species crown forehead eye-ring bill lower mandible throat and undersides wingbars wing panel contrast primary extension tail
Acadian Flycatcher peaked shallow crisp large orange white contrasting throat, undersides bold long medium, fat
Yellow-bellied Flycatcher round steep crisp small to medium orange low contrast yellow throat and undersides bold yes long short, narrow
Hammond’s Flycatcher rounded to peaked very steep bold messy small dark (mostly) low contrast grey throat, chest medium no long short, narrow
Willow Flycatcher peaked shallow indistinct or no medium to large orange medium contrast throat dull no medium short, fat
Alder Flycatcher rounded shallow to medium indistinct, but thin crisp medium to large medium contrast throat medium to bright strong medium short, fat
Pacific slope/Cordilleran Flycatcher crested medium distinct, tear-dropped medium orange low contrast throat. Overall yellow coloration above and below strong no medium medium, narrow
Dusky Flycatcher round to flat medium indistinct and messy small to medium low contrast pale grey throat and chest dull no short medium, narrow
grey Flycatcher flat shallow messy large orange low contrast pale grey throat and undersides dull no short long, narrow, droops slowly downward; white outer feathers
Least Flycatcher round steep bold but messy small white contrasting throat, chest, bellly bold yes short to medium short, narrow
