A Heron's dismal outing

I love to watch, stealthily of course, the Striated or Little Heron trying to fish but lately it's being rather sad doing so, simply knowing that it's a huge effort for this bird as the river has been over-fished, by who else but man!  Using mist-like nets, these men frequently scooped away all sorts of fish.  Varying sizes and types of fish were once easy to spot in this river but sadly, it's no longer so.

This Heron eventually left this spot without catching anything.  Hopefully it had better luck elsewhere.

Turning to the right didn't yield anything either for this fisher of bird.
