One more to add to the growing collection of Bronte Harbour grebe pics. Too bad about the boat reflections in the background, but some days it is difficult to find a good vantage point. Still provides lots of enjoyable moments though.

And now for the egg questions...A couple of weeks ago it seemed there were 5 eggs in the nest. In the photo below I count 9. Those, plus the 2 hatched chicks makes for a brood of 11 -- somewhat larger than the 3-6 eggs that iBird suggests. could it be that the other local grebe is dumping eggs into this nest, or could this hen be laying more eggs over time? Anyone know the probability of these eggs hatching successfully? Does the difference in egg colour suggest different potential for successful hatching?

Thanks and take care, CK Nikonian in Ontario, Canada
Very creditable CK, considering the equipment - all of which I've owned at one time. I notice from the shot of the eggs though that it works better at f12.6 than at f8. I've heard that other grebes have tried to lay eggs in the nest, but I've never seen it. I have no idea how this affects the probability of more eggs hatching.

Thanks for taking the time to comment everyone.
Dave, I'm finding the 2x +300f/4 works better with the 7100 than with the D80. Not surprising really given the higher pixel count and the fact that the 7100 auto focus works well at f/8. I was going to trade the 2x in and get a 1.4, but think I'll keep it now (and maybe still get the 1.4 down the road a bit).
Yeah, Jim, the 12.6 shot of the eggs looks a bit sharper than the f/8 shot of the birds. I think I'll try playing around with the fine tuning of the autofocus today and see if that changes anything. I also think I may have gone a bit too heavy with the black levels or contrast -- the cheek of the adult bird seems a bit "muddy" to me now, with the shadowed edges of the feathers a tad to dark.
I was down at the nest yesterday morning in the rain just to see if there were any other eggs that hatched. Only 2 chicks were visible and they are getting pretty big these days, so the nest was looking a bit crowded.
