The 24-hour Westport Christmas Bird Count is scheduled Sunday, Dec. 18, and participants will be looking for both the unusual and commonplace.

The 65th annual count begins and ends at midnight, but organizers said most birders will be counting during Sunday's daylight hours -- rain, snow or shine.

The Westport count is one of 17 planned across Connecticut and will contribute to the National Audubon Society's 112th annual Christmas Bird Count.

The Westport count includes territory outside the town's boundaries. The area includes a 15-mile radius around the twin bridges on Route 57 in Westport, according to Mardi Dickinson, the count's captain and compiler.

The intent is to locate, identify, and count all birds found within that area, she said.

The count is open to birders of all experience levels, from people who feed pigeons to trained ornithologists, and inexperienced counters typically are paired with experienced ones, Dickinson said in a news release.

Teams of observers will canvass many places where birds or certain types of birds are known to frequent, identifying and counting each species they see.
