@ljmanning Thank you, Laura! I appreciate the link you provided and, yes, it confirms that this is, indeed, an Eastern Kingbird. I had never heard of them and my search yesterday on the same web site didn't lead me to this particular bird. Again, I really appreciate your help and comments!
@milaniet@amyk@seattlite@happysnaps Thanks, everyone! So happy to now know what the bird is and to realize that my list of birds I see in our area is growing!
