ALDER FLYCATCHER, COLONEL SAMUEL SMITH PARK,ETOBICOKE,TORONTO,ONTARIO, 6/7/2021

   Merlin Photo ID app identified this flycatcher as either an Alder Flycatcher or a Willow Flycatcher.  The easiest way to differentiate them is by their calls or songs.  Unfortunately this flycatcher was neither calling or singing.  I do believe this is probably an Alder Flycather because of the following:

• Whitish throat. A strong contrast between face and throat.  The Willow Flycatcher has a more grayish throat.
• Brownish olive upperparts.  The Willow Flycatcher has more grayish upperparts.
• White eyering. The Willow Flycatcher has a less prominent eyering
