The sleek Lizard

While waiting for the target bird, guess who would come around but one of the oldest residents, the Monitor Lizard.  It came or rather allowed the stream water to carry it along from upstream, then slithered up the bank.  Bulky as it might look, it climbed effortlessly and smoothly out of the water, and in seconds had disappeared into its hole.  It looked like the hind legs were the powerful ones, making wide strides.
