Confusing species Please be sure you can distinguish between similar species such as the Purple Finch and House Finch, the Chipping Sparrow and American Tree Sparrow, and the Sharp-shinned Hawk and Cooper's Hawk. A current field guide can help, and we have provided a quick reference guide to help tell them apart. Note that House Finches are more common than Purple Finches. Also, please be sure to send descriptive details of any Chipping Sparrow or Cooper's Hawk sightings. If you observe an unusual species, please include a detailed description of the bird's appearance and behavior.
Photographs are always helpful.
Without documentation, unusual reports cannot be confirmed and may not be included in the final tally. The survey reports are computerized over the spring and summer with final interpretation in the fall. All participants receive a copy of the results with next year's forms when they are mailed in January. The results will also be posted on the web site as soon as they are compiled. How to submit your results Please fill out the form completely, and mail it to ASNH at the address on the form.
