[EBB Sightings] Grasshopper Sparrows -- Wildcat Canyon

My wife and I took a mid-afternoon Mothers' Day hike in Wildcat Canyon  
RP: down Rifle Range Rd Trail and into the grasslands to the north.  
Grasshopper Sparrows were as numerous as I've ever seen or heard them  
there. We saw four singing males and heard perhaps an equal number  
that remained invisible -- all within perhaps an hour and a half. Two  
of the songs included high jumbled notes following what I think of as  
the usual "click-bzzzzz". Also notable among forty or so species for  
the afternoon were several Lazuli Buntings and W. Bluebirds, and a  
lone Lark Sparrow.
