Differences of morphological and ecological characters among lineages of Chilean Rhinocryptidae in relation an sister lineage of Furnariidae. [PDF]

open access: yes, 2008
Eight species of Rhinocryptidae are recognized from Chile. Moreover, morphological, ecological and behavioral differences among two lineages of _Scytalopus_ and two species of _Pteroptochos_ are unclear. According to our results, there are no decisive

Insect ectoparasites from wild passerine birds in the Azores Islands

open access: yesParasite, 2020
A total of 266 wild passerine birds (Passeriformes) representing eight species and nine subspecies from three islands of the Archipelago of the Azores were examined for ectoparasites. Two species of louse-flies Ornithomya avicularia and Ornithoica turdi (

Ecological constraints on elevational gradients of bird species richness in Tajikistan

open access: yesAvian Research, 2022
The avifauna in Tajikistan has been widely studied for the last century, but specific work on species richness pattern along elevation gradients in Tajikistan is rarely investigated. Here, we reported the first study of bird species richness (BSR) in the

How Passive Acoustic and Traditional Monitoring Estimate Bird Diversity Across Habitats

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We compared traditional bird counts (PC) with passive acoustic monitoring (PAM) in a heterogeneous Alpine landscape. PAM recorded twice as many species, with a strong correlation between species richness and the bird counts (rs = 0.71); however, there were significant differences depending on habitat type.

Diet, phenology and body size shape nutrient release by songbirds

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals can dramatically alter ecosystem structure and function through the cycling and transport of nutrients in their waste. While birds are particularly capable of influencing nutrient cycles due to their high mobility, abundance, metabolism and functional diversity,

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

open access: yesJournal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.
