Banders & Birders,
Our final weekend of banding brought the late October influx of
sparrows....two weeks late. This weekend, particularly Saturday, was one of
records. This is only the third year (of six) that we've stayed open after
November 15, so such late records as the Hermit Thrushes (one each day),
Eastern Phoebes (2 on Saturday), Winter Wrens (3 on Saturday), American
Robins (4 on Saturday), and Swamp Sparrows (2 on Saturday) were probably not
particularly late. On Saturday, about 1000 American Robins passed along the
beach and over the nets, but only 4 were captured! Not much in the way of
wild food crop in our area this year. But, the Gray Catbird on Saturday and
the Brown Thrashers (1 each day!) were definitely late. The sparrow influx
also brought us record numbers of Song Sparrows (10 on Saturday),
White-throated Sparrows (26 on Saturday), and Fox Sparrows with 6 on
Saturday and 7 on Sunday, and brought our numbers of American Tree Sparrows
into a more normal range. We caught only a very small portion of the
White-throated Sparrows that were moving along the beach on Saturday and to
a lesser extent on Sunday. Our previous record YEAR for Fox Sparrows was 7,
so the 7 on Sunday was an excellent number. Our first (and only) Dark-eyed
Juncos of the season were caught on Saturday, which is more than a month
later than usual.
Saturday's 84 birds was a record for us for any day in November (81 was
previous record) and the weekend's total of 137 beat the previous late
November (16-30) period's record of 23 set in 2000.
On Sunday, our last day, we added a new species banded at the passerine
station, though not new for the Observatory. A Red-tailed Hawk somehow got
caught in one of our 30mm mesh passerine nets! Surprisingly, neither the
net nor the bander (me) was damaged in the process. We had to take this
bird to the raptor banding station to be weighed, since we didn't have a
container to hold it safely during this part of data collection.
Photo highlights will be posted on the HBMO website (www.hbmo.org) in the
coming week, and will include photos of a dark morph (Harlan's
intergrade???) Red-tailed Hawk caught at the raptor station on Saturday
(some photos already posted). I will post a brief summary of our fall
season within the coming week, which extended from mid-July through
mid-November. This will cover numbers banded only, and cannot include
interesting information on our diverse studies ranging from age/sex ratios
of hummingbirds, stopover ecology information, and data on our newly
initiated directional tendency study. Some of this will be published in the
more extensive summary in the journal of the Ontario Bird Banders
Association, while some will be published in various ornithological journals
in the future.

Holiday Beach Migration Observatory (HBMO) is an organization devoted to
monitoring migration at the Holiday Beach Conservation Area, Essex Co.,
Ontario, administered by the Essex Region Conservation Authority. In
addition to a hawk-watch/passerine count that has been in operation since
1974, HBMO operates three banding stations, two for raptors (since 1987) and
one for passerines and hummingbirds (since 1997). The Holiday Beach
Conservation Area was designated an Important Bird Area by Conservation
International in 2000.
