I believe it stems from twitter being a blue bird and Nostr OGs settling on a purple ostrich aka nostrich being the official mascot for Nostr.
Someone else may be able to chime in with more detail.

For the Nostr piece:
Nostr is a system that allows people to share notes and other things with each other in a way that's secure and private. There are two main parts to the system: clients and relays.
Each person who uses Nostr has a client program on their computer or phone that they use to send and receive notes. These clients are identified by a special code called a public key, which is like a digital ID.
There are also relays, which are servers that help people send and receive notes. Anyone can run a relay, and there can be lots of them.
When you send a note in Nostr, your client program adds a digital signature to it, kind of like signing your name. When someone else receives your note, their client program checks the signature to make sure it really came from you and hasn't been tampered with.
To follow someone on Nostr, you just tell your client program to look for notes from their public key. Your client program will then check with the relays you've chosen to see if there are any new notes from that person.
The relays don't talk to each other, so they can't see what notes are being sent between clients. This helps keep things private and secure.

Thank you for answering that part! Well said!
