This photo shows it lacks the yellow
orbital ring that is present in all ages of Semipalmated Plover. The
facial markings are wider on Common Ringed Plover. The line on the
lores between the eye and the bill is wider and meets the bill at
the gape rather than being narrower and above the gape on
Semipalmated Plover. The white flare above the eye is larger than on
Semipalmated Plover. |

This photo and the next show the pattern
of the webbing between the toes, which is typical of Common Ringed
Plover: NO webbing between the middle toe and the inner toe and very
slight webbing between the middle and outer toe. Semipalmated Plover
has visible webbing between all three toes. |

Quebec
Common Ringed Plover on 17 and 18 August 2016 |
|
On 17 and 18 August 2016, an adult
Common Ringed Plover was just west of Trois Rivieres in Quebec.
Given the extreme rarity of this species, one wonders if it is the
same bird. It was not seen on 19th and our Toronto bird was
discovered on 20th. Thanks to Jacques Bouvier, Brian Morin and
Michel Gosselin for alerting us to the Quebec bird. Several photos
are here: |
