This morning I spotted a Peregrine, adult and probably a male, at 
Kenilworth Park just inside the "wild" section past the barrier, perched 
and scanning the flats for prey. On me he turned no less baleful an eye. 
The resident Kestrel had apparently relinquished overlordship to his 
more fearsome confrere and was nowhere to be seen. A lone Robin sought 
to land in the same tree but spotting the falcon, thought better of it 
and nimbly executed a mid-course correction. A passing flock of 
Starlings proved a greater temptation and the Peregrine chased after 
them. The flock immediately morphed into characteristic tight ball 
formation, their instinctive counter to the falcon's strategy of 
singling out an individual, as they zoomed up-river with the Peregrine 
in pursuit.

Other species on site were few:
Canada Goose 0 (!)
Crows, mostly Fish  70
E. Bluebird 3
A. Robin  20
N. Mockingbird 2
C. Waxwing  80 (but ~200 last week)
Song Sparrow 5
