What
is a yard bird?
I'm defining a yard
bird as a bird that is identifiable by sight or sound while you are within
your property boundaries. That means if you hear/see Greater
White-fronted Geese flying overhead from your yard you can count them.
That means if you can ID a Golden Eagle off in the distance from your
property you can count it. That means if you hear a Great Gray Owl
calling in your neighbor's yard from your back porch, you can count it!
Yard birding is fun and easy to do.
Central Oregon Yard
Lists for 2008 (updated often!)
This project is where you
can find what people are seeing in their yards at different locations.
The dates represent the first day that a species was seen.
To add your yard to this
list, please send me your name, general location and first day a
species was sighted this year.
Central Oregon Yard
10-Day Period Survey Data 2008
(will be posted when I have an idea of who will be involved this year)
The survey data 2008 page
has each participant's data on a separate page; click the named tabs on the
bottom to view.
To download a copy of the
data sheet (in MS Excel format), click here. Select save
from the dialog box and select a location where you want to place the
file. I also have an Excel sheet that I use
to gather sightings on a daily basis. This spreadsheet will
automatically keep track of the maximum number of individuals seen for each
observation period. Please feel free to modify the list of birds for
each month to fit your location.
(Please send me a copy of
your data--email the spreadsheet as an attachment-- after each 10-day period
or after every month ).
For these yard surveys,
observers are counting how many individuals of a species are seen during one
day over a 10-day period, then recording the highest count for that
period. Why? While yard lists over a year or even life time tell
you what you can see from one place, it does not tell you anything about
migration patterns, residents, etc. By collecting information about who
is around and when we can learn about yearly cycles that even resident
species may have, when migration movements happen, which species are
involved, and even when breeding birds are successful.
For example, if five individuals of species X
are seen on the 1st day, seven on the 3rd day, six on the 4th, and three on
the 9th day of the period (other days there were no birds or no counting),
for this time period, seven is the highest count and would be recorded
for this time period for this species.

Central Oregon Yard Lists
for 2006
I have updated the lists to
conform with AOU taxonomic guidelines and have hidden the species that are,
as of present, not observed by anyone participating in the yard list
observations. As new species are seen, I will add those birds to the
list.
Birds seen on COCC class field trips for 2006
Here is a checklist of the
species found by at least some of the members of the COCC Bi103 class on
field trips to Hatfield Lake, Shevlin Park, Camp Polk Meadows, and Tumalo
State Park. Each site is visited four times on consecutive Tuesdays and
Thursdays.
