Colorado Field Notes



"Colorado Field Notes" is a monthly ebook publication
of the Colorado Birding Society.

Each Month's Issue includes articles relevant to that
month's birding around Colorado.

NOTE: "Colorado Field Notes" is now in PDF format.
This allows more computers and operating systems to read
the issues. In addition the PDF files are searchable and
can be copied. They can also put on mobile devices and
carried into the field.

Also included:
Recent photos of birds observed in Colorado.
That Month's Uncommon Bird Sightings.
Next Month's Colorado Statewide Bird Trips.

Because of the ebook format, Bird Sightings
can be updated even in past issues.

NOTE: issues are no longer in ebook format.
We still update issues with late additions of records.
