Yes, the rapidity of tooting in Pygmies is much slower than a Saw-whet:
Saw-whets rate is about 2 toots/second in full bore; whereas, a Pygmy is
lucky to get to about 1 toot/5-10 seconds. Pygmies can call at all times
of the year - I have heard them at dawn in October in Bowron Lakes P.P. -
whereas Saw-whets tooting is restricted to the spring courtship season.
