This ID seems very difficult Referencing large National Geographic complete hardcover field guide (North America) 3rd edition Alderfer Dunn P. 436 - passage for Out-of-Range Myiarchus Flycatchers Based off of that passage, species likely isolated to Great Crested or Ash-Throated Going to go with Great Crested because the bill seems thicker and is not all black Thanks for reviewing Additional details annotated on 10/12 from memory: Dog & I were on our 2nd & final loop of Nursery clockwise around 0915 time Bird was on outer lake side of loop adjacent to trail Noticed a medium-large size Flycatcher at NW "corner" of loop What was immediately noticed was the bull head I thought it was perhaps an Olive-Sided but that didn't seem quite right Attempted to get some photos albeit they ended up being from awkward angles Of course noticed the breast rules out Olive-Sided The bird did not seem to choose conspicuous perch locations Was staying somewhat hidden in mid story Unfornately, did not hear the bird vocalize I think it did successfully capture a prey item while observed I am just recently learning trees & shrubs among other naturalist things Therefore, I am not not certain the tree here If I recall, there were 2 different trees side-by-side the bird was working at foraging Hope this helps 10/14: Referencing new guide that I purchased Field Guide to North American Flycatchers Tyrannus and Myiarchus version (there is a separate guide for Pewees & Empids) Cin-Ty Lee plus Illustrator Andrew Birch Princeton 2024 Changing to Ash-throated although I will definitely defer to expert analysts Referencing the many comparison plates Subtle differences in primary projection, tertials, chest contrast, head & face color pattern Especially the undertail pattern (dark brown hooks around tip) Many helpful illustrations with descriptions
