[EBB Sightings] Caspian Tern Heather Farm

This morning just before 8 AM I saw a Caspian Tern cruising back and forth 
over the large natural pond in Heather Farm Park in Walnut Creek.  This is a 
nearly annual sighting and I was recently thinking that I haven't seen one 
here yet this year.  Admittedly, I have not been very regular in the park 
lately.

Also seen was a juvenile Green Heron.  Later, two Green Herons were flying 
southeast along the creek separating the south ball fields and the houses to 
the east.  One perched on a power pole before continuing southeast, the 
other returned to the natural pond.  I have sometimes found their nests 
around the pond, but this year I was unsuccessful.

A Black-headed Grosbeak was heard along the road between the equestrian 
center parking lot and the Seven Hills School gate.  At first I thought it 
was a woodpecker "pick", then it sang briefly before flying away.
