Did it or did it not

 In view of the height of the tree and nest, and that the nest has been reused more than once, it was expected that the chick would grow safely to fledgling, providing some delightful moments of its movements and growth. 

First sightings - tiny, white, active, alert, sharp, ability to sense being watched even from a distance, possibly at least 2 weeks old at this stage.

7 days later, ie 3 weeks old.

Another 7 days later, 4 weeks old.

12 days later, almost 6 weeks old.

7 days later, 7 weeks old.  

By comparison of past nesting report, this one looked terribly small for a 7 week-old.

The female parent as usual was keeping a close watch over it, and constantly calling out to her mate, for feeding or perhaps watch rotation.

I returned after being away for more than 10 days, hurried to the nest, full of anticipation as the chick should be almost 9 weeks old now, possibly playing outside its nest.  

However, all I found was an empty nest, and distant calls, perhaps of the adults, perhaps the juvenile (which were difficult to discern without sighting) in the vicinity.

Past reported sightings recorded a CHE juvenile taking flights around its nest and close-by at 9-10 weeks.

But it was not so for this one.

All in all, I've had almost 2 months to observe this chick.  

So did it survive, did it fledge whilst I was away, are still questions on my mind as I've still not sighted the juvenile even after repeated visits to the nest for more than a month now after my last sighting.
