Diver sp.

Had a lovely Sunday afternoon in Pembrokeshire at the weekend. I wonder where the BBRC draws the line with a recently split crypto-tick when it shows only 50% of the features that were thought to be failsafe before we all started looking at Black-throats.


Quite small (though not as small as some would have you believe), thin billed, pale nape and lacking a white flank patch...


... also lacking a chinstrap, and anything like the vent-strap of the North Yorks bird (is that a thin brownish strap beyond the foot?).

I'm assuming the overlap zone between pacifica and viridigularis isn't swarming with hybrids.
