It is with great hesitation that I post a sighting of an Olive-sided Flycatcher 
on Prescott Road in Little Bennett Regional Park. I initially thought that it was 
a pewee, but it was larger without wing bars, and it looked like it was wearing 
a vest. I have not seen an Olive-sided Flycatcher in 8 years and that one was 
identified for me. However based on the fieldmarks it is the only logical 
conclusion. How rare is this bird at this time of year?
