I live in Northern Virginia and about three years ago I was driving around my neighborhood and saw the brightest bird I had ever seen. Highlighter green. Now the same bird (or that's my guess) comes to my feeder regularly. It holds its own fending off the other birds and seems quite happy. Last winter it snowed for weeks straight...Any guesses about whether or not it is the same bird. Did it migrate and come back. I read on-line about wild monk parakeets in my area but the pictures don't match. Yellow head bright green body with balck wavy lines on the wings. I know nothing about birds can you help me solve the mystery?
