Songbirdz
Description
Each item in the collection represents a species of bird with an associated audio recording and unique image. Minting is now live at: https://songbirdz.cc

Built using images from DALL·E 3 and audio from The Cornell Guide to Bird Sounds: United States and Canada (v2021).

To start, the image and species name is hidden for each bird until it has been successfully identified via an onchain transaction. The contract uses merkle trees to store an onchain hash of the species, image, and audio for each item in the collection.

The smart contract governing the NFTs, the back-end code for the web server, and the front-end code for the web application are all open-source (MIT License). Every NFT in the collection is released under the Creative Commons Zero (CC0) license, granting users freedom to use, remix, and share the artworks without any restrictions.

As a new onchain developer and an avid appreciator of birds, I hope you find this collection interesting, useful, and enjoyable. Thank you!
