A member of the notoriously difficult to differentiate empidonax genus, the alder flycatcher is most easily differentiated by it's call which sounds like it's calling "free beer!". As the name suggests, they breed in wet thickets of alder as well as maple and birch. It's closest relative is the Willow Flycatcher although outside of migration their overlap zone is comparatively small.
