Perhaps dazed Heron

It must be a consequence of the haze for the very sensitive Striated Heron to fly in right in front of me, striding the length of the branch as if it was alone.  This is one bird that takes off even at the slightest perceived human presence.  So it's a bonus to have it so close by, and off from its usual river bank haunt.

Finally it was ready to take off.
