Additional Resources

The value of Piranga will continue to increase as more and more people contribute images and information. The site has been designed to accept information on all North American (and soon South American) species, and we encourage everyone to add to this site.

Nevertheless, banders may also want to examine other sites that provide information on ageing and sexing birds. Differing lay-outs and content may assist with learning, much like the benefit derived from looking at several different field guides when trying to identify a bird.

The following is a partial list of online photographic resources that may help bird-banders learn to age and sex birds in the hand. If you are aware of additional resources that may be helpful, please contact us and we will consider adding them to the list.
