2004
By Benjamin P.
Burtt TOPICS: The Birds that migrate in September and
early October. The Feeder
Survey Begins in Two Weeks.
Discussion of what it is, how you can help and Complete Instructions
for you to follow. Introduction This column is
divided into two sections here Section 1 contains a copy of the column as it appeared
in the newspaper on the date above. Section 2 contains
additional information on the Feeder
Survey that starts October 3, what it
is is and how you can help me with this scientific project. Detailed
instructions are provided for your participation. SECTION
1: HERE IS A COPY OF THE COLUMN THAT APPEARED IN THE POST STANDARD ON
SEPTEMBER 19, 2004 BIRD
COLUMN FOR September 19, 2004 By Benjamin P. BurttMIGRATION
NEWS Many birds that are just here during the summer have gone
south already. They slip away and we do not notice. These include chimney
swifts, nighthawks and hummingbirds. During September, warblers are going through from their
nesting grounds further north and we will not see them again until spring. Migrating thrushes will be conspicuous in the coming
weeks. The veery, which breeds here as well as to the north, left in
mid-September. All the other thrushes, however, will now gradually pass
through in numbers. Each individual will be here for a day or two and will be
replaced by others as it moves southward a bit each day. Wood thrushes are
next, but by mid-October all of them will have passed through our yards. Also coming through from the north are the grey-cheeked
thrush and the Swainson's thrush. They will be seen for about three more
weeks. The bluebird, hermit thrush and the robin continue their
migration until mid-November. As for flycatchers, all will be in gone in a few days
except the phoebe. By the end of October it too will be gone. Some birds feed on the ground during migration and stop
off in our yards where we can easily see them. The dark-eyed juncos and the
white-throated and white-crowned sparrows are for many of us the most
exciting migrants in the fall season. These species are just beginning to show up. Flocks in the
back yard brighten the October days, but they will all be gone by the end of
that month. STAY HERE FOR THE WINTERWhile most white throated sparrows and juncos go further
south, a few remain in Central New York through the winter. Another sparrow
that spends the winter here is the tree sparrow. It breeds farther north than
does the white-throat or junco. It nests in the Arctic beyond the trees, but
spends the winter in the Northern United States. It will be along in a few
weeks.
CAPTION: Migrating Sparrows. The two most conspicuous
sparrows that will be moving through are the white-throated sparrow, top, and
the white-crowned sparrow, bottom, shown in this painting from Roger Tory
Petersons "Field Guide to Birds of Eastern and Central North
America." Both birds have stripes on the crown, an unstreaked breast as
adults, but the white-crowned sparrow is a grayer bird. The white-crowned has
a pink bill instead of a dark one and it lacks the white throat patch. The
white-throated sparrow also has a yellow spot in front on the eye.(Courtesy

2: A SPECIAL ANNOUNCEMENT ABOUT THE
OCTOBER FEEDER SURVEY The October feeder survey starts two weeks from today on
Sunday October 3 and continues through the following Saturday. I hope that you can help me with this. This is a scientific project that I have been operating
since 1959 that utilizes readers of this column who observe the birds in
their yard and report the numbers and species to me. It is a lot of fun and
if you haven't participated before, the following paragraphs describe what it
is and how you can help out. Your observations will help me find out what birds are
visiting our yards and feeders throughout the winter. When the results are
printed, you can compare the number and types of birds at your feeder with
other feeders in the area. I will be
able to compare this years results to earlier years. Participation in this fun project is open to all readers
of this column who live in Central and Upstate New York State. Here is how I
define the limits of that area. The northern boundary is the St. Lawrence River and Lake
Ontario west to Rochester. From there the boundary goes south to Elmira and
Binghamton. From Binghamton the line goes north east along Interstate 88 to
Albany and then north on Interstate 87 to the border with Canada. Thus it includes all of the Adirondacks and the Finger
Lakes regions. For those of you familiar with the reporting regions of
the former Federation of NY State Bird clubs, it includes all of Regions 2
through 7 and part of 8 ( The
Federation has a new name, The New York State Ornithological Association ). History of this projectThis feeder survey was started in the winter of 1958-59, and data have been gathered every
year since then. The idea was suggested by the late Dr. Francis Scheider. So
this is the start of the 45th year of this project. In 1970, a feeder survey was initiated in England. In
1976, one was started in Ontario, Canada, by the Long Point Observatory. The
Cornell Laboratory of Ornithology began a survey for the whole United States
in 1987. This is
what you do. Starting on the
first Sunday of the designated month and continuing through Saturday, when you have a few minutes, look out the
window at the feeders in the yard, and record the number and species of all
birds that you can see from the house at that moment. These birds can be at the feeder or
anywhere in sight. Those flying by can be counted if you are sure of the
identification. You can record birds that you see when you are outside as
long as you are looking from a point right near the house. Birds seen on
hikes nearby are not to be included in the list. To avoid counting the same bird more than once, write down
the maximum number of a given species that you see at one time. This way, you know that there are at least
that many birds visiting your yard. Later that day or on another day during the week, check
the yard again and write down the number of each species that is visible at
one time during that period. Watch as
often as you like and keep these lists until the end of the week. You don't
have to watch every day, but any day Sunday through Saturday can be included. Then, summarize your observations by preparing a single
list for me that shows the name of each species seen and the largest number
of birds of that species sighted at any one time during the week. For
example, if you see a total of 42 house sparrows this week, but never more
than nine at a time, nine is what you put on the list that you send in. There may be more than nine house sparrows around your
yard, but we are certain that there are at least nine. We conduct a survey for a week starting the first Sunday
of the month from October through May.
Through these surveys we see how the population of different species
changes throughout the winter. We can
also pick out long-term changes in the population of some species over the
years. Preparing
the list. There are several things you can do to make the tabulation
easier for me. First, it is a big
help if each list has the birds in the same order. If you can, please use
what is called "check-list" order. It is the order the birds are listed in your field guide and
the order I use when I publish the list of birds seen on a survey. The second way you can help is to put each species on a
separate line with the number of birds first and followed by the name of the species. Please write the total number of species at the top of
your list. Unusual birds. If you list a bird that is
unusual in this part of the country or should not be here at the time of the
survey, or closely resembles a species common in our area, please write a note
describing the field marks you observed and how you made your decision. Sending in the ReportsAt the end of the week, put your final list on a postcard
or in a letter and send it to the address below. You can use EMAIL if you
wish. If you do use Email, please give your name and address so I will know
where your observations were made. PLEASE send your report by Monday right after the survey
so that I can get the tabulation done in time to write up the results by the
following Saturday. Send your feeder survey report to either of the following addressesBy Regular Mail: Ben Burtt, PO Box 4915, Stars Magazine,
Syracuse, NY 13221. By E-Mail: Send to features@syracuse.com. Be sure to put
"For Ben Burtt" in the Subject Line. . How you
can read the Summary Report of the results. About 3 weeks after a particular survey week ends, when
the next survey starts, I will make
available on this web site a detailed discussion of "The Feeder Survey
Results" It will include the complete list of species, a discussion of
all the trends and unusual birds reported, as well as the longest and
shortest lists, etc. Click on COLUMNS and then the date of that column. A brief discussion and summary of the observations is
published in the newspaper on that same date, but there is not enough space
there for all of the details that are in the summary of the survey on this
web site. . |
