Help Needed
in BC to Monitor Pine-dependent Birds
17 December 2006
– In the Thompson Region of BC, particularly around Kamloops, the
Mountain Pine Beetle is having a catastrophic impact on Ponderosa Pine
forests. In the last 18 months alone, beetles have killed as much as 80
percent of mature Ponderosa Pine stands. This last year there was a
massive Ponderosa Pine seed crop produced in response to the die off,
but because of the pattern of Mountain Pine Beetle kill, there will be a
dearth of seed for many years to come. One of the bird species that
could be dramatically affected by the absence of a large seed crop is
the Pygmy Nuthatch Sitta pygmea, whose life history appears
closely linked to the availability of Ponderosa seed. Birds cache the
high-energy Ponderosa seeds in pine bark during the fall, which provides
them with a vital energy source to survive through the winter. It is
possible that Pygmy Nuthatch populations in areas of extensive pine kill
could decline dramatically in winter 2007-08. Ponderosa pine mortality
is beginning to increase in the Okanagan Valley as well, and it will be
important to track bird numbers there if the pine die-off continues.
Pygmy Nuthatches are regular visitors to feeders in winter, and Project
FeederWatch provides a methodological basis to monitor the situation. In
addition, the eBird and Christmas Bird Count programs will provide
important data to track any changes in distribution and abundance of
winter bird populations that exploit pine seeds as a key food resource.
This is an important time to encourage friends and local naturalists to
enroll in Project FeederWatch
– it could make the perfect Christmas gift. To participate in
Project FeederWatch, we ask that you first become members of Bird
Studies Canada (BSC), a national, non-profit research institute studying
birds and their habitats for conservation. For an annual $35.00
membership fee, participants receive the FeederWatch instruction
booklet, resource manual, data forms, a calendar, a poster of common
feeder birds, and BSC’s quarterly publication, BirdWatch Canada.
Members may also participate in other BSC programs, including the
Canadian Lakes Loon Survey and the Christmas Bird Count. To register,
fill out the online form
or call 888-448-2473. If you are already a BSC member and would like to
register for Project FeederWatch, please call our toll free number at
888-448-2473 ext. 210. For more information, please e-mail
pfw@bsc-eoc.org.
Call for Winter Raptor
Observations
13 December 2006
– To all winter birders in Ontario: Help is needed to collect
important information about Short-eared Owls and Bald Eagles over the
winter months. Bird Studies Canada (BSC) is now in the fourth year of a
wintering Short-eared Owl survey in Ontario. These owls, characterized
by a distinctive and erratic moth-like flight pattern, are listed as a
species of Special Concern in Canada’s Committee on the Status of
Endangered Wildlife. Large concentrations of these owls, however, are
observed during the winter months in southern Ontario. Little is known
about the species, and why numbers are declining. For more information
on Short-eared Owl monitoring

Through the
Southern Ontario Bald Eagle Monitoring Project, BSC tracks eagle nesting
success and productivity. To complement this research, winter
observations are of interest within the lower Great Lakes basin (from
the Ottawa valley through to the Bruce Peninsula). We would like to
identify potential winter roost sites and determine the number of eagles
wintering in this area. For more information on the Southern Ontario
Bald Eagle Monitoring project,
click here. If you see either of these raptors please take note
of the date and time of sighting, number of birds, age class
(adult/juvenile), habitat, geographic location, and activity.
Observations may be submitted by email to Jody Allair, Recruitment and
Outreach Coordinator at
raptor@bsc-eoc.org.
Marsh Monitoring Staff Attend
“State of the Lakes Ecosystem” Conference
10 November
2006
– Bird Studies Canada’s
Aquatic Surveys Scientist, Steve Timmermans, and Marsh Monitoring
Program Assistant Coordinator, Ryan Archer, attended the “State of the
Lakes Ecosystem” Conference (SOLEC) 2006 from 1 - 3 November in
Milwaukee, Wisconsin. SOLEC 2006 was the seventh biennial conference
wherein the governments of Canada and the United States assess and
report on the condition of the Great Lakes basin ecosystem.
The focus of this year’s conference was
chemical integrity; Day 1 of SOLEC focused on the state of the Great
Lakes based on indicator assessments, and Day 2 focused on the chemical
integrity of the Great Lakes as well as the indicators needed to assess
chemical integrity. Ryan and Steve attended several workshops
regarding the use of indicators for lake assessment during this three
day event. For more information about SOLEC 2006,
