Little chippy eat from my hand

This little chippy came for food almost every day in this spring til May 2023, this is the last time and we never saw her since.
Day after day, she never came back...
Perhaps she found better food source somewhere else?
Perhaps she was killed by traffic?
Perhaps she was captured by predator?
Perhaps she simply age and die?...

Nobody knows where you are
How near and how far...
Oh how I miss you little chippy...
