Additional Resources

We have designed Piranga to house information on all Western Hemisphere birds, and expect its value to increase as more and more people contribute images and information.

Nevertheless, banders may also want to examine other resources that provide information on ageing and sexing birds. Differing layouts and perspectives may assist with learning, similar to the benefit derived from looking at multiple field guides when trying to identify a bird.

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