Not sure about HBW's "mainly crepuscular and nocturnal but sometimes
active on overcast days". While this applies obviously for all Ixobrychus
species, in my own experience (having observed all the world's Ixobrychus
species but Schrenck's), YB is the easiest to see out in the open in the
middle of the day.
