I had an hour to "waste" at lunch time today so I went to Wright Park. 
When I arrived some 60 Goldfinch were busily lunching on weed seeds in 
the meadow at the head of the trail, while a number of recent fledglings 
were begging and jiggling new wings from the branches of shrubs and 
saplings.

Peace turned to chaos as low from the east a Harrier jumped the 
lunchers, zooming about among the shrubs scattering the Golden crowd 
like crumbs in an gale.  No catch was made.

An hour later, returning to the car I again found the chattering 
finches, paused to listen, when a Merlin exploded at full speed into the 
flock, darting, dashing, swerving, jinking ... always with three or four 
panicking golden darts right in striking distance scurrying for their 
lives while the rest flew in all directions like sparkler sparks on the 
4th.  Moments later, in some grasses between two shrubs, the Merlin was 
munching on its lunch.
