Feather Sample Collection Instructions



To ensure accurate DNA testing, please follow the instructions below when submitting feather samples.




Number of Feathers Required



Submit 5 to 7 plucked feathers per bird.


Submitting multiple feathers improves DNA yield and allows for repeat testing if needed.




Labeling Samples



Please label each envelope before or immediately after collecting feathers.


Each envelope should include:

Bird name, band number, or clear identifier
Owner name or order number if submitting multiple birds



Collect feathers from one bird at a time and place them directly into the labeled envelope.




Acceptable Feathers


Feathers must be plucked, not cut
Small to medium body feathers are preferred
Feathers should have an intact base
Dry feathers are normal and acceptable





How to Collect Feathers


Gently pluck 5 to 7 small body feathers from the breast or saddle area
Place feathers directly into the labeled paper envelope
Do not cut feathers with scissors
Avoid large flight or tail feathers
Do not intentionally pull blood feathers



Blood is not required and is not recommended for mailed samples.




Collecting Samples From Multiple Birds



If you are collecting feathers from more than one bird:

Collect and package feathers from one bird at a time
Wash hands or change gloves between birds
Avoid placing feathers on shared surfaces
Use a separate labeled envelope for each bird



These steps help prevent sample mix ups and reduce the chance of cross contamination.




Packaging Instructions


Place feathers in a paper envelope
Clearly label each envelope
Do not use plastic bags for feather samples





What Not to Send


Molted feathers found on the ground
Cut or trimmed feathers
Feathers without intact bases
Large wing or tail feathers
Feathers stored wet or damp





Important Notes



Feather based DNA testing relies on cells located at the base of plucked feathers. Fully grown feathers are typically dry and hollow, which is normal and expected. Submitting fewer than the required number of feathers may result in insufficient DNA and an inconclusive result.


Optional Line for Extra Protection



You may want to include this sentence at the bottom of the page:


Samples that do not meet submission requirements may result in delayed testing or inconclusive results.
