Molecular tools reveal diets of insectivorous birds from predator fecal matter [PDF]
, 2013 The emerging field of molecular scatology enables critical testing of food web theory. The non-invasive application of molecular tools allows for sequencing of prey DNA from predator fecal matter, evaluating diet breadth and foraging guild.

Sherman traps, bucket cameras, eDNA—oh, my: A comparative study of small mammal monitoring methods
Wildlife Society Bulletin, EarlyView.Comparison of Sherman live trapping, bucket camera traps, and airborne environmental DNA (eDNA) for assessing small mammal communities in restored prairies. Bucket cameras detected the highest species richness, live trapping provided the most precise species identifications, and airborne eDNA detected unique taxa.

Diet, phenology and body size shape nutrient release by songbirds
Functional 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,

Should we further investigate the cascading effects of introduced fish on insectivorous birds?
, 2019 We investigated whether the introduction of fish (brown trout, Salmo trutta) in previously fishless boreal lakes could alter the aquatic insect subsidy and affect the nesting population of insectivorous migratory birds, with a particular focus on the ...

Journal 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.
