I found this bird on October 20 here in East Jordan NS. This is the first time I've seen this species in several years. It is very similar to its Eastern cousin in habits but couldn't be more different in appearance with it's bright yellow belly and pale grey head and back. I checked again the following day but couldn't find it. I was hoping for better images but had to be satisfied with these.
When I first found the bird it was on the perch in the bottom photo which was a great spot for a photo but I couldn't get close enough. I was lucky to have the bird land close by for the top image but, typical for a Kingbird it landed on the top of the tree so I could only get a belly shot.
