Alder Flycatcher (Empidonax alnorum)
Alder Flycatchers live in wet shrubby areas. They eat mainly insects and sometimes berries and seeds. They were previously categorized with Willow Flycatchers, as the only difference between the two species is their call. Alder Flycatchers can weigh 0.4-0.5 oz. and have a wingspan of 8.3-9.4 in. Their call is similar to that of an Eastern Phoebe, but says “fee-bee-o” instead. They are protected on the US Migratory Bird lists.

American Bittern (Botaurus lentiginosus)
American Bitterns reside in wet, marshy areas that are made up of freshwater and reed-like plants. Their diet consists mostly of aquatic animals such as small fish and invertebrates, but can extend to small rodents and insects. They have a wingspan of about 36.2 in. and can grow to be 13.1 - 17.6 oz. American Bitterns are usually heard, not seen, due to their exceptional camouflage and low calls. They have multiple calls that include “pump-er-luck,” “kok-kok-kok,” or “chu-peep.” They are protected on the US Migratory Bird lists.
