羽毛识别工具通过特定的标准缩小搜索范围，帮助您对发现的羽毛进行分类。用户可以通过选择一种或多种视觉图案、识别最显著的颜色，以及对羽毛的总长度进行分类（从小于 8 厘米的“小”到大于 24 厘米的“巨大”）来优化搜索。 此外，该工具允许您根据羽毛的身体部位进行筛选，如果您对鸟类品种有所了解，也可以按特定的鸟类群体（如猫头鹰）进行筛选。用户可以结合多种筛选条件来提高准确性，或者不选择任何类别以在整个数据库中进行搜索。这种直观的多步流程使您更容易将样本与正确的鸟类进行匹配。

IDENTIFY FEATHER TOOL

     

Use the buttons above to select different criteria for a feather you've found and attempt to identify it.

Select the pattern or patterns that most closely match your feather. Many feathers will match only a single pattern, but others, such as a barred feather with a broad white tip, will be best described by selecting more than one pattern.
Determine the most characteristic or striking color on your feather, and check the appropriate selection from the list. By characteristic color, we mean the color that is most noticeable on the feather.
To further narrow down your search, you can specify the size of your feather in one of four categories:

SMALL: total length less than or equal to 8 cm (approximately 3 inches); MEDIUM: total length 8-16 cm (3 - 6 inches); LARGE: total length 16-24 cm (6 - 10 inches); or HUGE: more than 24 cm (10 inches). If you don't specify a size category, feathers of all sizes will be searched.

If you know the position of the feather you are trying to identify, you can significantly narrow your search by choosing from the options below. If you're not sure what type of feather you have, select "Search All Feathers". No selection will still search all feathers.
For more information, see:
Identifying Feather Position.
Sometimes, you'll have a good idea what kind of bird your feather came from. For example, a barred feather with a soft, fuzzy texture is probably from an owl. Selecting options from the list below will allow you to restrict your search to particular groups. You can select as many as you wish.
