- Glaucidium brasilianum
Includes Ridgway's Pygmy-Owl; Tucuman Pygmy-Owl
Identification
Red, brown, and grey morphs occur, and tail varies having whitish, orange-buffy, or no bars. As with most Pygmy-Owls, there are pale areas on the back of the head imitating an extra pair of eyes.
Distribution
From Arizona and south-east Texas through Mexico and Central America to South America where found east of the Andes to Argentina.
Taxonomy
In the past, Austral Pygmy-Owl has been considered part of Ferruginous Pygmy-Owl. Konig et al.2 additionally have split subspecies ridgwayi (including cactorum and the not universally recognized saturatum) as the full species Ridgway's Pygmy-Owl Glaucidium ridgwayi which would include the birds from Panama to the USA; this has not been recognized by any of the world-wide checklists. Tucuman Pygmy-Owl (ssp tucumanum) is also sometimes split as full species.
Subspecies
Thirteen subspecies are recognized by Clements1.
- G. b. cactorum: South-eastern Arizona and western Mexico (Sonora to Oaxaca)
- G. b. saturatum: Southern Mexico (Chiapas) and Guatemala
- G. b. ridgwayi: Southern Texas (lower Rio Grande Valley) to Panama (Canal Zone)
- G. b. medianum: Tropical lowlands of northern Colombia
- G. b. margaritae: Isla Margarita (Venezuela)
- G. b. phaloenoides: Tropical northern Venezuela, Trinidad and the Guianas
- G. b. duidae: Tepuis of southern Venezuela (Mount Duida)
- G. b. olivaceum: Tepuis of southern Venezuela (Mount Auyan-Tepuí)
- G. b. ucayalae: Eastern base of Andes of south-eastern Colombia to Peru and northern Bolivia
- G. b. brasilianum: Southern Amazonian Brazil to eastern Paraguay, Uruguay and north-eastern Argentina
- G. b. pallens: Chaco of eastern Bolivia, western Paraguay and northern Argentina
- G. b. stranecki: Southern Uruguay to central Argentina
- G. b. tucumanum (Tucuman): Subtropical western Argentina (Salta and Tucumán to Córdoba)
Habitat
