The Alder Flycatcher is a small migratory bird found in North America. Its name is derived from its preferred habitat, which is often near alder trees. The spelling of "Alder Flycatcher" is as it sounds phonetically when pronounced with the International Phonetic Alphabet (IPA) of /ˈɔːldər ˈflaɪkætʃər/. The correct spelling is important for accurate communication in both scientific and casual settings. With its distinctive "free-beer" call, the Alder Flycatcher is a unique and valuable addition to North America's avian diversity.
The alder flycatcher, scientifically known as Empidonax alnorum, is a small passerine bird belonging to the family Tyrannidae. It is primarily found in North America, where it breeds in various habitats such as wetlands, bogs, and alder thickets. Known for its distinct vocalizations, this species is often identified by its characteristic song, a distinctive "fee-bee-o" or "whit-a-wee-o" call.
Physically, the alder flycatcher is relatively small, ranging from 5 to 5.5 inches (13 to 14 cm) in length, with a dull olive-brown upper body and a whitish breast. It possesses narrow, pointed wings, a short tail, and a small bill. The name "alder flycatcher" is derived from its preference for breeding in alder-dominated habitats and its feeding habits as an insectivore. It primarily feeds on flying insects, particularly those in the mid-air, which it skillfully catches in flight.
The alder flycatcher's breeding season typically occurs from late May to early August. During this time, it constructs a cup-shaped nest made of twigs, plant fibers, and grass, often placed in the lower parts of shrubs or small trees. The female usually lays a clutch of three to four pale greenish eggs with brown markings, which are incubated by both parents for approximately two weeks. The hatchlings are altricial, meaning they are initially dependent on their parents for food and care.
Due to its relatively subtle appearance and close resemblance to other members of the Empidonax genus, the alder flycatcher can be challenging to distinguish from several nearly identical species and hybrids. Therefore, accurate identification often requires careful
The word "alder flycatcher" has a relatively straightforward etymology.
1. Alder: The term "alder" refers to a type of tree belonging to the genus Alnus. These trees are typically found near wetlands and bodies of water. The name "alder" is derived from the Old English word "alor", which ultimately traces back to the Proto-Germanic word "*alus".
2. Flycatcher: The term "flycatcher" refers to a family of small to medium-sized birds known for their habit of catching insects on the wing. The word "flycatcher" comes from combining the words "fly" (referring to the insects they catch) and "catcher" (referring to their hunting behavior).
So, when combined, "alder flycatcher" simply describes a type of flycatcher bird that is frequently found in alder tree habitats.
