to the ornithology and herpetology of Guatemala
Knut Eisermann and Claudia Avendaño of CAYAYA BIRDING contributed an update on the distribution of owls in Guatemala:

Knut and Claudia contributed to a study on the nesting ecology and habitat use of Flammulated Owl in Guatemala, which represents the first nesting record southeast of the Isthmus of Tehuantepec:

Knut and Claudia contributed to a study on the nesting ecology of Savannah Sparrow in Guatemala. This is the first documentation of the subspecies Passerculus sandwichensis wetmorei since the type specimens were collected more than 100 years ago:
Eisermann, K., C. Avendaño & E. Matías. 2017. Nesting evidence, density and vocalisations in a resident population of Savannah Sparrow Passerculus sandwichensis wetmorei in Guatemala. Bulletin of the British Ornithologists' Club 137: 37-45.
Knut contributed a short note on noteworthy records of two amphibian species, including the bizarre Burrowing Toad:
Eisermann, K. (2017) A new locality and elevational range extension for Rhinophrynus dorsalis Duméril & Bibron, 1841 (Anura: Rhinophrynidae), and a noteworthy record for Hypopachus variolosus (Cope, 1866) (Anura: Microhylidae) in Guatemala. Mesoamerican Herpetology 4: 688-692.
