- Elaenia albiceps
[edit] Identification
Length 15cm. Typical appearance of other small olive flycatchers, but has a large white crown patch, which is usually raised and quite obvious. Two wing-bars, strong and white in the Chilean subspecies, but less distinct in the Peruvian subspecies, which also has a yellowish crest and eye-ring.
[edit] Distribution
Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Falkland Islands, Paraguay, Peru, South Georgia and the South Sandwich Islands, and Uruguay. Accidental vagrant to the United States with one record in Texas[3].
[edit] Taxonomy
Six subspecies are recognized. Among these, two are especially noteworthy because they may eventually be separated into different species:
- E. a. modesta (Peruvian) is found in Peru and in lowlands in the northernmost part of Chile; at least partly resident year round
- E. a. chilensis (Chilean) is breeding significantly south of modesta but highly migratory and completely leaves the breeding areas in winter.
The other four subspecies are:
- E. a. griseigularis
- E. a. diversa
- E. a. urubambae
- E. a. albiceps
together ranging from Colombia to Bolivia.
[edit] Habitat
Shrubland, forests or gardens, with slight differences in preference for the different populations; the Peruvian subspecies can be found in urban areas, agricultural areas, and riparian areas while chilensis seems more closely related to forest in breeding season.
[edit] Behaviour
Some populations are residents while others migrate north in winter.
