You don't have to be an ornithologist to help with bird
banding. Last fall, I volunteered at
Prince Edward Point Bird Observatory. This
is a volunteer-run research station located on the eastern tip of Prince Edward
County where it extends south into Lake Ontario. It's the first landfall for
migrating birds coming across from the south in the spring and the last for
those heading to warmer climes each fall.
As well as people who recognize the difference between a hermit
thrush and a Swainson's thrush, the observatory needs willing hands to put up
the nets at dawn, take them down six hours later, hold the collecting bags, and
record information provided by the experts. It's
easy to do the recording for inexperienced banders who take five minutes to process a
bird, but some people know the species so well they can identify, sex, age, and
weigh a bird in less than a minute. New scribes need to focus when volunteers
such as this man from the United Kingdom examine a gray-cheeked thrush.

Experienced volunteers identify, sex, age, and weigh each bird before banding it. |
While volunteers are watching, they
learn a lot about familiar species. Note the orangey red on this golden-crowned
kinglet, for example. This colouring differentiates it from the ruby-crowned
kinglet, which has red without any yellow.

Banders constantly check
their bird books as even something as minor as white around the eye can
differentiate between this Nashville warbler and a similar species.
Fortunately, the head bander is always around to double-check identifications.

Interestingly, it isn't just
humans who look out for migrating birds. This sharp-shinned hawk got caught in
a net while chasing a smaller bird.

This barred owl was sitting
on a tree in the net lanes where they trap saw-whet owls in the evening. To
protect the saw-whets, banders trapped this female, banded her, and then
relocated her. Take a look at that beak. No wonder people were so cautious handling
the two-year-old.

Are you still wondering how to tell a Swainson's thrush from
a hermit thrush? The Swainson's has a brown tail. The hermit's tail is red.
They both have speckled breasts, as do all members of the thrush family,
including the robin. Learn more by volunteering at or
visiting your local banding station.

Like all members of the thrush family, this Swainson's thrush has a speckled breast. |
