Tuesday evening CL pits initially i thought it was quiet distant cuckoo calling , single great crested grebe chick , and another brood of grey-lag geese gosling's X 6. Very few hurrindines over the water , but on reaching the gate north causeway a drake garganey was sat on the west shore of main pit ,and some proper record shots ensued on very limited battery life . Sorry. That was at 8:00 pm , moving down to the next gate on west shore lost the bird completely and after 10 mins scanning moved on. Saw only 1 redshank which was usual. South causeway 8:30 pm hobby catching insects brilliant views . 9:10 pm garganey relocated on east shore main pit.
