Certainly as far as Ducks go, Presa Centenario was at its best today. On an evening stroll (I only got less than a quarter of the way around the reservoir), I clocked up an incredible 13 species. This count didn't include the Redhead and Fulvous-Whistling Ducks from last Friday, so there could well be 15 different types of ducks currently on Centenario - top stuff.
Here's today's tally:
Northern Shoveler - several thousand (most at the south end of the lake where i didn't reach)
Northern Pintail - 20 (but many uncounted at south end of lake)
Mexican Duck - 70+ (in a flock near the 'dog pen')
Green-winged Teal - 200+ in the shallows
Blue-winged Teal - 150+ in the shallows
Cinnamon Teal - 1 adult male near the dam, my first sighting here
Ring-necked Duck - the 300 strong flock remains
Lesser Scaup - 3 males near the dam
Ruddy Duck - several hundred
Canvasback - 3 within the Ring-necked Duck flock
Gadwall - 1 adult male near the 'dog pen'
American Wigeon - 3 near the 'dog pen'
BUFFLEHEAD - 3 adults at the dog pen, a new record for Queretaro.
Throw in 500 Eared Grebes and hordes of American Coot, and you've got a fairly decent selection of waterbirds there.
Here's some of the better pics (and a record shot of the BUFFLEHEADS
