Here are some eBird maps showing all records for the month of April for several species of small flycatchers in eastern North America. A glance at these maps will show which species are possible in your area in the next few weeks, and this greatly simplifies flycatcher identification. For most of the east, through most of April, small flycatcher identification can be summed up in one short phrase – “It’s a phoebe” (see Eastern Phoebe map at the end of this post below).
Anything is possible, of course, and spring migration is getting earlier each year, but if you think you have found, for example, an Alder Flycatcher in Pennsylvania in April, you’ll need some photo or audio documentation to verify it.
Due to COVID-19, events planned for this spring are being rescheduled later this year, and you might experience small delays in orders from the web store. Thanks for your patience. Stay healthy and keep birding!
