Owls of Guatemala

Bearded Screech-Owl
Juvenile Bearded Screech-Owls Megascops barbarus.

Owls (Strigiformes) belong to the least studied birds in Guatemala. PROEVAL RAXMU Bird Monitoring Program contributed several studies enhancing the knowledge of these birds in Guatemala and Mesoamerica.

Owl diversity in Guatemala

PROEVAL RAXMU Bird Monitoring Program has updated the information on diversity, distribution, and conservation of owls in Guatemala, and contributed to the knowledge on the natural history of selected species.

Owls of Guatemala
Some owls of Guatemala: Fulvous Owl, Black-and-white Owl, Guatemalan Pygmy-Owl, Unspotted Saw-whet Owl, Stygian Owl, Bearded Screech-Owl, and Mexican Wood Owl.

Natural history of owls

PROEVAL RAXMU Bird Monitoring Program studies the natural history of selected owl species in Guatemala. The following contributions have been published:

Vocalizations of Guatemalan Pygmy-Owl (Glaucidium cobanense)
Results of our analysis of the vocalizations of the Northern Pygmy-Owl complex in Mexico and northern Central America support a specific split of Guatemalan Pygmy-Owl (Glaucidium cobanense) from the highlands of northern Central America and southern Mexico from Mountain Pygmy-Owl (Glaucidium gnoma) from the highlands of northern Mexico.

Vocalizations of Unspotted Saw-whet Owl (Aegolius ridgwayi) In 2013, PROEVAL RAXMU Bird Monitoring Program described several vocalizations of Unspotted Saw-whet Owl, including vocal field marks for telling it apart from Guatemalan Pygmy-Owl.

Nesting and habitat of Flammulated Owl (Psiloscops flammeolus) in Guatemala
We describe the first nesting record of Flammulated Owl in Guatemala, which represents the first nesting record south-east of the Isthmus of Tehuantepec.

Compilation of research needs and taxonomy of Neotropical owls

PROEVAL RAXMU Bird Monitoring Program contributed to an overview on research and conservation needs of owls in Mexico and Central America, presented during a symposium on Neotropical owls held during the IX Neotropical Ornithological Congress in Peru, November 2011.
