I have a bird that is absolutely driving me bonkers and has for the last few springs. I can't get a view on it, it is quite elusive. It sits high in the trees and makes a call: tweet, chee ree. It seems to travel with the house finches that arrive here in about mid-March. I have tried some of the on-line bird id sources and have failed to figure it out. I have also looked at and listened to most of the birds that are supposed to be arriving at that time, to no avail. Have you any clues for me? I have FINALLY gotten a recording on my camera video. Is it possible to D-mail (or E-mail) that to someone who might be able to help me out?
By the way, I live in the forested foothills of the Cascade Mountain range and have lots of conifers and also alder and maple.
