Eastern Towhee in Sioux Lookout

A rarity at any time of year in northern Ontario, this male Eastern Towhee has been visiting a feeder in Sioux Lookout in the Kenora District since November 20th. Many thanks to Marlie Squires for sharing the sighting.

In Longlac, Thunder Bay District, an even more unusual Spotted Towhee continues to visit the feeder where it was first seen on November 12th.

Join in the December 18th Marathon Christmas Bird Count

On December 18, volunteer naturalists will conduct Marathon's annual Christmas Bird Count (CBC). Birders of all skill levels are welcome to help count birds within a 12 km radius of town, which includes the communities of Heron Bay and Pic River. Some parties will range out into the bush on skis and snowshoes while others will stay close to their vehicles, counting birds along the roadsides.

Residents who maintain bird feeders will contribute by keeping a tally sheet of the species visiting their yards. All participants are encouraged to attend a fun and informal chili dinner at 5:30 pm during which bird numbers will be totaled and stories and photos will be shared.

    The CBC is the longest running Citizen Science survey in the world. Data collected by tens of thousands of participants throughout the Americas are used by scientists to help monitor our bird populations. In Canada, the counts are administered by Bird Studies Canada. CBC participants (other than children under 18 and those conducting back yard feeder watches) contribute to Bird Studies Canada a $5.00 fee to help offset the cost of administering the program (details here).

    Marathon Count Circle

    Marathon residents have participated in most years since 1973. Over all years a total of 85 species have been recorded but for each year the average is 25 and no two years are the same. While a handful of common species - Herring Gull, Common Raven, Black-capped Chickadee and European Starling - are seen every year, waterfowl, raptors and winter finches are less predictable. Each year turns up a few surprises. Bald Eagles are now commonly sighted in Marathon throughout the year but they only began appearing on the CBC in 1994 as the continental population rebounded following the implementation of restrictions on the use of organochlorine pesticides.

    Northern Cardinal, a very common species in the south, started appearing on our CBC in the late 1980s reflecting an ongoing northward expansion of its range.

    How to Get Involved
    • Those wishing to participate in this year's CBC should contact Martha Allen at 229-1319 immediately. Martha will assign each person to a team covering a particular section of the count circle. Those conducting feeder watches will be given a tally sheet for birds visiting their back yards.
    • In the morning, each bird counting team will assemble before heading out to count birds in their assigned areas.
    • (Optional) Bird counting teams will meet up with each other at noon at Rumours Coffee House & Deli in the Superior Place Mall (2 Ontario Street) to warm up and trade stories before heading back out for the afternoon.
    • Tally sheets should be dropped off at 8 Steedman Dr. around 5:30 pm. All are welcome to stay for a bowl of chili, a slide show and a draw for a prize donated by the Friends of Pukaskwa.

      Harlequin Duck at Pukaskwa National Park

      Parks Canada staff photographed a stunning male Harlequin Duck off the Manito Miikana peninsula in Pukaskwa National Park today. The bird was found swimming along a very exposed, steep rocky shore - typical wintering habitat for the species.

      The Harlequin Duck is considered rare in northern Ontario and 2011 has been a better than average year for sightings in the Thunder Bay District. This fall others have been seen on the Nipigon River (one on Oct 22), at the Thunder Cape Bird Observatory on the Sibley Peninsula (two on Oct 22) and in the Kam River in Thunder Bay (one on Nov 11).

      Harlequin Ducks have been sighted in the park a few times before.

      Park visitors should note that entrance gate is closed for the season. All access is on foot.

      December 10 update: We hiked in to the park and enjoyed watching the Harlequin Duck bobbing around in the surf.

      American Three-toed Woodpecker

      I heard this bird foraging deep in a stand of spruce from a distance of 50 m or so. It and a Hairy Woodpecker were today's additions to my 2011-12 north shore winter bird list.

      White-winged gulls at the Town of Marathon landfill

      Gull viewing conditions at the town landfill were better than usual today - the gates were open and several hundred gulls were present and cooperative. These birds have become habituated to the dump trucks, graders and bulldozers associated with the operation of the landfill. They slowly walked out of the path of my truck as I slowly drove, about 10 metres at a time, through the loafing flock. If I had been on foot, I wouldn't have been able to get closer than 100 metres or so without flushing them.

      Almost all were mature Herring Gulls.

      Usually two or three Glaucous Gulls overwinter in town. Iceland Gulls are less common. This sharp looking first cycle bird was the first we've seen this autumn.
