A bad case of ‘telescope eye’ and the DDDs

Staines Reservoir, South Basin

The Staines Reservoirs are one of the best birding locations in London. The site is also a bogey location for me; something good at Staines probably won’t be there, or be visible when I arrive. Matters aren’t helped by it being about as far away from where I live as you can possibly get whilst still being in London.

The bisecting causeway

I was drawn there today with the hope of seeing some terns. Anything other than Common Tern would be a year tick at least for me, and I thought I might have a chance with Arctic Tern or even a Black Tern. I had also heard that some rather late Black-necked Grebe were there this morning, which would also have been a year tick.

I scanned the vast expanse of water, first with my bins and then switched to ‘scope, slowly working my way around the fringes, but the only grebes were Great-crested Grebe, and the only terns were Common Tern (although both were here in large numbers).

I don’t know whether other birders have noticed, but using a spotting ‘scope for long periods of time screws you up. Having the vision of one eye vastly magnified for long periods of time, and the vision of the other eye completely restricted; closed to aid focus in the other eye. When I put the scope down, a weird asymmetrical sensation occurs.

I spent a bit of time watching Common Tern on the rafts with all the Black-Headed Gulls.

One pair were getting ‘close’ to each other if ya know what I mean…

Common Tern (Sterna hirundo)

At first, the male didn’t really look like he knew what to do and he just stood on the female’s back for about minute:

But shortly afterwards things seemed to get … er… going.

Whilst interesting, it was another ‘day of disappointing dipping’ for me, or ‘DDD’ as I like to call it.
