Pipits which also occasionally showed well.

Finally, I also managed to get a year tick in the form of a single Ringed Plover on the Aveley Bay shoreline. I say finally, but it was actually one of the first birds I set eyes on when I arrived, but I never promised to tell my stories chronologically.

And because I can’t bring myself to sign-off a blog post with a terrible phone-scoped record shot, here was my view for much of the day:
